Chassis refinements and improved ride quality for both models, with a revised frame and new Showa rear suspension unit for the Trident 660 
Triumph is taking its popular Trident 660 and Tiger Sport 660 to the next level with significant updates to both models. These updates deliver more performance, making the Trident 660 a much sportier choice, and improving the touring capability of the Tiger Sport 660 with added character and excitement. 

At the heart of the upgrade is a major engine enhancement. Both models now feature a higher performance 660cc triple engine, producing an impressive 94 HP and 50 ft-lb of torque. This step up in power puts the Trident 660 at the top of middleweight roadster class, while the Tiger Sport 660 combines its new performance with improved touring capability for riders who want to go further, asserting its position as the ultimate all-around middleweight.

The updates don’t stop at the engine. The Trident 660 gains a more muscular stance with new bodywork and a chiseled fuel tank, reinforcing its athletic roadster attitude. The Tiger Sport 660 introduces a larger 4.9-gal (18.6-liter) fuel tank and new bodywork including updated radiator cowls, improving range and weather protection on long rides.

Both models retain their agile, confidence-inspiring handling, now complemented by chassis refinements and improved ride quality. The Trident 660 benefits from a new Showa rear suspension unit for improved adjustability. The Tiger Sport 660 retains its accessible ergonomics and low seat height, ensuring comfort for everyday riding and long-distance touring. 

The latest updates to the Trident 660 and Tiger Sport 660 are complemented by bold new color schemes and graphics that enhance their distinctive styling. For the Trident 660, the vibrant Cosmic Yellow and Stone Grey take center stage as premium paint options.

The Tiger Sport 660 introduces Interstellar Blue with Mineral Grey alongside Silver Ice with Intense Orange as its striking new color options. These fresh designs give riders great options to personalize their bike while maintaining Triumph’s premium finish and attention to detail. 

Updated 660cc triple engine 

 Both the Trident 660 and Tiger Sport 660 benefit from the higher-performance version of Triumph’s 660cc Triple, achieved through a series of mechanical changes and a new engine tune. Peak power is now 94 HP at 11,250 rpm, an increase of 13.8 HP, with the redline raised by 20% to 12,650 rpm for a livelier top end. Torque also sees an uplift to 50.2 ft-lb (68 Nm) at 8,250 rpm, with 80% of that available from 3,000 rpm right through to almost 12,000 rpm, ensuring strong and flexible performance across the rev range.

This combination makes the Trident 660 sportier and more engaging, while the Tiger Sport 660 offers added touring capability, whether riding two-up or fully loaded.

A key part of the performance upgrade comes from significant changes to the engine hardware, including a move from a single throttle body to three individual 1.73 in. (44mm) throttle bodies, one for each cylinder. This update further enhances the sporty nature of Triumph’s three-cylinder design, delivering the ideal balance of strong low-down torque with even more mid-range and top-end power. These changes work in harmony with the new engine tune to provide riders with a more responsive and characterful experience across the rev range.

Further enhancing performance and responsiveness, the engine benefits from a larger, front-mounted airbox that improves airflow and delivers a more engaging induction sound. The cylinder head has also been re-engineered with larger exhaust valves and a higher-lift cam profile to optimize combustion and power delivery. To manage the increased performance, the cooling system has been upgraded with a larger, repositioned radiator and fan, maintaining efficient temperature control even in demanding riding conditions. 

Completing the performance package is a new engine tune that brings a series of refinements. Alongside the increased torque and raised redline, the calibration has been optimized for smoother low-RPM throttle openings and improved overall throttle response. These changes ensure the Trident 660 and Tiger Sport 660 deliver accessible and predictable performance with added excitement across the rev range.

The performance upgrades are complemented by a series of key component revisions. The exhaust system now features a 3-into-1 header design with a revised catalyst and an underslung silencer, contributing to both efficiency and the distinctive Triple sound.

The six-speed gearbox has been updated with new input and output shafts, revised gear ratios and final drive, plus recalibrated Triumph Shift Assist for smoother, more precise changes. A new slip and assist clutch further enhance ease of use, reducing lever effort and improving control for everyday riding and longer journeys. 

Paul Stroud - Chief Commercial Officer, Triumph Motorcycles 
“Both the Trident 660 and Tiger Sport 660 have built a huge following worldwide, attracting riders of all ages and experience levels, from those new to motorcycling to experienced riders. The Trident 660 has also brought more female riders to Triumph than any other model in our line-up. These bikes have won multiple awards and introduced a new group of riders to the Triumph brand. 

“For 2026, we’ve taken both bikes to the next level. The result is a significant performance increase, which puts the Trident 660 back at the top of its class and secures the Tiger Sport 660’s position as the segment leader. Alongside this, both models gain important chassis and styling updates that enhance their presence and capability, while retaining the accessibility that have made them so popular. 

“The Tiger Sport 660 sits within the Adventure Sport-Touring segment, appealing to riders who want a versatile bike for commuting during the week, fun riding at weekends, and longer touring trips – often two-up and fully loaded. The Trident 660, on the other hand, is a middleweight roadster that has become a favorite for riders looking for an agile, stylish machine for urban riding and spirited back-road fun. These updates ensure both models continue to deliver exactly what their riders value most, with even more performance and refinement.”
