Rocket engine
Gold Star tuner and dealer, Eddie Dow, had a customer that wanted to be supplied with a Gold Star fitted with a Super Rocket engine. BSA supplied a Gold Star less engine and a separate Super Rocket engine. Dow assembled the special. The special was well received and the BSA management decided to put the concept into limited production. BSA had previously produced a bike with an A10 engine in a Gold Star frame - the 1957 Spitfire Scrambler. It has been suggested that as both the Gold Star and the A10 were at the end of their production life, and BSA wanted riders to switch to the new unit twins, this was a convenient way to use up the stock of pre-unit parts.
