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. 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. Despite the fact that the 7R was not, initially, as powerful as its main rivals - the Velocette KTT and Junior Manx Norton – its robust and simple construction endeared the model 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 74x81mm bore/stroke to the 'squarer' 75.5x78mm, permitting higher revs. 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.
This 'barn find' AJS 7R was acquired from the vendor's late father-in-law circa 40 years ago and was last used around 20 years ago. Apparently complete, the machine is offered for restoration and sold strictly as viewed (close inspection advised). There are no documents with this Lot.
