1963 BSA Rocket Gold Star
Engine no. DA10R 7985
Widely recognized as one of the most desirable of all factory built café racers, the Rocket Gold Star arrived in February 1962 along with the first of BSA's new unit construction range to be known as A50 and A65. A combination of - mainly - Gold Star cycle parts and the A10 Super Rocket pre-unit twin-cylinder engine, the newcomer represented the last of the old 'pre-unit' line rather than a new departure and thus was destined for a relatively short life. For some reason best known to BSA the RGS frame was unique, although not that different from the production A7/A10/Gold Star item, as was the wider dual seat. The model was offered in a number of different forms and with a host of options relating to controls and equipment, for touring or racing. Mostly racing! Around 1,800 were made over an 18-month, but two-model-year, period.
"The motor was the Super Rocket type with light alloy cylinder head and sports camshaft but with compression ratio lifted to 9.9 to 1. Ignition was by magneto with manual control and the old dynamo was still used. The carburetor was a Monobloc...and the Siamese exhaust fitted as standard. In this form the engine developed 46hp at 6250rpm." There was one change in the lower right tube of the duplex loop Gold Star frame. "This ran straight under the engine, and did not have the kink in it demanded by the oil pump on the Goldie single cylinder engine."
This correctly restored example, found by and restored by expert Frank Diehl, formerly of Annapolis, Maryland, now of Myrtle Beach, South Carolina, was bought in 1989 from an Alan Corso of College Park Maryland as a basket case by the seller. It has been in a private museum since 1991. Before leaving for the sale it has been re-commissioned and is in excellent running order.
- According to the BSA records this is matching numbers machine was supplied to BSA Inc, New Jersey, on 20th August 1962.
