Matchless was founded in 1899 by Henry Herbert Collier in Plumstead, London, and was one of the first companies to build motorcycles in Britain. The Collier family ran the firm for decades, and Matchless machines were raced successfully in the early years of the Isle of Man TT. In the 1930s Matchless became part of the Associated Motor Cycles group, which also included AJS and later Norton, creating one of the largest British motorcycle organizations.

Matchless is known for sturdy singles and twins that served civilian, police, and military riders. Models such as the G3 and G80 singles were widely used by the British armed forces during the Second World War and remained popular with civilian riders afterwards. The marque is remembered for solid construction, mechanical simplicity, and a long racing heritage. AMC production eventually moved through several factories in London and the Midlands before the group was absorbed into Norton Villiers in the 1960s.

Matchless workshop manuals cover single and twin engine overhaul, carburetion, magneto and electrical systems, clutch and gearbox, brakes, and wiring details. Factory specifications and maintenance procedures are essential for keeping these vintage motorcycles running correctly, and they reflect the engineering practices of their era.

These manuals are mainly of interest to classic British motorcycle enthusiasts, restorers, and workshops that service pre-1960s machines. Accurate documentation helps preserve Matchless motorcycles and supports correct, safe restoration work on these historic singles and twins. For owners today, the manuals provide the clearances, settings, and procedures needed to keep these old engines running sweetly.
