Matchless is one of the oldest marques of British motorcycles, manufactured in Plumstead, London, between 1899 and 1966. A wide range of models was produced under the Matchless name, ranging from small two-strokes to 750 cc four-stroke twins. In 1938, Matchless and AJS became part of Associated Motorcycles (AMC), both companies producing models under their own marques. During the amalgamations that occurred in the British motorcycle industry in the 1960s, the Matchless four-stroke twin was replaced with the Norton twin, ending a long history of independent production. By 1967, the Matchless singles had ceased production.
