Eddie Dow, a motorcycle dealer from Banbury, near Oxford in the UK is credited with the Rocket Gold Star. He had built a reputation and a wealth of knowledge of BSA high performance singles and saw an opportunity to bridge the end of Gold Star production to the new unitary engine/gearbox models being released. He put the A10 Super Rocket twin-cylinder engine into mostly Gold Star cycle parts and produced one of the most desirable café racers of the day.
BSA raised the compression ratio of the Super Rocket engine to 9.25:1 and claimed a maximum power increase to 46bhp. Motor Cycle magazine tested a Rocket Gold Star in November 1962, summing up the new tested to 105mph BSA as a “scintillating high-performance road burner: good brakes, excellent rider comfort and docile traffic manners.” Produced for only two years, only 1,800 Rocket Gold Stars were ever made, and genuine examples are highly sought after today.
The motorcycle on offer here, hails from a discerning and meticulous collector and restorer, as can be plainly seen in the condition of the bike. A Rocket Gold Star “replica”, the machine’s build started with a genuine 1955 Gold Star Frame #CB32 2785 (certificate of authenticity photographed below), which houses a 1960 Super Rocket Engine Number DA10R7885, built by marque expert, Dean Collinson, to Rocket Gold Star Spec including cams, pistons, rings, bearings, bushings, valves, guides, etc. Fuel mixture is handled by New Amal 389 1-1/8” carb with all new fittings, petcocks and cloth braided hoses, while the gearbox was thoroughly “gone through” and refurbished as needed. For convenience and reliability, the bike was converted to Lucas 12v electronic ignition with solid state regulator and Alton 12v generator with a new battery.
Attention to cycle parts is equally as meticulous with 19” Akront flanged aluminum rims front and rear with new Avon Road Rider tires, while a beautiful restoration of the gauges make them look like jewelry. Cosmetically, the bike is exquisite with excellent paint, polished aluminum and chrome finishes. Stainless fasteners are used throughout.
The result is a wonderfully pleasing motorcycle to ride and own. The bike starts from cold consistently with one or two kicks (see video below) and is an utterly superb ride. It has strong power from a very taut engine, idles smoothly and is responsive on the throttle. It shifts smoothly through all gears with an equally smooth clutch action. The bike handles well and brakes as it should. The bike has covered over 1,000 miles since restoration to ensure proper run-in and subsequent re-torque of the engine and final sorting. All electrical systems work perfectly.
This sale represents a fantastic opportunity to acquire a wonderful classic with a nod to a seminal model in British motorcycling history, truly ready to ride anywhere and hold its own in any concours event.
