One owner since 1973
1971 Seeley 496cc G50 MkIV
Frame no. Mk4CS213
Many-times British sidecar champion Colin Seeley bought Associated Motor Cycles' racing department when the company went into receivership in 1966. The previous year he had constructed the first Seeley racing frame to house a Matchless G50 engine, and the AMC purchase enabled him to produce complete Seeley G50 and 7R machines. With their improved frames, the four-stroke singles enjoyed renewed competitiveness, Dave Croxford winning the British 500 Championship on a Seeley G50 in 1968 and '69.

A MkIV model to 1972 specification, this example was sold new by Colin Seeley to Dutch rider Henk Coeman in December 1971. Coeman raced the Seeley for one year then part-exchanged it for a Konig at Monty & Ward, from whom the present owner purchased the machine on 1st August 1973. It was ridden in the Senior Manx Grand Prix in 1973, '76, '77, and '78; at the Brighton Speed Trials in 1979 and '80; at the Hoghton Towers sprint in 1981 and '82; at the Isle of Man TT 75th Anniversary parade in 1982 and the Senior Classic Manx Grand Prix in 1983. The oil was drained immediately after the latter event, since when the motorcycle has been carefully stored and its engine turned over regularly. The machine is in completely original condition - even down to the fairing and seat unit - the following common and easily reversed modifications excepted: coil ignition changed to Lucas 2MTT racing magneto, Triumph oil pump changed to AMC G50 type, bolt-on steering damper fitted and primary chain oil catch tank installed. Presented in good condition throughout, the machine has the five-speed PGT gearbox and is finished in silver, red and blue. Assorted alternative rear wheel sprockets, a spare megaphone and two side-stands accompany the machine. A possibly once-in-a-lifetime opportunity to acquire an exceptionally original example of the last great British four-stroke racing motorcycle of the classic era, offered from careful long-term ownership.
