Many-times British sidecar champion Colin Seeley bought Associated Motor Cycles' racing department when the company went into receivership in 1966. Seeley's motorcycle dealership possessed an AMC agency and he was already well familiar with the Plumstead firm's race engines, having commenced his sidecar racing career with a G50-powered outfit. Believing that the engines possessed further potential if equipped with state-of-the-art cycle parts, 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, Derek Minter winning first time out at the start of the 1966 season on both the 350cc 7R and 500cc G50-engined Seeleys. The Seeley frame progressed from the duplex cradle MkI to the similar but lighter MkII on which works rider Dave Croxford won the British 500 Championship in 1968. The down-tubes were abandoned with the MkIII, the headstock and swinging arm pivot of which were linked solely by tubes running diagonally above the engine. Supported by sponsor Gus Kuhn, Seeley-mounted Croxford triumphed again in the British 500 Championship in 1969. The Seeley MkIV introduced towards the end of 1970 featured a revised tubing layout and continued in production until 1973, achieving further successes. Production of Seeley frames was later licensed to Roger Titchmarsh and there have been countless unauthorised copies made over the years.

This Seeley G50 replica was built for Alan by Roger Titchmarsh in 1998 (bill on file). The Mick Taberer engine incorporates a Newby crankshaft, titanium con-rod, Omega forged piston, coil valve springs, and a Nikasil-plated aluminium cylinder liner. Other notable features of this well developed machine include a Gardner carburettor, Maxton front fork, Maxton rear dampers, a Hemmings five-speed gearbox, and total-loss ignition. Alan raced the Seeley in IHRO events and it has been paraded by his friend, the late Colin Seeley, Leon Haslam and Dave Croxford. Showing that he had lost none of his speed, Croxford returned the Seeley to the paddock with its fairing scuffed on both sides! Re-commissioning to a greater or lesser extent will be required before the Seeley returns to the racetrack. The machine is offered with a selection of colour action photographs and some bills. It should be noted that Alan has owned more than one G50-engined motorcycle over the years and it cannot be determined whether or not all these bills belong with this particular example (some appear to relate to another Seeley G50 built for Geoff Sawyer).
