The BSA Gold Star was a very popular sporting road machine, and was also one of the mainstays of Clubman's racing during the 1950s.
Post-war Gold Stars, in both 348cc B32 and 499cc B34 forms, featured new engines with alloy cylinder barrel and head, making it 20 pounds (9kg) lighter than the earlier cast iron B-series singles. They were available with different compression ratios, camshaft profiles, carburettors and exhaust systems, and two different cylinder heads, one for the Trials version and the other for all other models. They were then run on a dynamometer and the test results with power output were shipped with the bike.
Trials and scrambles derivatives proved the bikes versatility by chalking up an impressive record in off-road competition. In the early post-war years BSA's top trials rider was Irishman Bill Nicholson who, together with rider/engineer Brian Martin, developed the B32/34 Gold Star into formidable trials machines.
Built from a touring spec bike in around 1980, as an International Six Day Trial replica, UYJ was very well put together by our vendor, who subsequently used it on many vintage trials events during the eighties, and won several medals with it. The bike started very well on test with a smooth engine, and rides nicely around our premises.
