Although Edward Turner's Triumph Speed Twin caused a sensation when it appeared at the 1937 Motorcycle Show, few of its admirers can have guessed how influential the design would prove to be. True, there had been vertical twins before; indeed, Turner's predecessor at Triumph - Val Page - had designed one a few years previously, but the Coventry firm's newcomer established a formula that would be adopted by all of Britain's major motorcycle manufacturers in the succeeding decade. And whereas previous vertical twins had suffered from excess bulk, Turner's was lighter and narrower across the crankcase than the contemporary single-cylinder Tiger 90, and from certain angles looked just like a twin-port single. Performance proved exemplary for a road-going 500, better than 100mph being attainable under favourable conditions.
This particular Speed Twin was completely restored in 2012 when works undertaken included shot-blasting and powder-coating the frame, the colour used being matched to the original Amaranth Red. In addition, the engine was completely rebuilt and the gearbox, magdyno and front forks refurbished. Parts renewed included the clutch, control cables, electrics, wheel rims, tyres and tubes. Most of the work was done professionally. Described as in generally excellent condition, the machine is offered with dating letters, current road fund licence, V5C registration document and recently expired MoT (January 2014).
