Triumph Trident 660 2025

Triumph Trident 660 2025

The Triumph Trident 660 remains the clever naked bike in the mid-range in 2025. Successful electronics upgrade, increased comfort, suitability for everyday use confirmed. Only the dynamics and suspension leave a little to be desired for riders with sporting ambitions. Anyone looking for a well-balanced, technically well-equipped naked bike will find a strong partner in the Trident 660.

Balanced handling

high-quality electronics & quickshifter as standard

effective cruise control

well-modulated brakes

attractive three-cylinder sound

solid suitability for everyday use

low weight

safety-relevant Advanced Rider Assistance Systems as standard, great engine

Traction control is too conservative even in Sport mode

quickshifter reacts sensitively to imprecise shifting impulses

hook spanner required for suspension adjustment

Triumph Street Triple 765 RS 2017

Triumph Street Triple 765 RS 2017

The top model among the Street Triples fully deserves the designation. Sportier in all respects than the R version, the RS presents itself on the country road as a fun machine that has few opponents to fear. Trackdays on the racetrack are also an issue, especially since the engine is very sharp, the Brembo brakes are super-sporty and the suspension with the Öhlins damper is wonderfully precise. The handling is a stunner anyway, the Street Triple is still the lightest in its class. The standard quickshifter further consolidates the position of the top model.
