The BSA Bantam was produced from 1948-1971 and is considered to be the most successful selling British motorcycle but it wasn't actually a BSA design. The design, gained as part of war reparations, was based off of a German DKW RT125. Over the years of production several different versions were made for road, trail and competiton use.
