Electric Dreams? The Jaguar E-Type Zero

The announcement in recent months that both France and the U.K. are to ban the sale of diesel and petrol vehicles by 2040 has sent shockwaves through the car industry and will force automotive manufacturers to step up the pace of change to hybrid and electric powered vehicles.

The French announcement in July by Environment Minister Nicolas Hulot is in line with the Paris climate accord and part of a commitment by the French Government for the country to become carbon neutral by 2050.

However, it was the loss of a Supreme Court battle to environmental group ClientEarth in 2015 that has forced the British Government to act. The U.K.’s air pollution problems have been in breach of the EU limits for years and several British cities have failed to meet standards on nitrogen dioxide levels since 2010. According to the Royal College of Physicians, around 40,000 deaths in the U.K. per year are caused by air pollution.

Perhaps a big cat that will not be on the endangered list?

All of the above is no doubt something of a nightmare to owners of vintage and classic cars that could in future years be penalised in some way or be simply seen as anti-social for using a “dirty” petrol driven vehicle. It, therefore, must come as some sort of relief that at least one company is offering an integrated option to solve this dilemma.

Jaguar Land Rover Classic Works in Coventry are part of the Jaguar Land Rover group responsible for maintaining, restoring and building continuation classic Jaguars. But it is their latest offering, the Jaguar E-Type Zero that allows owners “to have their cake and eat it too”.

The Concept Zero featured, is built around the 1968 Series 1.5 E-Type Roadster, which has been converted to utilise an electric powertrain that offers equivalent performance but with zero emissions. The conversion is fully reversible and future-proofs classic car motoring.

The good news is the conversion can be applied to any classic Jaguar built between 1948 and 1992 and is intended to preserve the looks and handling of the original petrol XK engined classics.

Lithium-ion batteries replace the XK petrol engine.

The lithium-ion batteries have the same dimensions and similar weight to the six-cylinder engine used in the original E-type and are placed in the same location. The electric motor (and reduction gear) lies behind the battery pack, in the identical place as the E-type’s gearbox. A propshaft then sends the power to a carry-over differential and final drive.

The electric power unit develops 220kw and compares favourably against the 198kw of the original XK6 petrol engine, and is 46kg lighter while the overall weight is 82kg lower than the Series 1 E-type.  It’s also quicker than an original E-type; 0-100km/h (62mph) takes only 5.5sec, about one second quicker than a Series 1 E-type. The 40kwh battery has a real-world range of 270km and can be completely recharged in six to seven hours.

An inverter hides in he boot.

Another positive aspect of the conversion is that by using an electric powertrain with comparable weight and dimensions to the outgoing petrol engine and transmission, the car’s structure, including suspension and brakes, doesn’t need to be changed. The E-Type Zero drives, handles, rides and brakes like an original E-type, thanks to a front and rear weight distribution that remains unchanged.

Outwardly there are only a few hints that this is no regular E-Type. The dash sports modified instruments and facia, inspired of course by the original E-Type and the headlights are L.E.D. in the name of energy efficiency.

I only hope owners of a Zero are given a USB to play through the cars sound system that features the sonorous melody of an XK engine, being driven hard….

Vale Angel Nieto 1947 – 2017

 

Nieto on the 125cc Garelli.

2017 has been a sad year for the sport of Grand Prix motorcycle racing. The passing of the incomparable John Surtees in March and the tragic road accident that unexpectedly claimed the life of Nickey Hayden in May have left a void in the eras these two great former World Champions represented.

Now the recent death of Angel Nieto, again to a tragic road accident, has created another great loss. His achievements paved the way in a sport that is now dominated by his countrymen.

Nieto passed away as a result of brain damage caused by a car that hit his quad bike on July 26th. The 70-year-old hit his head on the ground while travelling at low speed while traversing a roundabout on the Island of Ibiza. He was placed in an induced coma but his condition worsened and he died on the evening of Thursday the 3rd of August.

Nieto was the first Spaniard to compete in the motorcycle Grand Prix. Over a career that spanned 22 years from 1964 to 1986 he achieved 90 wins and 139 podiums from 186 starts. He won six 50cc World Championships and seven 125cc World Championship for a total of 13 titles, second only to Giacomo Agostini with 15 championships in the 350cc and 500cc class. Nieto won his six 50cc World Championships with Derbi, Kreidler and Bultaco. His seven 125cc world titles came with Derbi, Kreidler, Minarelli and Garelli.

Nieto was also awarded the Knight Grand Cross in the Order of Civil Merit in 1982 and the Knight Grand Cross in the Order of Sports Merit in 1993.

Mike Hailwood’s Isle of Man TT return

A triumphant return. Mike heading for victory in the 1978 F1 TT.

It was acclaimed as one of the greatest comebacks in motor racing history. After more than a decade away from the most deadly of all motorcycle road racing circuits, the Isle of Man TT, former 9 times motorcycle World Champion, Mike Hailwood, returned to the Island riding an NCR Ducati, to win the 1978 Formula 1 TT. As if to underline he had lost none of his skill and versatility, Hailwood competed again the following year to win the Senior TT on a works Suzuki RG500 two-stroke Grand Prix racer. After his fairy-tale comeback, the 39-year-old then hung up his helmet for good.

