The 2026 Triumph Trident 660 receives its most significant update yet, headlined by a higher-performance 660cc triple engine producing 95hp at 11,250rpm and 68Nm of torque at 8,250rpm. The engine upgrades include three individual 44mm throttle bodies (replacing the single throttle body), a larger front-mounted airbox, revised cylinder head with larger exhaust valves, and a higher-lift cam profile. The redline has been raised by 20 percent to 12,650rpm, delivering a livelier top end while maintaining the smooth, linear power delivery that defines the triple character.

The Trident 660 gains a more muscular stance with new bodywork, including a redesigned, wider fuel tank and a new split seat. Chassis refinements include a revised frame and a new Showa rear suspension unit with preload and rebound adjustment, offering 130mm of travel. New wider handlebars provide greater leverage and comfort. The bike retains its 810mm seat height and 195kg kerb weight. Technology features include three riding modes, six-axis IMU with cornering ABS and traction control, a quickshifter, and cruise control. The Trident 660 is available in Cosmic Yellow, Stone Grey, and Snowdonia White.
