EDITOR TERLICK SAYS: It’s fair to say the two world wars were very good for the Birmingham Small Arms company. Created to build guns, BSA branched out into pushbikes and then motorcycles until, by the 1950s, it had grown to become the most successful motorcycle company — and one of the biggest companies of any kind — in the world. History tells us that, at its peak, BSA accounted for 25% of global motorcycle sales.The B31 was the first of BSA’s new models after WW2 and the first to boast telescopic front suspension. Its 350cc single-cylinder engine was good for 70mph and, while it was more of a daily rider than a performance bike, it was fast enough to keep buyers more than happy. This bike selling from Sydney looks like a great example of an important model in BSA’s history. Learn more here.
