The B26 Star was one of the 350 cc overhead-valve singles in the 1937 range redesigned by Val Page. It introduced features that stayed with BSA singles after the war, such as dry-sump lubrication, a rear-mounted magneto and a distinctive timing cover. The B-series 350s were dropped in the 1940 revision.
