Lot 430: BSA A10 'Golden Flash'
A new 650cc A10 twin joined BSA's 500cc A7 model in 1949. The existing parallel twin architecture was retained for the 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 is the case with this particular example, which has covered only 207 miles (approximately 333 kilometres) since restoration in the early 1990s. The machine is offered with copies of various invoices, parts list, purchase receipt (dated 1995) and French Carte Grise normale.
