During the 1930s BSA concentrated on producing a range of dependable, well-made, competitively priced motorcycles. When BSA's single-cylinder range was redesigned by Val Page for 1937, the engines took on many of the characteristics they would retain in the post-war era, most notably dry-sump lubrication and gear drive to a rear-mounted magneto. There were three new offerings in the 250 class: the sidevalve B20 and overhead-valve B21 and Empire Star models, the latter featuring foot change as standard on the four-speed gearbox shared with the others. Production of the popular B-Series 250s continued to the decade's end when the range was superseded by the new C-Series quarter-litre models: the C10 and C11.
Its late owner purchased this restored B21 in 2017 but did little with it. Kept in dry storage, the machine is nicely presented, albeit with some loss of paint from the fuel tank. It should be noted that the engine and frame numbers have been re-stamped and that the former does not match that on the V5C. Furthermore, the frame number ('KB21 819') is not correct for a 1939 B21: it should be prefixed either 'KB20' (De Luxe) or 'KJB20' (Standard) and thus it has not proved possible to identify this model with certainty. Accordingly, prospective purchasers must satisfy themselves with regard to this motorcycle's authenticity prior to bidding. Key not required.
