The BSA A65 Star was a Birmingham Small Arms Company (BSA) motorcycle aimed at the US market for unit construction twins. As well as giving a clean look to the engine, with the pushrod passages part of the cylinder block casting, unit construction reduced the number of places oil could leak from. A range of A65 Star twins was produced between 1962 and 1972.
