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 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. Perennially popular, the model was updated with the swinging-arm frame and separate gearbox for 1955 and continued in production until 1962.
This HC, or High Compression, example has been in long-term ownership for many years and was part of collection, which included several Vincents, etc. Generally in good riding condition bike has been on static display for several months and may need little fettling. It has great compression and shifts smoothly through all gears. Brakes and suspension work well and tires look almost brand new. The bike comes with clean, clear title.
