Originally a famous bicycle maker, John Marston produced his first Sunbeam motorcycle in 1913. It was a side-valve single with and enclosed primary. Sunbeam quickly established a fine reputation for high-quality enamel finishes, enclosed chain drives and the sound engineering designs of J.E. Greenwood. Sunbeam motorcycles were made in England from 1913 to 1957.
