AJS Model S3 1931

At the time of its introduction in April 1931, the AJS S3 was in a class of its own, being the only transverse v-twin engined model on the UK market. The S3’s air-cooled v-twin motor carried its cylinders at an included angle of 50 degrees; side valves were operated by two chain-driven camshafts and the three-speed gearbox incorporated a spiral-bevel, right angle drive to the enclosed rear chain.
