The creation of one of the British motorcycle industry’s most prolific and talented designers – Val Page – BSA’s new single-cylinder range debuted in 1937. Intended mainly for the sidecar man, the two biggest sidevalve models were the 496cc M20 and 596cc M21, both of which came with rigid frames, girder forks and four-speed, hand-change gearboxes. source/image(PrtSc):
