BSA Model L

The BSA Model L was a British 349 cc four stroke motorcycle made at the company's Armoury Road factory in Small Heath, Birmingham, from 1923 or 1924. It was available with a side valve or an overhead valve engine, the overhead valve version being BSA's first, and shared a three speed hand change constant mesh gearbox, an Amac carburettor and chain final drive. It was one of the last flat tank models, with friction pad brakes acting on dummy rims built into the wheels and a hand adjustable mechanical oil pump with a sight glass. It scored well in the 1923 Scottish Six Days Trial and the International Trials in Sweden, and a side valve model cost 47 pounds 10 shillings new.
