Medium-sized vehicles get a new three-cylinder engine set-up, advances in the chassis, renewed look and more complete technological package
Triumph has announced a deep update to the 660 line in 2026, more specifically to the Trident 660 and Tiger Sport 660 models. The two motorcycles, focused on road use, receive the most comprehensive package of evolutions since launch, highlighting the new engine set-up, chassis revisions, chassis improvements and visual updates.

The main advance is in the 660 cm³ three-cylinder engine, now tuned to deliver 95 hp at 11,250 rpm and 6,9 kgf.m of torque at 8,250 rpm. The new configuration also raises the rev limit by 20%, reaching 12,650 rpm, and maintains 80% of the available torque from 3,000 rpm, ensuring consistent responses throughout the rev range.
Mechanical improvements also include the adoption of three individual 44 mm throttle bodies, a new front airbox with greater volume, revised cylinder head with larger exhaust valves and camshaft with greater lift.
The cooling system was reinforced with a larger radiator and fan, while the exhaust received a revised 3-in-1 manifold, updated catalytic converter and muffler under the engine. The six-speed transmission has undergone recalibration, with new ratios, updated axles, refined Triumph Shift Assist quickshifter and new assist and slipper clutch, which reduces lever effort.
In addition to the engine, Triumph made important adjustments to the chassis. The Trident 660 debuts a revised frame and a new Showa rear suspension, now with greater adjustability, complemented by the 41mm USD front forks. The Tiger Sport 660 maintains its balanced proposal, with extended travel Showa suspension, remote preload adjustment at the rear and ergonomics aimed at comfort over long distances.
Visually, both models received new bodywork and updated graphics. The Trident 660 adopts a redesigned, wider and sculpted tank, reinforcing its sporty stance. The Tiger Sport 660 gains revised front fairings, better aerodynamic protection and a larger tank, with a capacity of 18.6 liters, expanding the range.
In the field of technology, the two bikes have an electronic throttle, three riding modes (Sport, Road and Rain), traction control and ABS with cornering performance thanks to the six-axis IMU, cruise control as standard and a mixed TFT/LCD panel with MyTriumph connectivity, which allows turn-by-turn navigation, call control and music. The full LED lighting, with new headlights and integrated daytime running lights, reinforces the visual identity and safety.
According to Paul Stroud, commercial director of Triumph Motorcycles, the 2026 updates put the Trident 660 back at the top of the category and consolidate the Tiger Sport 660 as one of the references among versatile medium displacements, while maintaining accessibility and compatibility with the A2 license, factors that helped popularize both models globally.
In the European market, the Trident 660 starts at £8,095 and the Tiger Sport 660 at £9,295, with it arriving at dealerships scheduled for March 2026. Both have maintenance intervals of 16,000 km and a two-year warranty with no mileage limit.
For Brazil, nothing has been made official yet, and the country continues with previous versions of the models.