2018 will be the fortieth anniversary of Hailwood’s remarkable return to the Island, but it was in 1977, forty years ago in Australia, that a chain of events put in motion Mike’s reunion with motorcycle racing and the TT.

After limited success in car racing, a crash at the 1974 German Grand Prix ended Hailwood’s Formula One car racing career. The crash caused compound fractures of Mike’s left knee, but the right leg sustained a shattered heel and the ankle was pushed down and compacted. It became clear that the doctors couldn’t repair his right foot even after extensive surgery and rehabilitation. Mike and his family decided to move to New Zealand where he went into a partnership with Mclaren Marine.

Hailwood quickly became restless in his adopted country and when in 1977 he was invited to be the guest of honour at a historic race meeting “over the ditch” in Australia, it was just the medicine Mike needed.

The All-Historic meeting was held at Amaroo Park in New South Wales, a circuit well known around the globe for its annual 6 Hour production motorcycle race. It was at this meeting Hailwood met and raced against Australian Jim Scaysbrook. Jim had competed successfully in dirt track, reliability trials, desert racing and speedway, and was the first Australian to race in the AMA Motocross series in 1973.

The main event for motorcycles was the Keith Campbell Memorial unlimited race. Scaysbrook won the race on Alan Puckett’s 7R AJS fitted with a Seeley 630cc G50 engine with Hailwood in second place on the ex Kel Carruthers 500cc Manx Norton owned by motorcycle dealer Barry Ryan. Over the course of the Australia Day weekend, the two men became good friends.

Mike was also mates with Sydney radio broadcaster, Owen Delaney, whom he had met in New Zealand. Delaney offered to sponsor Hailwood to come back for the historic race at the Easter Bathurst meeting. Mike would ride Barry Ryan’s ex-Kel Carruthers Manx Norton again and Jim the Alan Puckett 7R AJS. The event had previously been referred as a historic machine demonstration but was officially upgraded to full race status for the 70 odd entrants. Scaysbrook took the win again at Mount Panorama, with Hailwood in second.

Jim Scaysbrook left and Mike Hailwood prepare for the 1977 Castrol 6 Hour production race.

Hailwood returned to Australia once more for a historic meeting at Winton to pilot Charles Edmonds Manx Norton and was enjoying racing again so much that Delaney started to put together a deal to have Hailwood and Scaysbrook team up for the October Castrol 6 Hour production endurance race.

It was again a turn of events and a casual conversation that contrived to bring Hailwood back to the Isle of Man. In August 1977 a couple of months before his Castrol 6 Hour debut Mike attended the British Grand Prix at Silverstone. It was the first year the British Grand Prix was held on the mainland due to the top GP rider’s boycott of the Isle of Man TT because of the deadly nature of the street course. In the paddock at Silverstone for an F1 TT support race was Steve Wynne, owner of Sports Motorcycles in Manchester. Wynne had entered his rider, Roger Nicholls, several months earlier at the Isle of Man TT on an NCR (the unofficial factory race shop) Ducati 860cc endurance racer.

Wynne was still seething over Roger Nicholls loss to Phil Read in the first-ever F1 TT, which was in effect a single race World Championship. Read, a seven-time World Champion was making a comeback to the Isle of Man and Honda Britain, wanting to cash in on the publicity, provided a special “works” endurance 820cc racer. The F1 TT race was to be held over six laps but was run in wet wintery conditions. Although Read led for most of the race Nicholls needed only one fuel stop on the Ducati to the Honda’s two. At the halfway stage the race officials decided to shorten the race, which Honda got wind of, but the officials did not inform the other competitors handing Read and Honda the win from Nicholls by under forty seconds.

Hailwood was introduced to Wynne in the paddock and according to Steve, it was a coming together of two upset parties. Wynne because he felt cheated out of the F1 TT title and Hailwood, who had been snubbed by Honda when he’d approached them for a ride in the 1978 season. A short conversation and a handshake were all it took for the wheels to be set in motion for Hailwood’s come back to the Island on a Wynne prepared NCR Ducati. Although Mike had initially offered to ride for free under an assumed name, his longtime friend and manager, journalist Ted Mcauley, convinced Hailwood to “go public” on his comeback. A formal single page agreement was typed by Wynne to make it official and Hailwood was to be paid the princely sum of one thousand pounds.

Back in Australia preparations were also being made for Hailwood and Scaysbrook’s appointment with the Castrol 6 Hour production race. Owen Delaney had a friend called Malcolm Bailey who owned a motorcycle wreckers called Moreparts. Not surprisingly they arranged the purchase of a Ducati, and Scaysbrook, through his contacts in advertising, found sponsorship in the shape of Snack Potato Chips.

Unfortunately, the 1976 model Ducati 900SS purchased used a right foot gear shift, which was not ideal because of Hailwood’s injured right ankle from his Formula One car crash. The 900SS was sold and replaced with a 1977 square case 750SS, which had a left foot shift. The main weakness with the Ducati was its ground clearance around the mainly right-hand corners of Amaroo Park that caused the front header pipe to continually drag on the ground.

