1958 Ariel FH650 Huntmaster

In 1944 the firm was sold to BSA. After the sale, Ariel built two types of twins, the softly-tuned 500cc KH, which debuted in 1949 selling poorly, and the more powerful and successful Huntmaster which was powered by a modified version of the 650cc engine from BSA's A10. The Huntmaster however was it's own bike with a completely different frame from the A10. The Huntmaster was particularly popular with sidecar fanatics in the late 1950s.
