1949 BSA B31 competition trials, 349cc. Registration number WSJ 507. Frame number ZB32 2151. Engine number ZB32 116.
The B31 was introduced in 1945, it was the first new model introduced by the company after the Second World War. Based on pre-war designs, it used a single cylinder four stroke engine that displaced 348 cc. Initially, it had a rigid frame and telescopic forks, the first use of such on a BSA. There was a competition kit available for the original rigid model B31 and B33. It was immediately popular and was soon joined by a 500 cc version, the BSA B33 and competition equivalents, the BSA B32 and BSA B34.
Little is known of the history of this trials prepared bike, it comes with a bum seat and different gearbox ratios. Running recently, we would always recommend safety checks before road use.
Sold with the V5C.
