BSA Model K

The BSA Model K three-speed motorcycle with vertical single-cylinder side-valve engine was one of BSA’s main pre-World War I models, popular with solo and sidecar riders across Britain and the markets British colonials. Civilian supply of motorcycles to the BSA ceased in 1916 due to the British government’s wartime demands for military production, with the BSA concentrating for a period largely on the manufacture of small arms. Production of Model K motorcycles resumed after the war and continued into the 1920s.
