2025 Triumph Trident 660 – First Look
Six-axis IMU, cruise control and upgraded forks for modern-retro roadster
Triumph had a hit on its hands when it launched the Trident 660 for the 2021 model year, claiming sales of more than 35,600 units worldwide. That made it an easy call to update the roadster for 2025, giving it upgraded suspension and electronics.
The engine remains a 660cc liquid-cooled DOHC Inline-Triple, claiming the same 80 hp at 10,250 rpm and 47 lb-ft. at 6,250 rpm as the previous model. While the peak figures are unchanged, Triumph gave the Trident a new Sport ride mode, offering a more responsive mode to the returning Road and Rain modes.
For 2025, Triumph gave the Trident a six-axis IMU, unlocking cornering ABS and cornering traction control. A bidirectional quickshifter is now offered as standard equipment (it was previously an accessory), as is cruise control.
Up front, the 2025 Trident 660 uses a Showa 41mm Separate Function Fork Big Piston (SFF-BP), replacing the previous SFF unit. The top yoke is also new, now a forged aluminum piece. The preload-adjustable Showa RSU rear shock is unchanged.
The Nissin-supplied braking system consists of dual two-piston calipers up front with 310mm discs, and a single-piston caliper with a 255mm disc at the back. That’s all unchanged from 2024, though the updated model does receive a new forged aluminum brake pedal.
The Trident’s retro-modern styling returns with four color schemes: Cosmic Yellow, Cobalt Blue, Diablo Red, and Jet Black.
The 2025 Triumph Trident 660 will arrive in U.S. dealerships in December, with pricing starting at $8,595.

Lets see a comparo of the Trident, a Suzuki GSX-8, a Yamaha MT-07, and more at this price point.
My 2023 Triumph Trident wet weight was 417 pounds and my fuel capacity was 3.7 gallons. What increased the weight for 2025 and why is the tank capacity down for 2025?
