History of BSA
The Story of a Motorcycle Legend
Since its founding in 1861, BSA has made a name for itself in military operations, sports, and manufacturing. The company had humble beginnings, but soon became one of the most well-respected names in history.
However, its story is a complicated one, and the company went through several iterations and a series of mergers before being dissolved in 1973. Nevertheless, it played a significant role in shaping the history of motorcycles in England.
Origin Story
Originally founded as Birmingham Small Arms in England during the 1800s, the company began producing rifles for the British military. They produced their first motorcycle in 1910—a 31/2 H.P. belt drive machine. The bike was a success and spawned many more models by the 1920s. In the ensuing years, BSA would buy several other motorcycle companies including Triumph, New Hudson, Ariel, and Sunbeam.
By the 1950s and 1960s, BSA was one of the largest mass-producers of motorcycles in the world. However, foreign competition from Japanese makers like Honda and Yamaha brought its fortunes down in the 70s and 80s, and it eventually went bankrupt in 1973.
Several companies have attempted to revive BSA since its discontinuation—but without success. Now, the Indian conglomerate
Mahindra & Mahindra, is set to give it another try with the 2021 launch of the BSA Gold Star, as part of its strategy to become a major global player in the motorcycle business.


History
The Early Years
The BSA motorcycle is one of the most iconic British motorcycles in history. The Birmingham Small Arms Company, or BSA, was started by gunsmiths in 1861. By 1880, they had become the largest arms manufacturer in Europe and were already producing motorcycles by 1910.
By the time the First World War broke out, BSA was already a well-established manufacturer of firearms and quickly pivoted to producing weapons for the British military.
After the war, BSA started producing motorcycles again and became a household name in Britain. BSA bikes quickly became a popular choice for both competition and street riding, due to their quality construction, dependability, and innovative design. Their early models were also very affordable—a huge draw for the average citizen.
The Post War Years
After World War II ended in 1945, BSA's wartime production of weapons was no longer necessary. The company decided to invest its resources into improving the existing models. They had been producing three-wheelers since World War I, but once the war had ended, that style of trike fell out of favor with consumers in favor of the more stable four-wheeled vehicles then available.
New dealerships opened in Britain and abroad as more people began riding motorcycles as a hobby rather than just a means of transportation. The company also expanded into new markets, designing and selling its first off-road bike in 1949. By 1960, it had introduced a wide range of models in different sizes and styles—and was the world's largest motorcycle manufacturer until 1972 when various factors led to its bankruptcy.
