• First modern superbike

• Last design from Triumph Engineering

Frequently called the “first modern superbike,” the Trident was also the last new design from Britain’s Triumph Engineering Co. Ltd. It was inspired by the Triumph Speed Twin, a parallel twin designed in 1937 by Edward Turner. A sports version of the Speed Twin was introduced in 1938 as the Tiger 100. In effect, the Trident built on this with the addition of a third cylinder.

Introduced in 1968, the Trident had a companion BSA model, the Rocket 3. The two differed somewhat, however, in their engines and frames. The Trident is generally regarded as having a better riding position, a benefit of its Bonneville-derived frame. In 1971, the Trident was updated as the T-150V, with five-speed transmission and disc front brake, the model being sold here.

In very good condition, this Triumph T-150V Trident shows just 1,307 miles. Paint and brightwork both present well. The black leather seat is unworn, and the instruments are nicely detailed. Overall the bike is very clean and in excellent condition, with 4.10 H19 Dunlop Roadmaster tires, which are unworn and probably original. As first and last of the Triumph superbikes, this Trident has a special place in history.
