Lot 613: c.1934 BSA 250cc Blue Star
The Depression of the early 1930s forced BSA to reduce its range of models, just ten being offered for 1932. Among these though, were two new overhead-valve sports models of 350 and 500cc, both typed ‘Blue Star’ and featuring tuned twin-port engines incorporating high-compression pistons, ‘hotter’ cams and stronger valve springs. A four-speed, foot-change gearbox was another feature common to what were then BSA’s top-of-the-range sports models. Both engines had vertical cylinders and magneto ignition, and were carried in conventional cycle parts with rigid frames and girder front forks. A 250cc Blue Star was added to the range for 1933. This apparently original 250cc Blue Star was acquired around 25 years ago and has not been touched since. Finished in BSA green with black cycle parts, it is offered for restoration and sold strictly as viewed. There are no documents with this machine.
