Property of a deceased's estate
1960 BSA 649cc A10
Registration no. VFU 422
Frame no. GA7.6199
Engine no. DA10 10213

A new '650' twin joined BSA's 500cc A7 model in 1949. The existing parallel twin architecture was retained for the new A10, with 360-degree crankshaft and single camshaft at the rear of the cylinder block, as was the four-speed gearbox bolted directly to the crankcase in a form of semi-unitary construction. Like the A7, the A10 was available initially with either a rigid frame or plunger rear suspension. Named 'Golden Flash', the new 650 was strikingly finished in pale beige metallic. Ever since the model's introduction enthusiasts have commonly referred to the touring A10 as the 'Golden Flash', even when it was finished in alternative colour schemes, as seen here.

BSA's rugged 650cc twin had undergone considerable development by the end of the 1950s. 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 had benefited from numerous improvements including an increase in compression ratio for 1958 and the standardisation of the sports models' high-lift camshaft for 1959.

The current vendor's late father acquired this A10 in 2019. A self-employed gas turbine engineer. Motorcycles were his passion and had been from a young age.
Sadly, no other history is known about this A10. Following a period of inactivity, the machine will require recommissioning to a greater or lesser extent and thus is sold strictly as viewed. Offered with a current V5C.
