1967 bsa c25 barracuda
C25 Barracuda / B25 Starfire 1966-1970, 249cc, ohv single, 330lb, 60mpg, 75mph. Restyled C15 to try and keep up with the times. Tougher internals and castings, but less reliable due to the high compression engine, big-end problems being the most likely. The B25 Starfire introduced in 1968 is a better bet as it was more reliable and had less vibration following a mild de-tuning. Also sold as the Fleetstar for fleet users which was a de-tuned version which gives more reliability and in a modified frame.
