The Kirby BSA sidecar outfit was custom-built as a racing sidecar oufit, specifically designed and developed to compete in the F.I.M. Sidecar World Championship between 1965 and 1973, and built between 1965 and 1966. It was powered by a 654 cc (39.9 cu in) engine from the BSA Spitfire.[1]
The driver, Terry Vinicombe, and passenger John Flaxman were sponsored by Hornchurch, Essex-based motorcycle dealer and farmer Tom Kirby, who also ran a stable of solo racing motorcycles and had promoted Alf Hagon and eventual world champions Mike Hailwood, Phil Read, and Bill Ivy.[3][4]
The outfit won the large-capacity sidecar event at the 1968 Isle of Man TT races.[5][6][7]

British champion Chris Vincent was the early leader of the 750 cc class, but he too was hindered by mechanical gremlins and the Kirby BSA-powered oufit of Terry Vinicombe went on to win.
