During the 1930s BSA concentrated on producing a range of dependable, well-made, competitively priced motorcycles.
The BSA single-cylinder range was redesigned by Val Page for 1937, the engines taking on many of the characteristics they would retain in the post-war era, most notably dry-sump lubrication, rear-mounted magneto and a distinctively shaped timing cover. There were two new overhead-valve offerings in the 500 class: the M22 Sports and M23 Empire Star. Their new engines were housed in a conventional chassis and drove via four-speed gearboxes, both of which benefited from the convenience of foot change.
This example of the Empire Star is equipped with a Smiths speedometer, ammeter, complete Lucas lighting set and Amal carburretor. The two-port head and the high level exhausts are special equipment not usually found on this model.
