Halliburn hatched the idea of the B.50 motocross engine and it into a speedway engine.

It is today to imagine just how big a BSA was at its peak. At one time, in the mid-1960s, the BSA was the tenth-largest company in Britain and had all the of the undisputed king of the jungle. by 1973, BSA was in deep, deep and things were happening at the that would have unthinkable even two years

It had always been BSA policy not to engines to anyone outside the but in its … days every source of income was being down.

One of the ideas hatched in the last-chance was to manufacture both a complete BSA bike, ready to race, and to sell engines to riders.