The Moreparts team qualified well but were handicapped by the Le Mans style start because the Ducati had to be kick-started, while the competition just pushed a button. Jim and Mike though managed to pick their way through the field finishing sixth outright and second in the 750cc class. A pretty good achievement considering Hailwood insisted he would only compete in the race “just for fun”.

The Moreparts team sponsors, Snack foods, had South Australia targeted next as part of a national campaign to launch their new potato chips brand, so in March 1978 the team were entered in the Adelaide 3 Hour production race at Adelaide International Raceway. This would be only Mike’s second race on the V-twin Ducati. A practice crash by Scaysbrook saw an all-nighter to rebuild the Ducati for the race using parts offered by the Ducati Owners Club from their own bikes.

During the race, Jim and Mike almost ran out of fuel during their stints, both times somehow managing to get back to the pits. Unfortunately during the rebuild oil had only been replaced in one of the damaged fork legs, which bottomed out under heavy braking locking up the front wheel. A top ten finish in the race was quite an achievement for the duo.

The Easter Bathurst meeting was next on the calendar with Jim riding the Ducati in the 750cc production class while Mike was entered on the Milledge TZ750 Yamaha in the unlimited class. Jim had arranged the ride for Hailwood after Bob Rosenthal, the bike’s usual rider, elected to miss the Bathurst meeting. It would be good preparation for the TT as Mike had also secured, thanks to Mcauley, Martini sponsored Yamaha’s for his TT return.

Bathurst was of mixed fortunes for the pair, with Scaysbrook winning the 750cc production race on the Ducati and setting a new lap record for the class, while, in atrocious weather, Mike finished 9th in the unlimited race having had to pit twice with fouling spark plugs.

Now it was the TT that beckoned. Wynne had successfully secured three of the NCR 860cc Ducati endurance racers. One each for Hailwood, Nicholls and Scaysbrook and received them from the factory with plenty of time to prepare the racers for the F1 TT. Mike also had the Martini sponsored Yamaha’s at his disposal. Known as Team Hailwood Martini, Mike had a production TZ 250 for the Junior TT, an ex-Agostini OW20 for the 500cc Senior TT and a production TZ750 for the 1000cc Classic TT. Turning the spanners for the Martini Team were Mike’s former mechanic Nobby Clark and respected technician Trevor Tilbury.

The first event of the TT meeting was the F1 race. The crowds of spectators had swollen thanks to Hailwood’s comeback, although there was some trepidation in the minds of the fans. Could Hailwood still do it? What if he got hurt or even worse? The spectators knew Mike was putting the substance of legend on the line. And it wasn’t just Read riding a factory Honda, TT regular and a winner of two 1000cc Classic TT’s John Williams was on a second factory Honda, while Tom Herron, Tony Rutter and Helmut Dahne were on works supported dealer entries.

Read led the 63 competitors away for the six-lap 226.38 mile (364.32km) race. But all eyes were on the number 12 Ducati starting from the fifth row (Mcauley had requested the number 12 from the A.C.U. as it represented the number of Hailwood’s TT victories). The grandstand crowd rose and applauded as Mike set off in pursuit of Read.

From a standing start, he logged a new lap record of 109.87mph (176.8kph) taking 90 seconds of Read’s existing record. Hailwood, who was ahead on time, chipped away at Read’s lead until they were on the road together going over the Mountain. Hailwood was 100 metres ahead as they came down the Mountain and headed for a fuel stop. They pitted together with Read getting away first and Hailwood in close pursuit. Soon Mike was in Read’s wheel tracks pushing the Honda along. Blue smoke started to appear from the Honda’s exhaust on the down changes and with 64 miles (103km) to go the Honda expired and Read’s race was run. To the roar of the crowd, Hailwood took the checkered flag and another TT victory. On his way to the token TT F1 World Championship, Hailwood had also set a new lap record of 110.627mph (178.037kph) for the class.

Read later admitted he had over-revved the Honda to try and stay ahead of Hailwood, but unbeknown to Mike when he shut the Ducati’s throttle off crossing the line a bevel gear failed. A hundred metres earlier and it would have been John Williams on the other factory Honda that would have won the race. It was a fairytale come true for Hailwood, Wynne, and Ducati.

Hailwood hunts down Read in the 1978 F1 TT.

Unfortunately, the other three TT races Team Hailwood Martini had entered weren’t to be so successful. In the Senior TT, a steering damper on the OW20 TZ500cc Yamaha broke causing Hailwood to stop at Ramsay to try and effect repairs before returning to the pits and putting himself out of contention. In the Junior TT Mike finished in 12th place on the production TZ250 and in the 1000cc Classic TT, a faulty crankshaft failed on the TZ750 ending his race. Such is the fickleness of the TT.

