	The Norton Motorcycle Company (formerly Norton Motors, Ltd.) is an English motorcycle marque, originally from Birmingham, England, UK. It was founded in 1898 as a manufacturer of "fittings and parts for the two-wheel trade". By 1902 the company had begun manufacturing motorcycles with bought-in engines. In 1908 a Norton-built engine was added to the range. This began a long series of production of single and eventually twin-cylinder motorcycles, and a long history of racing involvement. During the Second World War Norton produced almost 100,000 of the military Model 16 H and Big 4 sidevalve motorcycles.
