BK Auto Auctions presents this classic 1953 BSA M20/SideCar finished in an awesome Black with pin stripes with a black leather interior. Power comes from a single-cylinder side valve four stroke engine displacing 496 cubic inches, transferred to the rear wheel through a four-speed transmission with chain drive. This head turning BSA has the Style to get you where you’re going. This BSA is being sold on a Bill of Sale.


The heavy-framed cycle was designed by Val Page and was created with the use of a sidecar in mind.  While many came with a sidecar, there were also two-wheeled models.  Power came from a single-cylinder side valve four-stroke engine displacing 496 cubic inches, transferred to the rear wheel through a four-speed transmission with chain drive.  While relatively low compression, the powerplant delivered lots of low-end torque.  The popularity of the military models prompted BSA to begin production of a civilian version, also often equipped with a sidecar, after the end of WWII

For over 50 years, the Birmingham Small Arms Company, LTD was a major British industrial combine with manufacturing interests spanning a wide range of products for both civilians and the British military.  With a history of bicycle production predating the company’s founding in 1919, it was logical that motorcycle manufacturing would be an area of expansion for the conglomerate to explore.

BSA, as the combine was generally referred to, and affiliated marques Triumph and Norton, were major players in the motorcycle industry until the early 1970’s when the company failed to address the rising popularity of Japanese and European brands among consumers in both England and North America.  The final BSA motorcycle came out in the 1972 model year, with Norton and Triumph continuing thanks to a government-sponsored reorganization plan.

This 1953 BSA with accompanying sidecar has been a part of the present owner’s portfolio since September 2009 and has been part of a static display during his ownership and stored in a humidity-controlled environment.  While no attempt has been made to start this motorcycle, the engine appears to turn over freely.
