Giving birth to the engine’s design, this 1938 Triumph Speed Twin showcases Edward Turner’s vertical twin motor. With a 498cc, twin overhead valve construction, the Speed Twin made a solid 27hp and was the first truly successful British twin to come to market.
Early models were only available in ‘Amaranth red’, and were hand painted with gold pinstripes. The hard-tail and initial girder forks meant that the only real suspension for the rider was the sprung seat. Passengers would have to survive with only a doubly thick pad over the rear fender. Ouch.
