BSA Blue Star

The BSA Blue Star was a British motorcycle made by BSA at its factory in Small Heath, Birmingham, in production between 1932 and 1936. In 1936 a slightly uprated sports version, the Empire Star, was launched while the Blue Star stayed in the range as the New Blue Star, the Q21, and in 1937 an entirely new Val Page engine appeared in the Empire Star and the Blue Star was dropped. It became known for its reliability and handling. The 249 cc B33-3 was called the Blue Star Junior and the 348 cc R33-5 the Sporting Blue Star, while the 499 cc model, nicknamed the sea beezer, was the most popular, BSA's fifth best seller, and led to the development of the Gold Star.
