BSA 1924 249 cc side valve single Lightweight Model B “Roundtank” frame # B 1570 engine # B 1711
In January 1924 BSA stunned the motorcycle market by introducing a motorcycle that cost less than forty pounds, an absolute bottom price. The machine was designed in such a way that it could be mass produced. With a top speed of 45 mph, a weight of 170 lb and an average fuel consumption of 120 mpg this little machine became a giant success for the company.
In the first 12 months of its existence some 15,000 machines were sold and in its entire production run of about five years some 35,000 Lightweights found satisfied customers.
It wasn’t a “roundtank” any more by then though, since the petrol tank had become a more conventional rectangular device.
The little machine had 24 inch wheels, a two-speed gearbox and a mechanical oil pump.
This charming and practical vintage machine is an older restoration and comes complete with acetylene lighting system.
