1957 BSA 500CC Gold Star Dirt Tracker

The BSA Gold Star has a 500cc OHV 4-stroke single engine and weighs in at only 325 pounds, giving it excellent handling and a great racing bike – especially on half mile and occasionally one mile tracks. Throughout the 1950′s and 1960′s, BSA was Harley Davidson’s main opponent on the track in American Grand National Championship Racing.
