The Douglas Dragonfly is a motorcycle designed and built by Douglas motorcycles in Bristol. The last motorcycle produced by the company, the 1955 Dragonfly was an all-new motorcycle built to use an improved version of an existing engine. Despite its riding comfort, which was "equal to a car's", it did not sell well, and only 1,457 Dragonfly motorcycles were produced before the company was taken over and production ended in 1957.[1][2] Very few Douglas motorcycles survive today.
