Although Triumph's 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. This example dates from 1953, by which time the Speed Twin had been upgraded with a stronger 8-stud cylinder barrel (replacing the original 6-stud) and Triumph's own telescopic front fork. This particular machine also has the Edward Turner-designed optional 'Sprung Hub', which endowed the rigid frame with a measure of rear suspension movement. Presented in 'barn find' condition, 'HBX 382' was acquired by the registered keeper in 1991 and has been off the road in dry storage for some considerable time. We are advised that the engine was last run some 12 months ago. Offered for restoration and sold strictly as viewed, the machine comes with a V5C document.
