The AJS 7R is a British 350 cc racing motorcycle built from 1948 to 1963 by Associated Motor Cycles. It was also commonly known as the ‘Boy Racer’, and won victories both for the factory and for privateers right from its introduction in 1948. This motorcycle sports the 'long stroke' motor with it's 74 x 81 bore and stroke and has been set up for current AHRMA racing. The motor has undergone a fresh mechanical rebuild although has not been ran in since the rebuild. The motorcycle is set up with alloy wheel rims, fiberglass gas tank, small wind screen and Amal GP carb. The motor has case stamping #1523 so we are not exactly sure what year it actually is. This 7R would be a great addition to any collection or for the vintage race scene.
