New Delhi: Triumph has updated its 660cc motorcycles, the Trident 660 and the Tiger Sport 660, with major mechanical and design changes. Both bikes now get a stronger engine along with updates to the chassis, styling, and features.
Both motorcycles are equipped with different riding modes according to the riders’ needs. Both of the bikes will be offered in new colour options for 2026. Triumph is expected to launch the updated Trident 660 and Tiger Sport 660 later this year.

What has changed in the Triumph 660 bikes?
Tiger Sport 660 and Trident 660
Both motorcycles now use the same engine tune as the Daytona 660. The 660cc inline three-cylinder engine produces 95 hp at 11,250 rpm, which is 14 hp more than before. Torque has also increased to 68 Nm at 8,250 rpm, although it is slightly lower than the Daytona’s figure.
Compared to the older Trident tune, peak power now comes 1,000 rpm higher, helping improve top-end performance. Torque is delivered 2,000 rpm higher, but Triumph says 80 per cent of the torque is available from 3,000 rpm, which should keep the bikes usable at low speeds.

Upgraded Performance. Adventure Extended. Whether carving city streets or touring for the weekend, it’s the perfect blend of versatility and fun.

One of the main changes is the switch from a single throttle body to three separate 44 mm throttle bodies, one for each cylinder. Triumph says this improves throttle response and performance in the mid and top rev ranges. Other updates include a larger airbox, a revised cylinder head with bigger exhaust valves, a higher-lift camshaft, and a redline increased by 20 per cent to 12,650 rpm. The cooling system has also been upgraded with a larger radiator and fan placed in a new position.

For 2026, the Trident 660 has been updated to feel more like a proper roadster. It gets new body panels, a wider fuel tank with deeper knee cut-outs, revised seats, and a refreshed headlight design, which is expected to be similar to the one on the Trident 800. Triumph says these changes improve comfort and overall appearance.
The chassis now gets a new Showa rear shock with preload and rebound adjustment, while the 41 mm Showa USD front forks remain unchanged. Brakes stay the same with twin 310 mm front discs and Nissin calipers, and the bike continues to use Michelin Road 5 tyres. The claimed wet weight is 195 kg, and the seat height remains low at 810 mm.
Electronics include ride-by-wire with Sport, Road and Rain modes, a six-axis IMU for cornering ABS and traction control, cruise control, and a quick shifter. A TFT-LCD display with Bluetooth connectivity is standard.

The Tiger Sport 660 gets the same engine upgrades but is focused more on touring. A larger 18.6-litre fuel tank has been added to improve riding range. The bike also receives revised bodywork and new radiator cowls for better wind protection, along with an adjustable windscreen.
Suspension travel remains longer than the Trident, with 150mm at both ends. The rear shock comes with remote preload adjustment, which is useful when riding with a pillion or luggage. Despite these additions, Triumph claims a wet weight of 211kg.
Like the Trident, the Tiger Sport 660 comes with ride modes, IMU-based cornering ABS and traction control, cruise control, a quick shifter and full LED lighting as standard.
