A top-selling model for BSA in the 1920s, the versatile Model B, or ‘Round Tank’, was used by just about every tradesman whose job required cheap personal transport. Popular with learners - the fact that the gearbox had only two speeds and that both brakes operated on the rear wheel were attributes guaranteed to re-assure novices - the reliable 250 sidevalve provided many with their first motorcycling experience.

Advanced features, for a lightweight, included all-chain drive and pumped lubrication, though the traditional sight feed and auxiliary hand pump were retained. In 1926 a three-speed version - identifiable by its black tank - was added to the range. Reverting to BSA’s traditional green finish the following year, the Model B was available in three-speed form only, although there were now two versions: ‘standard’ and ‘de Luxe’, the latter boasting a wedge-shaped tank.

Marginally heavier and slightly more expensive, the de Luxe was the only Model B offered in 1928.
