The original BSA Gold Star.

The new Gold Star was based around BSA's OHV B-range of singles. The first version was the bench-tested, all-alloy 348cc engined B32, which used the marque's plunger frame and which boasted a wide range of options - you could specify cams, compression ratio, carb, cylinder head, exhaust, gearbox ratios, lighting, tires, electrical systems - you name it. The components were carefully selected from stock, and the bikes skilfully assembled by hand. The alloy head and barrel meant that the Gold Star was some 20lb lighter than its all-iron stablemates. As a Clubman's racer, the Gold Star proved to be fabulously successful, and it dominated the 350 class from 1949 to 1956.
