Elstar were motorcycles produced in Birmingham from 1965 to 1971.
The name came from the combination of the founder, Alf Ellis and the BSA Star model, as his early grass-track frames were built to take that engine. There was also a speedway version with a JAP engine, and this was followed by trials models in kit form. Construction was simple and the engine cradle could be varied to suit. British or foreign engines were used together with a variety of wheels and forks.
The firm came to an abrupt end when Alf Ellis was killed in a car crash.
