Introduced in 1962, the BSA A65 twin was the unit-construction follow-on to company's venerable A10 series. The powerplant retained the 360-degree crankshaft and single cam mounted at the rear of the cylinder block, but now engine internals and transmission were contained within a single set of cases. Marking it as a bold new step forward, the engine was treated to streamlined "power egg" styling. Soon the factory catalog would carry no fewer than 11 different models powered by the new-style engine, in both 500 and 650cc displacements. The first high-performance variant, the A65R Rocket, arrived in October of '63, aimed squarely at America's speed-obsessed throttle jockeys. It was superseded the following year by the yet-faster Lightning 650, first of the BSA unit twins to be equipped with the new splayed-port cylinder head fitted with dual carburetors.

This bike is in good shape and ready to have fun on the road.
