The BSA Blue Star is a British motorcycle made by BSA at their factory in Small Heath, Birmingham.
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”.
In 1937 an entirely new engine designed by Val Page featured in the Empire Star and the Blue Star was dropped from the range.
that became the most popular, however, and led to the development of the Gold Star.
