The BSA C15T was a trials version with a higher clearance frame fitted with a reinforced plate, special gear ratios suited to off-road use and a high level exhaust pipe. A special tank and optional lighting allowed it to be converted for legal road use. The all-alloy engine had a special camshaft, and was specially tuned for off-road trials use. The C15T proved to be competitive at club and national levels, and it remained unchanged in the BSA range until 1965.
