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. Light, narrow and from certain angles looked just like a twin-port single, it was just what the conservatively minded motorcycling public wanted, and the Speed Twin would prove enormously successful. Performance was exemplary for a road-going 500, around 85mph being attainable by the Speed Twin while the Tiger 100 sports version was even faster. The latter's performance was boosted by the use of high-compression forged pistons and polished ports and internals, the result being a machine that could touch 100mph in road trim and exceed it with the silencer end-caps removed. When production resumed in 1946, the T100 reappeared with telescopic forks in place of the original girders, and separate dynamo and magneto instead of the pre-war version's magdyno. This sprung hub-equipped Tiger 100 was purchased by the vendor in April 2018. Apparently original, the Triumph is offered in 'oily rag' condition, ripe for sympathetic re-commissioning or possibly more extensive renovation. Sold strictly as viewed, the machine comes with the 2018 sales invoice; some expired MoTs; and a V5C document.
