Triumph Motorcycles has unveiled major 2026 updates for its popular middleweight Trident 660 roadster and Tiger Sport 660 adventure tourer, boosting power to 95hp and 68Nm via a revised 660cc triple engine. Both models gain triple throttle bodies, enhanced styling, adjustable suspension, and expanded electronics, aligning their performance with the Daytona 660 while improving throttle response and top-end pull.

Engine and Performance Enhancements
The 660cc inline-three now produces 95hp at 11,250rpm (up 14hp) and 68Nm at 8,250rpm, with peak outputs shifted higher (1,000rpm for power, 2,000rpm for torque) for stronger mid-to-high rev performance—80% torque from 3,000rpm. Key upgrades include individual 44mm throttle bodies per cylinder, larger front airbox, revised cylinder head with bigger exhaust valves, higher-lift cams, and a 20% redline increase to 12,650rpm. A bigger radiator and fan ensure better cooling across demanding rides.

Trident 660 Roadster Refinements
The Trident sharpens its roadster focus with sculpted bodywork: wider fuel tank with knee recesses, new seats, and an updated headlight akin to the Trident 800 for better comfort and presence. Chassis tweaks feature a Showa rear shock with preload/rebound adjustability alongside 41mm USD forks, twin 310mm front discs with Nissin calipers, and grippy Michelin Road 5 tires. Wet weight holds at 195kg with an accessible 810mm seat height.

Tiger Sport 660 Touring Upgrades
Tailored for adventure, the Tiger Sport gains an 18.6-litre fuel tank for extended range, revised radiator cowls, and adjustable windscreen for superior weather protection. Suspension offers 150mm travel front and rear via Showa USD forks and remote preload-adjustable monoshock, keeping wet weight at 211kg despite touring extras. Both share comprehensive tech: ride-by-wire modes (Sport/Road/Rain), six-axis IMU for cornering ABS/traction, cruise control, Triumph Shift Assist quickshifter, TFT-LCD dash with Bluetooth, and full LED lighting.

New 2026 color schemes add flair, with launches expected later this year in India to challenge segment rivals like Kawasaki Versys 650 and Honda CB650R. These evolutions promise refined versatility for urban, highway, and light adventure duties.
