BSA Pre-Unit Twins - The Complete Story
|INSIDE:||200 black & white photos 20 colour photos|
BSA was once the largest Ã and most successful Ã motorcycle company in the world. Many of the most famous Beezas were powered by twin-cylinder engines, in both vee and parallel configurations.
During the interwar years BSA built a series of side-valve and overhead valve v-twins in 500, 750 and 1000cc. After the Second World War, BSA built a family of vertical twins in 500cc [A7] and 650cc [A10] guises. Their names bring back fond memories: Star Twin, Shooting star, Golden Flash, Road Rocket, Super Rocket and the magnificent Rocket Gold Star.
This is the very first book to deal exclusively with both the interwarv-twins and the postwar A7/10 series.