Mike had agreed to do some TT F1 races in England, as part of the MR TOPPS/ACU TT F1 British Championship series and the British Grand Prix TT F1 support race. Post TT was Mallory Park a tight short circuit not suited to the Ducati. Showing skill and patience Mike eventually romped home to victory beating again many of his TT rivals and in Wynne’s opinion a greater triumph than the TT win. Donnington Park was next but Hailwood crashed out of the race while in the lead, although he set an equal lap record to the eventual winner Roger Marshall on a Honda. At the British Grand Prix TT F1 support race, the Ducati was out powered on Silverstone’s high-speed straights. John Cowie on a Kawasaki won the race, but Mike still managed a third place podium. However, Hailwood still had unfinished business in Australia

With new sponsorship from Australian clothing manufacturer Golden Breed, the now outclassed Ducati 750cc SS was entered in the October 1978 Castrol 6 Hour production race. Teamed once again with Jim Scaysbrook things didn’t start well when Mike crashed during Thursday practice. A rebuild was required and again it was local Ducati owners that helped out with spare parts. A new rule that year required a nominated reserve rider. Stu Avant was the rider and he was obliged to practice on the Ducati. Unfortunately, Stu crashed the bike again, which necessitated another rebuild. On Saturday during qualifying, Mike put in one lap and the engine blew a big end bearing.

Another rebuild, but by race day they still hadn’t qualified to compete in the race, but the officials wisely decided to turn a blind eye and allowed them to start. Mike did the first stint and was practically last away at the Le Man’s start because of his injured ankle and having to kick-start the Ducati. Hailwood had them into the lead of the 750cc class when he handed over to Scaysbrook. Ten laps later, after such a promising start, the Ducati slid out from underneath Jim in The Loop and their race was over.

This wasn’t the end of Mike’s production racing adventures in Australia though. He teamed with Scaysbrook again for the Adelaide 3 Hour in early 1979 on Jim’s own Honda CB900FZ. But fate was against them again and a loose number plate had the duo black-flagged but they managed to resume the race after repairs had been made and finished a creditable 10th place.

However, Mike was not done with the Isle of Man TT yet and entered again in 1979 on a Sports Motorcycle supplied factory NCR Ducati’s in both the TT F1 race and the 1000cc Classic TT. He was also entered in the 500cc Senior TT on a Suzuki GB RG500. But the alarm bells started ringing for the Sports Motorcycles team at a test session and press conference at Misano in Italy for the NCR Endurance Racing Team. Mike’s TT F1 machine was unprepared and sported a gear-shift the reverse of what Ducati knew Hailwood required. The problem was Ducati’s ongoing financial situation, which was controlled by an Italian Government holding body EFIM who would only supply a budget for the Endurance Team.

Mike went out and tested the cobbled together machine only to select a false neutral and instinctively hit second gear instead of fourth. The resulting high side crash gave Hailwood three broken ribs and a badly bruised arm only two months out from the TT. In the meantime, a financial compromise was found with Ducati to pay for the racers by invoicing the British importer Coburn and Hughes who would then invoice Sports Motorcycles for the machines.

During practice for the F1 TT, it became clearly apparent that the NCR Ducati handled woefully. It no longer used the Vaspa frame of the 1978 machine and the FIM had tightened the TT F1 regulations, which now required the use of production crankcases instead of the special sand cast ones of the previous year. Hailwood also told the team the engine was less powerful than the ’78 unit. Something needed to be done. The Sports Motorcycles team decided to send for Roger Nicholls 1978 TT F1 Ducati racer, which was on display in the Luton showroom of the Ducati importer Coburn and Hughes. The idea was to transplant the 1979 engine into the 1978 chassis.

The bike arrived midday Thursday of practice week and the engine was installed into the frame, but there were problems with fitting the exhaust system of the ‘78 bike plus numerous ancillary parts that needed new brackets made. Finding enough steel in the early hours of the morning was a problem but fortunately, a supply was found at the back of the workshop which was the generator room of the Palace Hotel where old furniture was stored, including some steel bed frames. After a mammoth effort, Hailwood had something that represented a competitive motorcycle to defend his and Ducati’s title on. It was aptly nicknamed the “Bedstead Special” by MCN journalist Peter Howdle who knew how much work had gone into preparing Mike’s bike.

It has gone down history that Hailwood finished fifth in Saturday’s F1 TT, although he had somehow managed to claw his way up to third on the recalcitrant Ducati at the halfway mark. On the final lap of six, plunging down Bray Hill, Mike lost fifth gear. The over-revving engine then cut out. Hailwood stopped at Hillberry to find vibration had broken the bracket holding the battery, which came adrift disconnecting the wires. Mike reattached the battery, shoved it back into the bike to limp home fifth.

But Hailwood’s big moment was to come in Monday’s Senior TT. Riding a Suzuki RG500 he became only the third man to lap the Island in under 20 minutes on his way to victory setting a new lap record of 19m 51.2s at an average speed of 114.02mph (183.497kmh). It was a victory that confirmed what everybody knew, Hailwood was still master of the Island.

In preference to the NCR Ducati that was supplied specifically for Friday’s 1000cc Classic TT, Hailwood decided to use the Suzuki RG500. It became a race that many would compare to the epic battle between Mike and “Ago” in the 1967 500cc TT. His main opponent was Glaswegian Alex George aboard the “works” 998cc Honda and it would become a two horse race with the other riders becoming extras as the drama played out.

Mike’s Suzuki had been rebuilt overnight after a minor fault was discovered, but it was George who led by 9.2 seconds after lap one of the six-lap race. Hailwood closed the gap to 4 seconds on the next. After posting identical lap times at the halfway stage it was Honda works team efficiency and the advantage of a quick filler that sorted out the pit stops. It was also the first time at midpoint a TT had taken under an hour. George led by 4.2 seconds but by lap 5 Hailwood had taken the lead by a mere four-fifths of a second and still held an advantage on the last lap at Ballacraine, but at Ramsey, he was behind again. George had come back from behind and maintained his lead to take the win by just 3.4 seconds. Hailwood had announced that it would be his last TT and although he did so without taking another win the fans were not disappointed.

