The Birmingham Small Arms Company was much older than the motorcycle, but motorcycle production began in the early twentieth century. BSA’s scale made it a dominant British manufacturer, spanning utility Bantams, sporting Gold Stars and parallel twins. The historic brand later returned with a modern Gold Star.
