Overview[edit | edit source]
BSA Bluestar
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. 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 famous Gold Star in 1938
(also known as the M24).

It was the W33-8 499cc O.H.V. that became the most popular, however, and led to the development of the Gold Star.It was known as the "sea beezer" and it was BSAs fifth best seller.
