The ultimate racing British single: There can only be one, and this special-framed Arter Matchless G50, ridden by legendary rider and engineer Peter Williams and sporting the world’s first cast wheels — designed by Williams himself — must surely be a contender.
Built for the 1970 season, it was the first bike ever to wear cast magnesium alloy wheels, and coupled with its equally ground-breaking use of disc brakes and unique wind-cheating bodywork, Williams’ Arter G50 was a truly avant garde machine whose creation prolonged the competitive life of the 4-stroke single well beyond the advent of the 2-stroke era.
Williams rode the bike to three second-place wins in the Isle of Man Senior TT in 1970, 1971 and 1973, and his 102.74mph singe-cylinder lap record in the 1973 Senior TT stood until 1997.
Arter and Williams
Known as Wagon Wheels, this Arter Special Mk 3 was the crowning achievement of Tom Arter and Peter Williams’ years of racing together. Williams and Arter, a top-rate tuner and race sponsor, first teamed up in 1966, ultimately running a pair of 350/500cc bikes fitted with AJS/Matchless 7R/G50 engines mounted in special Reynolds frames built by master tube bender Ken Sprayson for John Surtees. Surtees never used them because of his move to car racing.
