Triumph Trident 660

The Triumph Trident 660 is a naked motorcycle by manufacturer Triumph Motorcycles Ltd. Following a four year development programme, the Triumph Trident prototype was revealed at the London Design Museum on 25 August 2020. To disguise the final form, the prototype was painted all white with the exception of the engine.[2] A further, less-disguised and fully running prototype was released to the press a few weeks later, and shows the motorcycle undergoing final testing.[3]

Finally, the production version of the Trident was released to the press and journalists on 30 October 2020.[4]

The Trident is intended to compete in the middleweight sector, and be a rival to the likes of the Yamaha MT-07, Kawasaki Z650, Honda CB650R, and to a lesser extent the Suzuki SV650.[5]
