• Ex-Ted Broad
• Lansdowne and IHRO contestant
• Five-speed gearbox
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, with its robust and simple construction, endeared itself 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 to the 'squarer' 75.5x78mm 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 in 1963, by which time the 7R was putting out around 41bhp.
The 7R offered here was purchased in 2005 from the famous sponsor/entrant Ted Broad, and is believed to be ex-Paddy Driver. Alan bought the AJS to compete in Lansdowne and IHRO events, as evidenced by the numerous scrutineering stickers on the frame and fairing and a selection of colour action photographs on file. For greater reliability the original magnesium crankcases have been replaced with aluminium ones, while other notable features include coil valve springs, Newby belt primary drive, and a Hemmings five-speed gear cluster. The original 'cases, numbered '62 7R 4829B', are included in the sale. Unused for a number of years, the machine will require re-commissioning to a greater or lesser extent before returning to the track. Accompanying documentation consists of a substantial file of bills and the 2005 purchase receipt.
