A new 650cc 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 and the tele-fork-and-plunger cycle parts. Named 'Golden Flash', the new 650 was strikingly finished in pale beige metallic. For 1955 the model was up-dated with the swinging-arm frame and separate gearbox and continued in production until 1962. Harry's favourite machine for club runs, this un-restored Golden Flash has been sympathetically updated with Gold Star forks and front brake, electronic ignition and a Pearson clutch. Ridden to the Isle of Man and back in 2011, it didn't miss a beat. The machine is offered with Pearson parts list, Haynes workshop manual and ROI Vehicle Registration Certificate.
