Lot 1922


1947 BSA B31
Reg. no. OMU 938
Frame no. ZB31 2224
Engine no. XB31 4695
The B31 was the first new model launched by BSA after the end of the war. A 348cc single-cylinder four-stroke bike, it was capable of around 70mph, which was plenty for the roads of the time. It had a rigid frame with telescopic forks – the latter being a first for BSA. Later, plunger rear suspension was available. The B31 proved to be a reliable machine – the engine was under-stressed and strong, and the tried-and-tested pre-war principles on which the bike was built meant that there was nothing too alarming for the home mechanic. As such, it sold well until its replacement in 1959.
This 1947 B31 is in good condition, the only major blemish being a dent on the petrol tank. Restored in 2003, it has clearly been looked after since and is said to run well. It comes with an old logbook and a V5c.