Hailwood was pencilled in once more to take in the post TT races at Mallory Park, which was part of the Forward Trust/MCW TT Formula 1 Championship but decided to look for more competitive machinery than the NCR Ducati. A Paul Dunstall Suzuki was his choice but brake issues saw Mike withdraw from the running. Donnington Park was the next round and Mike’s last race. A crash in practice saw him heading for the hospital with a broken collarbone. After having pins inserted he checked himself out against Doctors orders on race day and returned to the track to be driven around the circuit to say goodbye to the thousands of fans who had come to see him.

By then Hailwood had moved back to England and had opened a motorcycle dealership in Birmingham with friend and former 250cc World Champion Rod Gould. Only two years later in 1981, the sad epitaph to this colossus of motorcycle racing was written. A tragic road accident claimed Mike and his 9-year-old daughter Michelle’s lives. His son, 7-year-old David, was also in the car but survived with minor injuries.

In 1968 Hailwood was awarded an M.B.E. in the Queens Honours List for his services to motorcycling and he also was awarded the Seagrave Trophy in 1979 in recognition of his two TT wins in 1978 and 1979. Mike became a Federation Internationale de Motocyclisme “official legend” in 2000 and was inducted into the American Motorcycle Association Hall of Fame that same year. 2001 saw Mike’s induction into the International Motorsports Hall of Fame. Hailwood had also been awarded the George Medal for bravery after pulling Clay Regazonni from his burning F1 car at the 1973 South African Formula One Grand Prix.

During a Grand Prix career that spanned 10 years from 1958 to 1967, Hailwood won 76 Grand Prix and claimed 112 podiums from 152 starts.  He was World Champion 9 times scoring three  250cc World Championships, two 350cc World Championships and four 500cc World Championships. He was also the first rider to win four consecutive 500cc World Championships. Mike won a total of 14 Isle of Man TT’s before retiring permanently from the sport.

“Mike the bike” M.B.E. G.M.; to many the greatest motorcycle racer of all time.

Freddie Spencer: FEEL My Story

I have been an enthusiast of Grand Prix motorcycle racing since the early 1970’s and always relished reading the latest news, race reports and interviews in the specialist press. To a degree, it allows a certain amount of insight into the character of our racing heroes but like anyone who is thrust into the media spotlight, the public image does not fully reveal the person.

For example, triple World Champion, Freddie Spencer, was presented by many in the media as a devout Christian who hailed from the Bible belt town of Shreveport Louisiana USA. It was alleged his faith helped him to his first 500cc World Championship in 1983 defeating “King” Kenny Roberts by just two points. The truth though is somewhat different.

Freddie Spencer’s autobiography (with Rick Broadbent) is an openly disarming account of his life. From the early days racing with his Dad, Frederick Snr, to the highs and the lows of his racing career and the many injuries he sustained but hid from the press. Freddie reveals that he was not a churchgoer or deeply religious, but he has faith and his journey has been in many ways a spiritual one.

Spencer is also the only rider to have won both the 250cc (Moto2) and 500cc (MotoGP) World Championship in the same season, a feat that is unlikely to be emulated. FEEL: My Story, is the book that fills in the blanks surrounding Freddie’s career and reveals a fascinating insight into his search for meaning.

Highly recommended.

Archives: The Great Wings and Wheels Challenge

Jeff Evans aboard his 1950 Norton International and Neville Schubert on his 1956 MSS Velocette take on the Supermarine Spitfire MK V111 (background) in the feature event.

The classic racing scene has become a worldwide phenomenon over the past thirty years or more.  The highly successful Goodwood Festival of Speed was first held in 1993 followed five years later in 1998 by the Goodwood Revival that celebrates not only historic racing cars and motorcycles but also aircraft with spectators dressing in period costume to recreate the era.

1993 was also the year Adelaide had its own unique historic event in aid of charity. Below is my report on the meeting.

*                            *                               *                           *

The idea for the Great Wings and Wheels Challenge was inspired by the writings of T.E. Lawrence – the fabled “Lawrence of Arabia “. It was Airman Lawrence’s exploits racing his “super tuned” Brough Superior SS100 motorcycle against the likes of World War One aircraft such as Bristol fighters and Sopwith Camels that captured the imagination of Blind Welfare fundraising promotions officer, and motorcycle racing enthusiast, Chris Wain.

With the help of the Historic Motorcycle Racing Register, Tourism S.A., the Historic Racing Register and the Federal Airports Authority, this unique event was put together to aid the Blind Welfare Association by pitting historic motorcycles, cars and aircraft against each other.

Held in absolutely perfect weather conditions on Sunday, November the 14th at Adelaide’s Parafield Airport, the organisers turned on an entertaining family event that was enjoyed by approximately 20,000 spectators.

