Mileage 6680 Engine 591cc Rego TBA Just arrived - This 1951 BSA M21 is a real piece of history. Made from 1937 to 1961, the M20/M21 were one of the longest serving motorbikes in the British military as well as the most produced for World War II, with 126,000 in active service. The air-cooled 591cc four stoke single cylinder side valve were simple with low compression and plenty of low-end torque. They ran a BSA four speed manual transmission, telefork front suspension, and drum brakes all round. Reliable and affordable, they were also designed with sidecar additions in mind, with easy access to premade mounting points. The current owner has had the bike for 5 years, and it is back on the market only due the owner's surplus of bikes. This M21 is a great example, comes with a carby kit, and would make a nice project for someone looking to get it back up and running. Contact Ben Finnis - 0411 744 190.
