Description
Although BSA were latecomers to the motorcycle market, they did not make their first complete machine until 1910, they soon became a market leader. Vast numbers of good reliable motorcycles left their Birmingham factory in ever-increasing numbers and with such an extensive range of models there was something to meet almost every requirement. Their familiar slogan The most popular motorcycle in the world was widely recognised, so much so that letters from overseas bearing only this slogan were invariably delivered to Armoury Road in Small Heath. The company began making vee twins in 1920, but it was not until the early post-World War 2 period that vertical twins became a key feature of their model range. If everything had gone according to plan, they expected to launch two such models at the 1940 Motor Cycle Show. Well aware of the potential of Edward Turners Speed Twin Triumph which broke new ground in 1937, they lost little time in producing prototype designs that would match the Triumph, and had them running in 1939. Sadly, World War 2 curtailed further development and when the production of civilian models resumed after the war, two entirely new models had taken their place. The first was a 495cc vertical twin designed by Herbert Perkins, the A7 model. It was subsequently redesigned in 1949, after Bert Hopwood had joined BSA as Forward Product Designer. Hopwood also took the opportunity to introduce a 646cc variant in 1950, the renowned A10 Golden Flash model, which became BSA.
