1950 BSA 650cc A10
Registration no. JCG 61
Frame no. ZA7S 14834
Engine no. ZA10 4783

Introduced late in 1949, BSA's 650cc A10 twin closely followed the basic pattern established by the 500cc A7 while contriving to be almost entirely different in detail. The existing parallel-twin architecture was retained for the new A10, as was the four-speed gearbox bolted directly to the crankcase in a form of semi-unitary construction. The cycle parts remained virtually unchanged, though the larger twin's 8" front brake was one obvious difference. Fitted at first only to export models, the 4.25-gallon fuel tank became available on the home market after one year, as did the striking metallic beige finish of the 'Golden Flash' version. By the end of the succeeding decade, BSA's popular 650cc twin had undergone considerable development. On the cycle parts front, the introduction of a swinging-arm frame in 1954 had resulted in the original bolt-up gearbox's replacement by a conventional separate item, while the engine would undergo numerous improvements before production ceased in 1962.

Dry stored for over 20 years, this A10 will need recommissioning or more extensive restoration before returning to the road and thus is sold strictly as viewed (the engine turns over). The BSA is offered with an RF.60 continuation logbook (issued 1963) showing that it has been in the vendor's family's possession since July 1976. The machine also comes with an old-style V5C and carries a tax disc that expired in February 1972, which is possibly when it was last used.
