AJS is one of the best-known names in British motorcycle history. Founded in 1910 by the Stevens brothers, in Wolverhampton, the company produced well-built touring and sporting machines for the next twenty years. In 1931 the financial problems that had dogged the company came to a head and AJS was wound up. Its saviour was Matchless, who moved production to Plumstead, London, but retained the AJS name as an important part of the scene. Over the years the AJS and Matchless ranges had more and more in common, and by the post-war period the bikes were virtually identical, but the AJS name graced some of the best-loved bikes including the stunning 7R racer. The complete story of the AJS and its motorcycles is told here from the early days in the Midlands to the end, as part of the AMC combine.
