Registration no. RTT 446
Frame no. CA7 4979
Engine no. CA10 3019

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.

The example offered here has belonged to the late owner since 1994. Restored by him in 2000, the Golden Flash comes with a most extensive history file documenting the restoration in full (perusal recommended). Now nicely patinated, the machine would respond well to detailing. Careful re-commissioning and the customary safety checks are advised before further use. Offered with a V5C document.
