The Triumph TR25W Trophy was a 250-cc OHV engine based on the BSA B25 Starfire and designed for the trails. Although the engine and frame were very much BSA, Triumph improved the ride by adding larger wheels, modified gearing, and upswept exhaust to better suit the off-road styling.

The TR25W Trophy on offer presents very well in Cherry red paint and would make a great trail bike or road bike after some reconditioning.
