Overview[edit | edit source]

BSA B26






When BSA's single-cylinder range was redesigned by Val Page for 1937, the engines took on many of the characteristics they would retain in the post-war era, most notably dry-sump lubrication, rear-mounted magneto and that distinctively shaped timing cover. There were four new offerings in the 350 class: the sidevalve B23 and a trio of overhead-valve models.

These comprised the B24 Empire Star, the B26 Star and the B25 Competition model, the latter equipped for trials use. The B-series quartet lasted until the wholesale revision of the range for 1940, which saw all four dropped.
