Triumph Trident 660 and Tiger Sport 660 Update Brings Major Mechanical Gains

The Triumph Trident 660 and Tiger Sport 660 update marks the most extensive revision yet for the brand’s 660cc middleweight lineup. The latest changes span engine performance, chassis refinement, design tweaks, and feature upgrades, aligning both motorcycles more closely with Triumph’s newer performance benchmarks.
Triumph Trident 660 and Tiger Sport 660 Update: Engine and Performance Changes
Both models now match the output of the Daytona 660, powered by a comprehensively reworked 660cc inline three-cylinder engine. Maximum power rises to 95hp at 11,250rpm, while peak torque increases to 68Nm at 8,250rpm, representing a significant step up over the earlier tune.

• Peak power arrives 1,000rpm higher

• Peak torque shifts 2,000rpm higher in the rev range

• 80 percent of torque is available from 3,000rpm

This revised tuning improves top-end performance while retaining strong low- and mid-range usability.
A major technical highlight of the Triumph Trident 660 and Tiger Sport 660 update is the switch to three individual 44mm throttle bodies, replacing the earlier single-body setup. This change is aimed at sharper throttle response and improved airflow across the rev range.
Supporting updates include a larger front-mounted airbox, a revised cylinder head with bigger exhaust valves, a higher-lift cam profile, and a redline raised by 20 percent to 12,650rpm. Cooling efficiency is improved through a larger radiator and repositioned fan.
Triumph Trident 660: Design, Chassis, and Features
For 2026, the Trident 660 reinforces its roadster character with updated bodywork. Changes include a wider, more sculpted fuel tank with deeper knee cut-outs, revised seats, and an updated headlight design. According to Triumph Motorcycles, these revisions enhance rider comfort and visual presence.
Chassis hardware sees a notable upgrade with a new Showa rear shock offering preload and rebound adjustment, working alongside the existing 41mm Showa USD front forks. Braking components remain unchanged, with twin 310mm front discs and Nissin calipers, while Michelin Road 5 tyres continue as standard.
Key specifications include:

• Claimed wet weight of 195kg

• Seat height of 810mm

The electronics suite remains extensive, featuring ride-by-wire with Sport, Road, and Rain modes, a six-axis IMU enabling cornering ABS and traction control, cruise control as standard, and Triumph Shift Assist for clutchless upshifts and downshifts. A TFT-LCD instrument cluster with Bluetooth connectivity is also standard.
Tiger Sport 660: Touring-Focused Enhancements
The Tiger Sport 660 adopts the same mechanical upgrades but applies them to a more touring-oriented package. One of the most significant changes is the larger 18.6-litre fuel tank, intended to extend riding range on longer journeys.
Revised bodywork, including new radiator cowls, improves weather protection, while the adjustable windscreen offers a broader range of coverage. Suspension travel remains at 150mm front and rear, delivered via Showa USD forks and a rear monoshock.
The rear shock features remote preload adjustment, allowing easier setup changes when riding with a pillion or luggage. Despite the added touring equipment, Triumph claims a wet weight of 211kg.
Standard equipment mirrors the Trident 660 and includes ride modes, IMU-based cornering ABS and traction control, cruise control, a quick shifter, and full LED lighting.
Both motorcycles receive new colour options for 2026. The real-world impact of the Triumph Trident 660 and Tiger Sport 660 update in terms of performance, refinement, and versatility will become clearer once the models reach the market, with launches expected later this year.
