Associated Motor Cycles
Associated Motor Cycles (AMC) was a British motorcycle manufacturer founded in 1938 by the Collier brothers, as a parent company for the Matchless and AJS motorcycle companies. It later absorbed Francis-Barnett, James, and Norton before incorporation into Norton-Villiers.
AJS had already been bought out by the Colliers in 1931. Sunbeam had been bought in 1937 from Imperial Chemical Industries. AMC designed an all new range of Sunbeam motorcycles, maintaining Sunbeam quality and engineering, but sold Sunbeam to BSA in 1943.
