Lot 444: 1954 BSA 646cc Golden Flash

Collectors' Motorcycles, Bonhams (16 October 2005)

A new 650cc twin joined BSA’s 500cc A7 model in 1949, the latter’s engine being revised along the lines of the new design at the same time. 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-unit construction) and the tele-fork-and-plunger cycle parts. Named ‘Golden Flash’, the new 650 was strikingly finished in pale beige metallic. The model was up-dated with the swinging-arm frame and separate gearbox for 1955 and continued in production until 1962. Dating from the final year of the A10 in its original form, this superb example has been completely restored to show standard by a professional motorcycle mechanic. Possessing an MoT/road fund licence valid until March 2006, the machine has covered circa 1,500 miles since completion in 2000 and is reported as run in and ‘de-snagged’. Pictures of the machine before restoration are included in the sale together with its original logbook, current Swansea V5, sundry invoices and a detailed list of the work carried out, parts replaced and specialist suppliers used. Although not fitted, the original 1954 rear suspension units come with the machine.
