The History

Former sidecar Grand Prix racer Colin Seeley famed for producing the Matchless G50 and AJS 7R singles in the late 1960s, went on in the 70s to produce Yamaha and Suzuki framed bikes. The Suzuki 500 was campaigned by Barry Sheene with great success.  The frame is almost entirely made from 17 gauge Reynolds 531 tubing with the exception of the head stock and the swinging arm pivot mounting tube which are both CFS3 BK, the end result is a very light weight frame, which handles superbly.
