Gregory John "Gregg" Hansford (8 April 1952 – 5 March 1995)
After his international motorcycle racing career ended prematurely in 1981 due to serious injuries from a racing accident, Hansford returned to Australia and established himself as a competitive driver in Australian touring car competitions. Hansford's 1993
Motorcycle racing career
Early Australian racing
Hansford was born in East Brisbane, Queensland, Australia where he attended Milton State School (1958–1960), the Anglican Church Grammar School (1961–1967) and Brisbane State High School (1967–1969).[1] He worked as a motorcycle mechanic and began racing motorcycles in 1971 with financial assistance from his mother.[1][4]
He began competitive motorcycle racing in dirt track racing and then motocross, before focusing on road racing in the early 1970s.[5] John Taylor at Brisk Sales supported his early road racing career by offering him the opportunity to race a Kawasaki H1R, which led to an offer to race for the Brisbane Yamaha distributor, Annand and Thompson.[5] He became known for his mastery of the Lakeside International Raceway, his home circuit near Brisbane.[4]
In 1974 Yamaha introduced the TZ750 which would dominate the 750cc class during the 1970s.[6] The Annand and Thompson-Yamaha team obtained one of the newly-released machines on which Hansford made his international racing debut at the 1974 Daytona 200, then considered one of the most prestigious motorcycle races in the world.[7] However, during the race the motorcycle experienced ignition problems and he failed to finish.[8]
Hansford returned to Australia where his battle with Warren Willing in the 1974 Unlimited Class Grand Prix at the Mount Panorama Circuit has been cited as one of the greatest Australian motorcycle races of the 1970s.[3][5][8] Both competitors rode similar Yamaha TZ750s in an event that featured numerous lead changes throughout the 20 lap race, before Willing took the victory over Hansford by a narrow margin.[1][5] Despite losing the Mount Panorama round, Hansford prevailed to win the 1974 Unlimited Class Australian national championship at the age of 21.[9] The victory marked the first of six Australian motorcycle road racing National Championships in different classes that he won during his motorcycle racing career.[4]
Kawasaki sponsorship
In 1975, Hansford was contracted by
Hansford returned to the Daytona 200 in 1977, where despite the domination of the 750cc class by the Yamaha TZ750, he posted a credible fourth place result as the highest-placed Kawasaki rider.[5][10] Hansford’s KR750 lacked the power to compete with the Yamaha TZ750, but he made up the deficit with sheer ability.[8] At the 1977 Laguna Seca round of the 750cc AMA National Championship divided into two heat races, he scored second and third place finishes, then defeated veteran Gary Nixon in a race long battle to win the 250cc class.[5][11] At the Canadian round of the 1977 FIM Formula 750 Championship held at the Mosport Circuit on September 18, Hansford beat Yvon Duhamel and eventual Formula 750 champion, Steve Baker for the victory.[12]
Hansford's international results were so impressive that, the annual motorsports publication, Motocourse, rated him as the number five rider in the world, despite the fact that he had never ridden in an FIM World Championship Grand Prix race.[3]
World Championships
Hansford moved up to the 1978 Grand Prix World Championships as part of the Team Kawasaki Australia effort that consisted of the Kawasaki KR250 and KR350 as well as the KR750, with Hansford as the rider and Neville Doyle as manager and mechanic.[8] Their plan was to contest the world 250cc and 350cc world championships and, whatever Formula 750 events that their schedule allowed.[3]
Hansford would face a field of rivals who mostly competed on privateer Yamaha TZ 250s and TZ 350s, but his most significant rival was South African, Kork Ballington, riding similar Kawasaki KRs supported by Kawasaki’s British importer.[5] Ballington's small physique gave him an advantage over the larger and heavier Hansford, who stood over 6 ft 0 in (1.83 m).[5][8] Not only did this give Ballington a power-to-weight advantage, his small physique also gave him an aerodynamic advantage by allowing him to tuck his body behind his motorcycle's windscreen, while Hansford's limbs protruded beyond his windscreen.[5][8]
