The BSA Rocket Gold Star was a BSA motorcycle included in the final range of A10 twins, using a tuned A10 Super Rocket engine in the double-downtube Gold Star frame.[1]

Development[edit]

Launched in February 1962, the total BSA Rocket Gold Star production was 1,584 bikes, of which 272 were off-road scramblers.[2] The later (1961-1963) 9:1 compression Super Rocket engine was used with a Spitfire camshaft and an Amal Monobloc carburettor gave 46 bhp (34 kW) as standard. Options such as Siamesed exhaust pipes and a close-ratio RRT2 gearbox could increase this to 50 bhp (37 kW) – and add 30% to the price.[3] Nine specials were made for export to California and one was fitted with a sidecar by Watsonian for the Earls Court Show in October 1962.[2]

Rocket Gold Star production ended in 1963 due to the development of new unit construction successors, designated as A65 in the 650 cc capacity.
