Eric Cheney

Cheney's most noted successes were in the Grand Prix road racing championships, with Phil Read using his chassis in tandem with a Yamaha engine to win the 1971 250cc world championship. His designs were the last British ones to win a Grand Prix. He never worked for any of the major manufacturers but maintained a productive relationship with BSA in its heyday. After the demise of BSA in 1972, Cheney joined with former BSA factory rider John Banks to develop and campaign a highly successful BSA powered motocross bike.

Some of Cheney's motorcycle designs are now famous in their own right, such as the competition BSA Gold Stars of Jerry Scott and Keith Hickman and the John Banks replica which used a BSA B50 engine specially tuned by Cheney. He also built some racing frames for Suzuki Grand Prix motorcycles in 1968 and, it has been suggested that Suzuki engineers incorporated features of Cheney's designs, such as magnesium hubs and lower fork legs into production road going motorcycles. Cheney's company was originally known as Eric Cheney Designs, then changed to Inter-Moto, now known as Cheney Racing.

In the late 1960s, the British motorcycle industry was unable to support a national team to compete in the International Six Days Trial so, Cheney hand built a limited number of ISDT Cheney-Triumphs using his own design of twin down-tube frame with a specially tuned Triumph 5TA engine. Fitted with tapered conical hubs, special motocross forks and large alloy fuel tanks, a Cheney Triumph was first used in the 1968 British Trophy Team. In 1970 and 1971 three 504cc Cheney Triumphs were used by the British team in the ISDT, in which Cheney won a manufacturer's prize. Replicas were built, but production was short-lived due to a shortage of engines.

Eric Cheney (5 January 1924 – 30 December 2001) was an English motorcycle racer, designer and independent constructor. He was known as one of the best motorcycle frame designers of his era, concentrating mainly in the off-road competition aftermarket.