In his world championship debut at the 1978 Venezuelan Grand Prix, Hansford suffered a poor start in the 350cc race and was outside of the top twenty after the first lap. He recovered in an impressive manner to take the race lead after four laps and had a three-quarter lap lead over the opposition when his motorcycle had a mechanical failure.[8] He also dropped out of the 250cc Grand Prix with mechanical problems while holding third place.[8]
At the following 1978 Spanish Grand Prix, Hansford was initially denied an entry by Spanish race organizers who claimed that he was not on the official FIM grading list.[8] As Hansford had withdrawn from the previous Grand Prix in Venezuela without a result, Spanish race organizers claimed to have no record of Hansford's previous 250cc class experience.[8] Eventually the FIM relented and Hansford was allowed to race, but with only one qualifying session left.[8] Hansford posted a qualifying time 0.1 seconds behind pole sitter, Kenny Roberts, then won the race over Roberts to claim his maiden Grand Prix victory.[8]
At the 1978 French Grand Prix, Hansford won both the 250cc and 350cc classes, the first of three 250/350 double victories in 1978.[2] Ballington beat Hansford by a half a wheel in the 250cc Nations Grand Prix at Mugello and both riders were credited with identical race times.[3]
Hansford demonstrated his ability to learn new circuits at the 1978 Swedish Grand Prix where he claimed the pole position for the 350cc class with a faster lap time than Johnny Cecotto posted in the 500cc class.[3] At the German Grand Prix held at the daunting, 14.2 miles (22.9 km) long Nürburgring racetrack, considered too dangerous for the Formula One championship, Hansford was the fastest 250cc and 350cc qualifier, on his first visit to the circuit.[3] Ballington won three of the last five 250cc races to edge out Hansford for the championship by six points.[2] Ballington also claimed the 350cc World Championship, while Yamaha's Takazumi Katayama finished in second by a narrow one point margin over Hansford.[2][3] At the end of the 1978 World Championship season, Hansford had won seven 250cc and 350cc Grand Prix races.[2][3]
After Pat Hennen suffered career-ending injuries while competing in the 1978 Isle of Man TT, the Suzuki factory racing team attempted to replace the American rider during the off-season by offering Hansford a contract to join their team as Barry Sheene's teammate in the 500cc class for the 1979 season.[9] However, Hansford rejected Suzuki's offer, choosing to remain loyal to the Kawasaki team.[9]
Hansford suffered injuries while testing his motorcycle prior to the 1979 season.[8] His injuries and tire problems led to a slow start in which he failed to score any points until the fourth round when he won the 350cc Nations Grand Prix at the Imola Circuit.[8] At mid-season, the team switched from Michelin to the Dunlop tires used by Ballington.[8] Hansford would win three Grand Prix races in 1979, all in the 350cc class.[2] Once again, he finished second in the 250 championship and third in the 350.[2] His victory at the 1979 350cc Finnish Grand Prix marked the final victory of his motorcycle racing career.[2][3] He also rode the KR750 to win the French round of the 1979 Formula 750 championship, held at the Nogaro Circuit.[13]
1979 riders' revolt
During the 1979 season, the riders had boycotted the
Yamaha rider Kenny Roberts began talking to the press about forming a rival racing series to compete against the FIM's monopoly.[17][18] At the end of the 1979 season, Hansford joined Roberts, Barry Sheene and British motorsports journalist, Barry Coleman, in announcing their intention to break away from the FIM and create a rival race series called the World Series, with most of the top Grand Prix racers joining in the revolt.[15] The Yamaha factory then offered Hansford a chance to replace Roberts and compete in 1980 500cc FIM World Championship, however he chose to remain loyal to the rival race series and rejected their offer.[8]
