BSA B44

The BSA B44 was a series of 441cc single-cylinder motorcycles produced by Birmingham Small Arms Company (BSA) from 1966 to 1970. The B44 designation covered several models, including the B44 Shooting Star (road bike), the B44 Victor Special (road/scrambler), and the B44 Victor Grand Prix (motocross).

The engine was a development of the earlier B40 350cc unit, enlarged to 441cc to provide more power and torque. The B44 engine was known for its relatively light weight and strong performance for its size, making it competitive in scrambles (motocross) and trials events. The Victor models were particularly popular in the American market, where their light weight and agile handling were well-suited to off-road riding.

The BSA B44 models represented a significant evolution in BSA's single-cylinder motorcycle design. Despite their relatively short production run, they are considered classic examples of British motorcycles and remain popular among enthusiasts today. The engine design also influenced later BSA models.
