BSA pre-unit motorbikes are popular machines, including the Gold Flash and Gold Star, Road Rocket and Star Twin as well as the versatile singles and lightweights. With their engine and gearbox separate they are simple to work on and lovely British bikes to ride. Spares for models like the B31 and B33 as well as the M20 (a reliable motorcycle used by the military) are readily available and we make a number of hard-to-find items in house. These classic bikes show no sign of becoming obsolete.
