A new '650' 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-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.
This pristine A10 is offered for sale fresh from a 'ground upwards' restoration and has not been run since the rebuild's completion. We are advised that refurbishment carried out included a re-bore and new pistons; reground crankshaft with undersized timing-side bush; new wiring loom; rebuilt dynamo with new armature; new electrical switches, etc. It is also worthwhile noting that the original Dunlop wheel rims have been retained. All fluids should be checked before any attempt is made to start the machine. NOVA will have been completed by time of sale.
