B.S.A. A10 SUPER ROCKET. 650 TWIN (1957-63) No 2
The BSA Super Rocket is a British motorcycle that was a development of the BSA Road Rocket that evolved from the Golden Flash. The A10 had a reputation for reliability but was struggling to compete against the Triumph engines and the Norton Featherbed frames, so the Super Rocket offered more performance and better handling than earlier models
Launched in 1957 the BSA Super Rocket had a new alloy head and an Amal TT 'racing' carburettor. 1961 saw a new "357" full-race camshaft with high lift, more dwell and faster valve action to improve performance
A 'clubman' version, the BSA Rocket Gold Star was produced with rearsets, 'clip-on' handlebars and a tuned engine but this was something of a 'special' and was produced at the same time as the Super Rocket. Over the years the A10 built a reputation as a rugged and reliable bike, ideal for sidecar use (which was popular when cars were too expensive for many people to run).
It was only with the emergence of the unit construction BSA's that the A10 finally ended its decade of success.