But how do you translate Lawrence’s daring races on public roads into an event contained within the safety conscious confines of Parafield Airport? The answer turned out to be really quite simple. By utilising three of the northwestern runways it was possible to have the motorcycles, cars and aircraft race each other side by side over a measured four hundred metres.

Kent Patrick’s magnificent Type 37A Bugatti.

In the spirit of the era, well known “flagman”, Glen Dix, waved them away with each competitor’s progress being timed by hand held stopwatch. With some sixty entrants in the car division and thirty-five in the motorcycle class, it was going to be quite a feat to get through the various categories before a final “top ten shootout” for the three divisions could be held. Each competitor though was guaranteed at least three runs, with their best time to be recorded on a special certificate and accompanied by a plaque.

The air was filled with nostalgia as the time trials started with interesting machines for both motorcycle and car enthusiasts to watch and aircraft aficionados to admire. In the motorcycle class, these ranged from Doug Treager’s 1961 Manx Norton and Dean Watson’s 1948 KSS Velocette to Mark Schuppan’s 1962 pan head Harley Davidson outfit. The sight of Peter Graham’s vintage 4.5 litre Bentley and Kent Patrick’s Type 37A Bugatti whipped up images of Le Mans and Brooklands in the car class, which added to the atmosphere of the occasion, helped along with such classics as the SS100 (Jaguar) of Simon Finch and Don Davies MG TC special.

Colin Pay taxies his Supermarine Spitfire MK V111.

The aircraft were well represented too, including perhaps that most loved of bi-planes the Tiger Moth owned by Bryan Price and also the Boeing Stearman’s of Ivor Peaech and Tim Knappstein.

The time trials, however, were not the only attraction of the event. The organisers had made sure there was a carnival atmosphere with plenty of side shows, rides and static displays to admire. The latter included public access to the cockpit of an Avon Sabre jet fighter of the type used during the Korean War.The Southern Cross Trust also had on display their replica of the Focker V11 that carried Australian pilot Charles Kingsford Smith on the first aerial crossing of the Pacific from America to Australia in 1928.

But the stars of the show for most were Colin Pay’s World War Two Supermarine Spitfire Mark V111 and the Hawker Sea Fury owned by Guido Zuccoli. It was the individual lunchtime acrobatics of these two aircraft that had the crowd enthralled. If the Spitfire could be described as swift agile and elegant, then the Sea Fury was fast furious and loud. With 2,550hp on tap from its radial 18 cylinder engine, the Sea Fury is one of the most powerful piston engine aircraft ever built, and after seeing it in action there are few who would dispute this claim. Truly awe inspiring stuff and a fitting build up to the feature event of the day – a match race between a Brough Superior, the Supermarine Spitfire and a Type 37A Bugatti.

Time trials winner Andy McDonald on his 650cc Triton (15) lines up against Bob Eldridge on his Honda CB72 based racer.

Unfortunately, this brought the only disappointment of the meeting when the Brough Superior was unexpectedly scratched. Neville Schubert’s 1956 MSS Veloccette and Jeff Evans 1950 600cc Norton International however ably filled its place. To the entertainment of the crowd, these classic and vintage competitors lined up against each other in a cacophony of revving engines as they waited to be flagged away. At the starter’s signal, they launched themselves off the line with the motorcycles scrambling to an immediate advantage, which they held to the line. The Spitfire, although putting in a creditable 17.38 seconds run, was no match, but it was still quick enough to beat home the vintage Bugatti.

By now most of the huge crowd were suffering from a severe case of nostalgia overload as the meeting started to wind down with the final runs of the top ten entrants being run for each class – although it would be the fastest run the competitors had accomplished on the day that would decide the winner of the time trials.

The most powerful piston engined aeroplane in the world the Hawker Sea Fury.

And they were pretty close too, with eight competitors getting into the 13 second bracket in the motorcycle category and two in the car class. The overall winner and first in the motorcycle division went to Andy McDonald on his 1962 650cc Triton with a 13.04sec pass. Overall second and first in the car class was the Elfin of F. Greeneklee with a 13.12sec run while third place and second in the motorcycle category went to Wal Morgan on his 1962 650cc Tribsa with a time of 13.25sec.

Worth a mention also is the effort of Neil Munro and Shane Edwards who came sixth overall with a13.47sec on their 1000cc Vincent HRD outfit. Perhaps not surprisingly the aircraft didn’t fare so well, with the best time of 16.0sec being achieved by Tim Knappstein with his Boeing Stearman.

But the real winners, of course, were the public who got a unique opportunity to see some amazing machinery compete against each other and in doing so contribute toward a very worthwhile cause.

Vale Nicholas Patrick Hayden

 

2006 MotoGP World Champion Nicky Hayden has passed away following an incident with a car while out training on his bicycle along the Riviera di Rimini on the Adriatic coast. He had competed at the nearby Imola circuit the previous weekend in the World Superbike Championship. On Wednesday the 17th of May he sustained severe head and chest injuries when he was hit by the car.  Hayden was treated at the Maurizio Bufalini Hospital in Cesena. “The medical team has verified the death of the patient Nicholas Patrick Hayden, who has been undergoing care in the intensive care unit following a very serious polytrauma, ” the hospital said in a statement.

