C25 Barracuda (66-67) Starfire (68-70) 249cc ohv single || 330Ib || 60mpg || 75mph || 1966-70

BSA restyled the C15 with a bit more go at the expense of some reliability. Better suspension, lighting and braking were added, and they can be surprisingly charming – and quick-steering, as the later frames were increasingly based around those used on the off-road competition models. Revs like a modern bike; can sound like a bag of spanners. Known for “grenading” their engines. Became the B25 Starfire in 1968, and this is a better bet as it is more reliable and less vibratory following a mild detuning. Also sold as the detuned Fleetstar for fleet users, the last models had 12v electrics, good brakes, and front ends from the middleweight Triumphs, making for a safer ride on modern roads.
