Lot 373: 1962 AJS 349cc 7R Racing Motorcycle
Built from 1948 to 1963, Associated Motor Cycles’ AJS 7R - known as the ‘Boy Racer’ - was one of the most successful over-the-counter racing motorcycles of all time. Almost all Britain’s road-race stars of the 1950s and 1960s rode a 7R at some stage of their careers, and the model remains a major force in classic racing today. Although a new design by Phil Walker, the 7R with its chain-driven overhead camshaft was very reminiscent of the AJS ‘cammy’ singles of pre-war days. While - initially - not as powerful as the Velocette KTT and Junior Manx Norton, the 7R’s robust and simple construction endeared it to the privateer responsible for his own maintenance. While the duplex loop frame and Teledraulic front fork remained essentially unchanged throughout production, the engine underwent almost continuous revision: the valve angle being progressively narrowed, the crankshaft made stronger and, in 1956, engine dimensions changed from the original long-stroke 74 x 90mm to the ‘squarer’ 75.5 x 78mm that permitted a higher rev limit. AMC’s own gearbox replaced the previous Burman in 1958, while engine development continued almost to the end of production, by which time the 7R was putting out around 41bhp. Offered for restoration, this incomplete AJS 7R comes with exhaust system and Amal GP carburettor (body only).
