148 BSA Golden Flash Badge (1957)
The Golden Flash was introduced by BSA in 1950, Code-named the BSA A10, it was available in black and chrome; but it was the distinctive golden paint scheme that gave The Golden Flash its name. Its 649cc parellel twin engine was designed by Bert Hopwood who had worked at Ariel and |Triumph were he helped develope the 1937 Triumph Speed Twin which became the exemplar of the parallel twin engine layout for British motorcycles in the 1950s and 1960s. In April 1947 Hopwood joined Norton to design the Norton Dominator engine. in May 1948 BSA enticed Hopwood from Norton, and he was commissioned to create a competitive BSA parallel-twin. Launched in October 1949, Hopwood's A10 Golden Flash was increased to 650 cc (40 cu in), with a revised alloy rocker box and cast-iron cylinder head, plus an integral manifold for the single Amal carburettor. A semi-unit gearbox meant the primary chain was adjustable via a slipper tensioner within the primary chain case. The frame was available in rear rigid format, but the more common option was plunger suspension, adopted for the export market
