context_page_description: Sunbeam Cycles made by John Marston Limited of Wolverhampton was a British brand of bicycles and, from 1912 to 1956 motorcycles.
  On John Marston's death after the First World War it was bought by Nobel Industries, Nobel became ICI. Associated Motor Cycles bought it in 1937; then, BSA bought Sunbeam in 1943. Sunbeam Cycles is most famous for its S7 balloon-tyred shaft-drive motorcycle with an overhead valve in-line twin engine.
context_section_description: Many John Marston Sunbeam motorcycle models were produced. The first was a 350 cc in 1912 followed by a range of 500 cc singles and some v-twins. In 1924, a new model numbering system was introduced; Sunbeam Models 1 through 11. Other higher-numbered models were produced in later years. The majority had single-cylinder engines developing relatively low power, though winning the TT races often, the last time in 1929. A hallmark of all Marston Sunbeams was the superb quality and finish in black with gold-leaf pinstriping.
