Conclusion from the 1000PS editorial team
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.
