Overview Motociclismo

According to the museum's fact sheet "BSA's 650 twin was a very popular touring machine, often seen with a sidecar attached. The polychromatic beige paint was a radical departure from the traditional black. With mild cam timing and relatively low 7 to 1 compression ratio, the Golden Flash gave outstanding flexibility, with a performance of 30 to nearly 100 m.p.h. in high gear."
