In 1965 an off road motocross BSA B44 named the ‘’Victor’’ was launched at the Earls Court Show. Developed from scramblers used by Jeff Smith to win the 1964 and 1965 500cc World Championships, the model proved so popular that Victor Grand Prix and Victor Enduro models were developed, as well as a road-going version, the 1967 Victor Roadster. The Victor Grand Prix Scrambler had a displacement of 441cc, and the Enduro model was known as the 441 Victor in the United States. BSA began offering a road version, the B44VR Victor Roadster, in 1967. When that model was exported to U.S. dealers in 1968, the name was changed to the B44SS Shooting Star. The B44VS Victor Special was also successfully exported to the US between 1968 and 1970.

In 1968 the B44 became BSA's top export model. The good availability of spare parts and the relative simplicity of the single-cylinder engine meant that the surviving examples are easily restored to as-new condition.