The 35-year-old from Owensboro Kentucky started out racing dirt track in his native USA before switching to the tarmac and was crowned AMA Supersport Champion in 1999.  This was followed by the AMA Superbike crown in 2002 making Hayden the youngest rider to win the title before moving to the MotoGP World Championship for 2003. As a rookie, he took two podiums that year, at Motegi in Japan and Phillip Island in Australia.  More podiums followed in 2004 before Hayden took his first pole and Grand Prix victory at Laguna Seca in 2005. The following year, the “Kentucky Kid” became the MotoGP World Champion beating Valentino Rossi to the premier class crown, only securing the title at the last round of the year at Valencia in Spain.

Statement from Tommy Hayden, on behalf of the Hayden family:

“On behalf of the whole Hayden family and Nicky’s fiancée Jackie I would like to thank everyone for their messages of support – it has been a great comfort to us all knowing that Nicky has touched so many people’s lives in such a positive way.

“Although this is obviously a sad time, we would like everyone to remember Nicky at his happiest – riding a motorcycle. He dreamed as a kid of being a pro rider and not only achieved that but also managed to reach the pinnacle of his chosen sport in becoming World Champion. We are all so proud of that.

“Apart from these ‘public’ memories, we will also have many great and happy memories of Nicky at home in Kentucky, in the heart of the family. We will all miss him terribly.

“It is also important for us to thank all the hospital staff for their incredible support – they have been very kind. With the further support of the authorities in the coming days, we hope to have Nicky home soon.”

Archives: A Special Classic Racer

 

From humble 250cc road going street bike to 500cc championship winning classic racer.

I penned this article in 1984 for Bike Australia, and over the thirty years since, Jerry Kooistra built Honda CB72 based 350cc and 500cc classic racers have been winning championships and breaking lap records.

Classic racing in Australia has become one of the most popular and fast growing sections of motorcycle road racing, a trend that’s also sweeping many other parts of the world. The class in Australia caters for motorcycles manufactured between 1931 to 1962, giving a new lease of life to many famous, but previously idle, racing machines. It has also lured former world and national champions out of retirement to compete; recreating an era of motorcycle racing that was missed by many of today’s racing enthusiasts.

At any classic meeting, it’s not unusual to see pristine examples of pure classic racing machinery such as the 500cc Manx Norton or 350cc 7R AJS. However, it is unusual to find a Concours condition racing special built from a road bike that would do any factory’s racing department proud. The racing bike in question is the Graham Besson and Jerry Kooistra owned and built Honda 500cc twin that started its life as a road going 1962 250cc CB72 Super Sport.

The 500cc and its older 350cc brother have made the team a force to be reckoned with in Australian classic racing. The teams racing debut was at the September 1981 classic meeting in South Australia. Using the 350cc CB72 they won all four heats against machines of up to 1000cc capacity and in the process broke the lap record. Since that successful debut, the 500cc version has been developed and holds lap records at all four venues in South Australia and recently won the 1983 Historic Twin Cylinder Championships at Mallala Motorsport Park.

Graham and Jerry modestly suggest this is due to their professional approach to racing that has been complimented by having top riders such as Wayne Gardner and former Australian Champions Otto Mueller and Bill Horsman riding their machinery. The team has been so encouraged by their results that they’re building a new 500cc bike for Bill Horsman to ride at Daytona in the Classic Race and Battle of the Twins. The target is Daytona 1985 due to business commitments and the need to find sponsorship to fund the project.

But success for the CB72 racers did not happen overnight and it has taken many years of development to make them competitive racers. Graham started modifying Honda CB72’s with mechanic and racer Terry Dennehey back in the early sixties when Besson was a budding road racer living in Sydney. Their bike in 350cc form was officially timed at 136mph (223kph) at Longford in Tasmania, which Graham believes is still the record for a 350cc four-stroke. In 1970 with the motor stretched to 500cc, it was measured at 142mph (228kph) at Bathurst.

It’s worth noting that “Pops” Yoshimura (who was virtually unknown outside of Japan at that time) was developing the CB72 engine along the same lines.   A data sheet put out by Yoshimura and distributed by Honda compared favourably with Besson and Dennehey’s development work. Eventually, Graham pulled out of the project and Dennehey sold the bike to the Honda Racing Team of Tasmania who Kooistra was involved with as a rider/mechanic. Graham later moved to South Australia with his family, which by chance is where Jerry Kooistra moved some years later. It was after meeting again that they decided to build the current generation of CB72 racers to meet classic racing requirements as a “hobby”.

To say their CB72 racer is highly modified would be something of an understatement and would probably not do justice to the many parts that Jerry Kooistra (who is a toolmaker by trade) has fabricated for the bikes. On the 500cc engine, they’ve used their own specially built crankshaft to increase the engine’s stroke from 54mm to 64.8mm, which required the use of a spacer between the barrels and the crankcase. The bore has been increased from a humble 54mm to a whopping 70mm by using new liners. These took so much “meat” out of the barrels that the cooling fins had to be welded together! Many hours were spent optimising the cylinder heads gas flow with the resultant increase in inlet and exhaust valve size of 27mm to 32mm and 32mm to 37mm respectively. Compression has also gone up from 9.5:1 to 10.5:1.

