BSA Blue Star
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 Empire Star was launched with the Blue Star remaining in the model range. In 1937 an entirely new engine designed by Val Page featured in the Empire Star and the Blue Star was dropped from the range. The Empire Star developed into the the famous Gold Star in 1938. The B33-3 OHV 249cc Blue Star was called the Blue Star Junior and the R33-5 348cc OHV Blue Star was known as the Sporting Blue Star. It was the W33-8 499cc OHV that became the most popular, however, and led to the development of the Gold Star.
