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.
