The BSA Rocket Gold Star (RGS) was a 646 cc (39.4 cu in) air-cooled parallel twin motorcycle produced by Birmingham Small Arms Company (BSA) at Small Heath, Birmingham. Launched in February 1962, it was one of the final range of A10 twins, using a tuned A10 Super Rocket engine in the double-downtube Gold Star frame.
Rocket Gold Star production ended in 1963 due to the development of new unit construction successors, designated as A65 in the 650 cc capacity.
