Triumph has rolled out its most substantial update yet for the 660cc middleweight range, introducing a significantly uprated engine along with chassis, styling and feature enhancements for both the Triumph Trident 660 and the Triumph Tiger Sport 660.
1. Triumph Trident 660 and Tiger Sport 660 now produce 95hp and 68Nm
2. Both models now move to a triple throttle body setup
3. Peak power is produced 1,000rpm higher and peak torque 2,000rpm higher
Triumph 660 duo updated: What’s new?
Both motorcycles now produce the same output as the Daytona 660
At the heart of the update is a heavily revised 660cc inline three-cylinder engine. Both motorcycles now make a claimed 95hp at 11,250rpm, up by 14hp, while peak torque increases to 68Nm at 8,250rpm. This tune is inline with what we have experienced on the Daytona 660, however the torque figure is 1Nm down here. As opposed to the earlier tune of the Trident, it now produces peak power higher up in the rev-band (1,000rpm higher) that should aid it’s top-end performance – a point in the rev band where it would earlier run out of breath. The torque too is delivered higher in the rev band (2,000rpm higher) but Triumph also claims that 80 percent of this torque is available from 3,000rpm.
A key technical change is the move from a single throttle body to three individual 44mm throttle bodies, one per cylinder. According to Triumph, this improves throttle response and contributes to stronger mid-range and top-end performance. Supporting updates include a larger front-mounted airbox, revised cylinder head with larger exhaust valves, a higher-lift cam profile, and a 20 percent higher redline at 12,650rpm. The cooling system has also been upgraded with a larger, repositioned radiator and fan.
Trident 660
For 2026, the Trident 660 leans further into its roadster identity. Triumph has introduced new bodywork, including a wider, more sculpted fuel tank with deeper knee recesses, revised seats, and an updated headlight, likely to be the same as the bigger Trident 800. The brand says these changes improve both rider comfort and visual presence.
Chassis updates include a new Showa rear shock with preload and rebound adjustment, paired with the existing Showa 41mm USD front forks. Braking hardware remains unchanged, with twin 310mm front discs and Nissin calipers, while Michelin Road 5 tyres continue as standard. Triumph claims a wet weight of 195kg, along with a low 810mm seat height aimed at keeping the bike approachable for a wide range of riders.
The electronics package remains comprehensive, with ride-by-wire enabling Sport, Road and Rain modes, a six-axis IMU for cornering ABS and traction control, cruise control as standard, and Triumph Shift Assist for clutchless gear changes. A TFT-LCD instrument cluster with Bluetooth connectivity is also fitted as standard.
Tiger Sport 660
The Tiger Sport 660 receives the same engine upgrades but applies them to a more touring-oriented brief. One of the most notable changes is the larger 18.6-litre fuel tank, which Triumph says improves range on longer rides. Revised bodywork, including new radiator cowls, is claimed to enhance weather protection, while the adjustable windscreen offers a wider range of coverage.
Suspension travel remains longer than on the Trident, with Showa USD forks and a rear monoshock providing 150mm at both ends. The rear shock also features remote preload adjustment, making it easier to adapt the bike for pillion use or luggage. Despite the added touring hardware, Triumph claims a wet weight of 211kg.
As with the Trident, the Tiger Sport comes equipped with ride modes, IMU-based cornering ABS and traction control, cruise control, quick shifter and full LED lighting as standard.
Both models also receive new colour options for 2026. Whether the claimed gains in performance, refinement and versatility translate into meaningful on-road improvements will be clearer once they come to our shores. We expect Triumph to launch the updated Trident and Tiger Sport 660 later this year.
