The front brake size is increased.

The 500 Gold Star is given a new cylinder head at the end of 1951 (designed by Bert Hopwood), and the 350 gets the same treatment part way through the next year. At the same time, BSA make plenty of detail changes to keep the bikes competitive on the track.

A new, duplex cradle, swinging arm frame is introduced, along with an improved gearbox, and the bikes' designations change to BSA BB34.
