The BSA A65 Star was a Birmingham Small Arms Company (BSA) motorcycle aimed at the US Large side panels were fitted to cover the space behind the engine but they contributed to a dated look. This was reinforced by engine vibration.

If you wanted handling in the s, you bought a Norton and if you wanted a high-performance engine, you went for a Triumph. In many ways the BSA A7 and A10 and cc twins were the definitive British twins of the period but, apart from the Rocket Gold Star, still failed to lure the performance-oriented enthusiast. The other problem afflicting the A7 and A10 was they were perceived as old-fashioned as they retained a separate engine and gearbox.

In response to the increased demand for unit-construction twins, BSA released the cc A50 and cc A65 in Retaining many components from the earlier A10, including a bulletproof bottom end, the A65 had considerably more oversquare engine dimensions of 75 x 74mm and an improved cylinder head design. This better-breathing cylinder head eventually allowed some versions to produce up to 55 horsepower. The unit-construction engine had clean lines and the overhead valves were still operated by pushrods and a single camshaft located behind the cylinders.

With the intention of adapting the engine to US short-track dirt racing, the primary drive was by a stronger Triplex chain. The new engine looked bulkier than its predecessor but was actually 14kg lighter and 40mm shorter.
