Associated Motor Cycles returned to the 250cc class in 1958 with a brace of all-new models.

Shared by the AJS Model 14 and Matchless G2, the overhead-valve power unit incorporated its oil tank within the crankcase and appeared to be of unitary construction, although a separate gearbox was retained. The conventional cycle parts comprised an open, tubular steel frame, closed at the bottom by a pressed-steel channel, complemented by a telescopic front fork and swinging-arm rear suspension.

AMC had ended production of standard, sports and scrambles versions by July 1963, while the CSR super-sports models lasted until 1966.
