1950 BSA M21 600cc side valve single with a current V5C. The bike is complete and runs good. The engine revs well, good oil return, holds tickover well and does not smoke or rattle. It has been stood for some time, the rear stand is twisted, it needs some tidying, and a general recommission. Its basically a barn find… but one that definately does run good. I do not think it has ever been restored, it is more of a scruffy survivor. All original tinware, chronometric speedo and fittings throughout. 07718 593259. I can arrange delivery. Its priced fairly to sell… so the price is the price and those asking to buy it for less will not be owning it
