BSA B40 Gallery

Developed from the unit 250cc C15, the B40 350cc single offered greater flexibility and power output without an increase in weight when compared to the smaller engine. The release of a large number of ex military B40's during the early eighties coincided with a growing interest in Pre 65 trials resulting in many of them being modified to trials specification. The B40 continues to be a favourite in the pre 65 trials world and is well supported by specialist suppliers.
