TT100 (motorcycle tyre)

[5] Originally introduced in early 1968 as the Roadmaster K81 rear tyre[6] by Dunlop Rubber Co. Ltd,[7] the tyre was renamed "TT100" because it was the first production tyre to reach a lap speed of 100 mph over the Isle of Man TT race course when Malcolm Uphill rode his works Thruxton Bonneville to victory in 1969 with a fastest lap of 100.37 mph during the 750 cc class production race.

[8][9][10] The feat was repeated in 1971 when Ray Pickrell averaged 100.01 mph on a Triumph Trident Slippery Sam replica, a modified version of the motorcycle the tyre was designed for.

[11] The tyres were standard fitment on production models of BSA and Triumph triple motorcycles.

[1] The tyres featured a unique "Trigonic", or triangular, profile which provided ample outstanding grip for the day,[14] and an identical tread pattern to front and rear instead of the usual circumferentially ribbed front tyre of the day.

[3] Considered a "super tyre",[15] it continues to be made utilising the latest technologies and materials for improved performance.
