The Williamson Flat Twin was the a British motorcycle made in Coventry by Willaim ('Billy') Williamson, who had been MD of the Coventry-based Rex company. He teamed up with William Douglas (of Douglas Motorcycles to develop new prototype motorcycles under the name Williamson-Douglas and employed Billy's brother Howard as a test rider. Douglas had been developing a 964cm³ water-cooled flat twin engine that could be used either for light cars or motorcycles. Billy Williamson fitted this engine into a frame with Douglas-Druid girder forks and a Douglas two-speed gearbox and a foot-operated clutch which was launched in 1912 at a cost of £82. In 1913 an air-cooled version was added to the range and in 1914 a kick starter was added. Production was halted by the first world war and in 1919 the only engines availabe were JAP 980 cm³ air-cooled side valves, so Williamson redesigned the frame to fit. Unfortunately Billy Williamson suffered a fatal heart attack in 1920 after only twenty motorcycles had been produced.