Although Graham developed a lumpier camshaft for the CB72 in the sixties, they have found it necessary to design a new profile for the special requirements of the bigger engines. Jerry has also slotted the camshaft sprocket and can adjust the degree of cam timing independent of the crankshaft and individually for each cylinder. Kooistra will even grind the cam followers in the quest for a perfect set-up. The original neoprene guides for the cam-chain have been retired so that steel items can be used in the pursuit of reliability.

A pair of 31mm Keihins, that replace the standard 22mm units, supply the air-fuel mixture. These were acquired from the Honda Racing Services Centre and were at one time offered as part of a race kit for the CB72. They are replicas of the carburettors on the factory’s first 125cc Grand Prix racers from 1959 except they are die-cast instead of sand-cast. All that effort to get more air-fuel into the combustion chamber to create a bigger “bang” would be partially lost if the exhaust system didn’t allow the engine to exhale properly. Over a hundred hours were spent developing exhaust megaphones to achieve the correct power characteristics only to find the exhaust note was over the allowed decibel limit. In desperation, some mufflers were made from automatic transmission parts and tacked on the end the megaphones. To their surprise not only did the mufflers put the exhaust noise under the decibel limit but also increased the racers horsepower. Jerry believes the engine is making approximately 60bhp at 10,000rpm, a jump of 36bhp over the stock 250cc engine that produced 24bhp at 9,000rpm.

Lengthening the stroke of the engine required some special thought to increase the oil supply and to improve crankcase breathing. The standard 250cc CB72 sump was small capacity and only carried 1.4 litres of oil so an extra oil tank was fitted directly above the crankshaft relieving oil pressure and allowing it to flow back into the crankcases. Breather hoses run from this tank to a catch-tank which doubles as the seat bum-stop. A VW oil cooler is also fitted under the engine to utilise cool air scooped up by a lip in the fairing.

The ignition has been modified from the usual battery coil set-up to a more suitable magneto system, which Kooistra made. With the increased torque of the 500cc motor, the primary drive chain was seen as a possible weak link due to difficulties experienced earlier with the 350cc engine. Jerry attacked this problem by replacing the chain with his own gear drive system between the crankshaft and the clutch, resulting in a totally reliable primary drive. Problems did occur with the race kits $1,200 five-speed transmission. The five-speed racing transmission was designed to fit in the space vacated by the standard four-speed gearbox and was designed to handle only 28 fairly tame racing horsepower. Unfortunately, the full torque of the 500cc engine at 9,000rpm usually resulted in stripped gears. One solution was to increase the speed of the gearbox to the crankshaft by changing the gear ratio between them. The other was to change to a cush gear drive by installing a Honda dream rear hub, the both of which have eradicated the gearbox woes. The clutch has also been beefed up with the addition of three more plates making a total of eight.

No matter how much horsepower is extricated from a racing engine that alone will not win races. A lot of innovation and clear thinking has gone into transforming the CB72 from an adequate road bike into an excellent racetrack performer. The CB72 is well known for dragging its engine cases under racing conditions which can result in oil leaking from the main oil feed gallery that runs to the gearbox on the primary side. To improve ground clearance the spine tube type frame was cut into half a dozen pieces and then reassembled with extra bracing around the main backbone tube and the standard length swingarm. The opportunity was also taken to change the steering heads rake and trail to angles more suited to racing.

The net result is an extremely rigid frame with more ground clearance than available tread. The front forks are standard items with the main development being different weight fork oil. Earlier experience with the race kits stiff fork springs only resulted in producing the world’s first 140mph (225kph) pogo stick! At the rear Koni hydraulic shocks are used but re-valved by Jerry to his specification.

Some problems were encountered with the standard twin leading shoe front brake that under racing conditions were cracking the hub due to excessive heat build-up. The solution to this came in the form of a specially cast hub Graham had made by his father-in-law in the early sixties. A new hub was made from the pattern of the original to give the bike a twin leading shoe arrangement. But it wasn’t quite as simple as it sounds. To get identical brakes on each side Jerry took the backing plate of a CB72 front brake and cut it into seven pieces. He then re-arranged the pieces so he had a mirror image of the original and welded them together. It’s almost impossible to detect the welds as the whole thing is so well executed it looks like a factory component.

A Honda Dream rear brake unit with competition linings adequately handles the rear braking duties. Kooistra also crafted the tank and seat unit from aluminium as well as the fairing of their first bike, the 350, from which fibreglass replicas were moulded. Jerry’s five-year cadetship in mechanical instrument and tool making shines through again in the execution of the hollow footpegs, brake and gear lever, which have an almost clinical precision to them. The overall effect of this high level of craftsmanship is a racer that looks as though it just rolled out of the factory’s racing department and good enough to win the Best Competition Bike and Best Bike trophy at the 1983 Adelaide M.R.A. Bike Show.

Note the replica carburettor patterned on the Grand Prix units used by Honda in 1959.

To Graham Besson, the Honda CB72 based racers are a realisation of how he would like to have gone racing 20 years ago. For Jerry Kooistra, they have been an outlet for an inquisitive mind and an enormous creative talent. With 8 times Australian Champion, Bill Horsman, riding them you have an irresistible force in Australian Classic Racing that with the required sponsorship can only do well at Daytona in 1985.
