BSA's rugged, workaday B31 was manufactured from 1945 to the end of 1959, its overhead-valve engine providing the basis for the renowned Gold Star sports roadster. In January 1946 it was joined by a Competition variant, the B32, which boasted a high-level exhaust system, 21" front wheel, additional chromium plating, a crankcase shield and lowered gearing. An alloy cylinder barrel and head, broadly similar to those used on the contemporary Gold Star but retaining a separate pushrod tunnel, became available as B32 options from 1949 onwards, as did plunger rear suspension in common with the rest of the 'B' singles range. From January 1947 there had been a similar 500cc model - the B33 - in the roadster range, and in April of that same year the B34 competition version, essentially the same as the B32 apart from the larger engine and changes to the gearing, made its debut. Production ceased in 1957.
First registered on 16th March 1950, this B34 has belonged to the vendor since 2000 and has been used regularly for VMCC rallies, winning numerous awards. We are advised that the magneto has been rebuilt and that the machine is believed to be pretty much to factory specification. Offered with a V5C document.
