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.
