Pros and Cons in comparison

Triumph Street Triple 765 RS 2019

As before, the RS top model is indeed the most desirable of the Street Triples. In addition to the usual playful handling, the super-direct Brembo brakes and the lively character of the three-cylinder engine, there is now a more bulbous mid-range, upgraded electronics as well as a Brembo M50 brake and the once again sharpened appearance. Thanks to the very sporty Pirelli Supercorsa SP V3 tyres, trackdays are indeed a serious issue, and the now standard shift assistant with blipper function greatly increases the incentive to switch to the new model. A wonderful fun machine for both country road and track!

Fantastically lively engine

high quality standard

quickshifter with blipper as standard

roaring sound

excellent Brembo M50 brake system

ABS and traction control as standard

Triumph Trident 660 2026

The Triumph Trident 660 takes a big step forward for the 2026 model year and now fully utilises the maximum throttleable power of 95 Horsepower in the A2 class. The clever mid-range naked bike also continues to score points with a complete electronic equipment package ex works and a 6-axle IMU. Anyone looking for a well-balanced, technically well-equipped all-round roadster will find a strong partner in the Trident 660.
