The BSA Blue Star is a British motorcycle made by BSA at their factory in Small Heath, Birmingham. The Blue Star range was produced between 1932 and 1936. In 1936 a slightly uprated sports version called the BSA Empire Star was launched with the Blue Star remaining in the model range and called the “New Blue Star, Q21”. The Blue Star became known for its reliability and handling. In 1937 an entirely new engine designed by Val Page featured in the Empire Star and the Blue Star was dropped from the range.

This late vintage BSA is an early Blue Star. Restored some time ago, its finish has 'mellowed down' somewhat, with use. A correct numbers machine, it will require some recommissioning before use and comes complete with a current V5C
