Old 1925 Douglas Model CW 350cc Two Cylinder Motorcycle Start Up
via
The Bristol-based Douglas Foundry took up motorcycle production in 1907 with a machine powered by a horizontally-opposed twin, and the company would keep faith with this engine layout until it ceased motorcycle production in 1957. Fore-and-aft installation made for a slim machine with a low centre of gravity, and the design’s virtues were soon demonstrated in competition. source/image(PrtSc):
