Overview[edit | edit source]

BSA DB34 Gold Star 500





The BSA Gold Star is a motorcycle made by BSA from 1938 to 1963. They were 350 cc and 500 cc single-cylinder four-stroke production motorcycles known for being among the fastest bikes of the 1950s. Being hand built and with many optional performance modifications available, each motorcycle came from the factory with documented dynamometer test results, allowing the new owner to see the horsepower produced.


When café racing culture was at its height in the late Fifties and early Sixties, BSA’sGold Star was king. The Goldie’s 500cc single-cylinder engine had more than enough performance to top the magic ‘ton’ and the bike’s striking beauty made it stand out from the much more common parallel twins of the era.

Tales of slipping Goldie clutches up to 30mph in first and snicking into top while accelerating at 95mph created a mystique around BSA’s road-legal racer, so it was already a legend by the time the last one was made in 1963.The legend remains strong today.

Away from town a good BSA Gold Star is everything the legend suggests. Fast, exhilarating and rewarding. Good ones start from around £7000, but think of them as an investment. Buy right and you won’t lose money on a Goldie; if anything you’ll make money. Not that, once you’ve bought and ridden one, you’ll ever want to sell.
