The Matchless G12 was one of the last motorcycles designed under the Matchless name. It was also produced as the AJS Model 31 by the same company. Designed by Phil Walker, AMC knew that it had to be a 650cc (39. 7 cu in) but wanted to use as many parts from the Model 11 as possible. The cylinders could not be bored out further so the stroke was lengthened from 72. 8 to 79. 3 mm (2. 87 to 3. 12 in), resulting in a capacity of 646cc (39. 4 cu in). This meant developing a new crankshaft and primary chaincase, which also provided the opportunity to add a Lucas alternator. Volume production began in September 1958.
This bike has come from a local collector who has maintained it at a very high standard. It is in full working order and comes with full V5, owner’s and workshop manuals and some other paperwork relating to this model of bike.
