The BSA M20 was a British motorcycle made by Birmingham Small Arms Company (BSA) at their factory in Small Heath, Birmingham. Although initially viewed as a near failure by the War Office in 1936, the M20 evolved into one of the longest-serving motorcycles in the history of British military motorcycling, as well as becoming the most numerous type produced for World War II with 126,000[1] in active service. Many are still in use around the world today.[2] BSA M20](https://i.ytimg.com/vi/pkygQL6P69U/mqdefault.jpg)