When the rival race series collapsed due to difficulties in securing enough race venues, Yamaha withdrew their offer as Roberts returned as their factory sponsored rider, leaving Hansford without a place on a 500cc class team.[3] Rather than staying in Europe to race in the smaller classes, Hansford chose to return home and raced Kawasaki 250s and 350s in the 1980 Australia national championships, while Kawasaki developed their new KR500 for the FIM 500cc World Championship.[3]
Hansford made only one appearance in the 1980 World Championships at the final round in Germany, where he debuted the new KR500 featuring a monocoque chassis, but retired with a mechanical issue.[8] At the prestigious Suzuka 8 Hours endurance race in 1980, he teamed with Eddie Lawson riding a modified Kawasaki Kz1000 to a second place behind Wes Cooley and Graeme Crosby on a Yoshimura-GS1000.[19]
Belgian Grand Prix accident
The Kawasaki factory launched a full effort in the 1981 500cc World Championship, with Hansford and Ballington riding the KR500.[8] He won the pole position at the Imola 200 pre-season race, but while avoiding slower riders, he hit a damp patch of track and crashed, sustaining a fractured tibia.[3]
Upon his return to racing, he suffered another serious crash at the 1981 Belgian Grand Prix when his front brake disc calipers had been improperly replaced.[8] When the brakes failed, Hansford entered an escape road used as an emergency run-off area and managed to slow the motorcycle to approximately 70 km/h with the rear brake, before hitting a car illegally parked by a track marshal.[8] The accident broke the same femur that had been injured at Imola.[8] More serious problems developed from blood clots in his thigh and it would take several years to recover, forcing Hansford's retirement from motorcycle racing.[3]
Hansford returned to Australia where he owned motorcycle dealerships in Brisbane and a personal watercraft shop on the Gold Coast. He continued to develop his businesses however, he was compelled by his competitive nature to announce that he would pursue an auto racing career.[1][5]

Hansford's first touring car race was in the second Moffat
Hansford's first touring car win was the 1984
Later the pair finished second in the Mazda at the Castrol 500 at Sandown before they went on to finish third at the 1984 James Hardie 1000 at Bathurst.[25][26] The Moffat team entered two cars for the race with Hansford listed in both cars alongside Moffat. Hansford won a number of fans by qualifying his RX-7 in 8th place and it was his car (which the team admitted was not meant to run the full race) that crossed the line 3rd after Moffat's own car had been retired with overheating on lap 15.
After Australian touring car racing changed from the locally developed Group C rules to the international Group A rules in 1985, Hansford was forced to look elsewhere as Mazda (nor Moffat for the season) wouldn't be competing. Though at the start of 1985, the Moffat team took their Mazda RX-7, along with Peter McLeod and Kevin Bartlett to drive in the 24 Hours of Daytona. After Moffat qualified the car 38th in the GT class, they progressed through to the top 5 in their class before engine problems saw them drop back to 24th outright at the end of the race.[27]
Hansford then teamed with Moffat's former teammate Colin Bond to drive an Alfa Romeo GTV6 to eighth outright and first in Class B in the 1985 James Hardie 1000.[28] The following year he joined fellow Queenslander Dick Johnson in a Ford Mustang GT and finished the 1986 James Hardie 1000 in fourth outright.
Hansford stayed with
Hansford was told by Dick Johnson at that year's Jack Newton Celebrity Pro-Am that he won't be driving for DJR in the 1988 Australian Touring Car season and was replaced with former dual
Hansford would drive the RS500 Sierras for both Allan Moffat and Glenn Seton Racing in both the ATCC and at Bathurst over the next four seasons, though on-track results would elude him. He finished 2nd at the 1993 James Hardie 12 Hour with Charlie O'Brien in a Mazda RX-7 and won the 1993 Tooheys 1000 at Bathurst with Larry Perkins in a Holden Commodore (VP).[34][35] Hansford's 1993 Bathurst 1000 victory gave him the unique distinction of winning a race at the Mount Panorama Circuit in both motorcycle and car racing.[1][4]
Hansford followed this success with a victory at the
