Triumph Trident 660

From a press release issued By Triumph:

Triumph is taking its popular Trident 660 and Tiger Sport 660 to the next level with their most significant updates yet. These updates deliver more performance, making the Trident 660 a much sportier choice, while the Tiger Sport 660 delivers character and excitement, while also improving its touring capability.
At the heart of the upgrade is a major engine enhancement. Both models now feature a higher-performance 660cc triple engine, producing an impressive 95PS and 68Nm 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 middleweight all-rounder.

The updates don’t stop at the engine. The Trident 660 gains a more muscular stance with new bodywork and a chiselled fuel tank, reinforcing its athletic roadster attitude. The Tiger Sport 660 introduces a larger 18.6-litre 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, while 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 colour schemes and graphics that enhance their distinctive styling. For the Trident 660, the vibrant Cosmic Yellow and Stone Grey take centre stage as the premium paint choice, with Snowdonia White offered as standard.

The Tiger Sport 660 introduces Interstellar Blue with Mineral Grey alongside Silver Ice with Intense Orange as its striking new premium options, and the standard option, Pure White. These fresh designs give riders even more ways to personalise 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 95 PS at 11,250 rpm, an increase of 14 PS, with the redline raised by 20% to 12,650 rpm for a livelier top end. Torque also sees an uplift to 68 Nm at 8,250 rpm, with 80% of that available from 3,000 rpm right through to almost 12,000 rpm, ensuring strong, 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 – all while retaining easy, accessible performance and A2 licence compatibility.

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 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 optimise combustion and power delivery. To manage the increased performance, the cooling system has been upgraded with a larger, repositioned radiator and fan, ensuring 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 optimised for smoother low-RPM throttle openings and improved overall throttle response. These changes ensure the Trident 660 and Tiger Sport 660 deliver accessible, 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 enhances ease of use, reducing lever effort and improving control for everyday riding and longer journeys.

Paul Stroud, Chief Commercial Officer, Triumph Motorcycles, said: “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 and A2 licence compatibility 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 favourite 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.”

TRIDENT 660 – TRIPLE THE THRILL
The new Trident 660 combines thrilling performance, agile handling, rider-focused technology, and distinctive muscular styling with a class-leading low cost of ownership – making it the perfect entry point to the Triumph family.

Class-Leading Performance with Everyday Usability
The new Trident 660 delivers a significant step up in performance for 2026. Powered by the latest evolution of Triumph’s 660cc triple engine, it now produces 95PS at 11,250rpm – an increase of 14PS over the previous generation – and 68Nm of peak torque at 8,250rpm. With 80% of that torque available from 3,000rpm through to almost 12,000rpm, riders benefit from instant response at every twist of the throttle.

Key to this improvement is a series of internal engine changes, including the introduction of three individual 44mm throttle bodies, a larger airbox, revised cylinder head, and a new engine tune. The redline has been raised by 20% to 12,650rpm, giving the Trident 660 an even more engaging top end, while maintaining the smooth, linear power delivery that makes it easy and enjoyable to ride every day. As a triple, the Trident 660 offers the perfect combination of low-down torque, and now with even more mid and top end power, providing accessible and useable everyday performance.

The distinctive triple soundtrack remains a defining feature, now enriched by the triple throttle bodies and the enhanced induction system, complemented by a compact underslung silencer. A revised exhaust system with a 3-into-1 header and updated catalyst ensures compliance with the latest standards without compromising character.

The six-speed gearbox has been refined with updated shafts, revised ratios, and recalibrated Triumph Shift Assist for quicker, smoother gear changes. A slip and assist clutch reduces lever effort and improves control, making the Trident 660 ideal for urban riding and longer journeys. For European riders, an A2 licence conversion kit is available as an accessory, which can be fitted and later removed by a Triumph dealer, while LAMS variants are available in Australia and New Zealand.

Muscular Stance Meets Premium Finish
The 2026 Trident 660 introduces new bodywork and styling updates that give the bike a more muscular stance and athletic attitude. There is a redesigned, wider fuel tank with chiselled knee cut-outs, and a new split rider and pillion seat, with a new accessory seat cowl for solo riders. The updated headlight mount and new headlight enhance the bike’s presence. Riders can further personalise their Trident with accessory options such as a colour-coded fly screen or bar-end mirrors.

Attention to detail is evident throughout, with subtle Triumph branding on the handlebar clamp, filler cap, and integrated into the headlight and tail light. Cables and hoses are neatly hidden for a clean, premium finish.

Three contemporary colour options are available: Cosmic Yellow, Stone Grey, for an extra £150 and Snowdonia White as standard, each complemented by distinctive graphics that reinforce the Trident’s modern roadster identity.

Revised Frame and Premium Suspension
The Trident 660 retains its agile, confidence-inspiring handling, now enhanced with chassis updates for 2026. A revised frame and new Showa rear suspension unit with preload and rebound adjustment join the premium Showa 41mm USD big piston forks at the front, delivering 120mm of travel. At the rear, the new RSU offers 130mm of travel and improved adjustability, allowing riders to fine-tune their setup for a sportier roadster ride.

Lightweight cast aluminium wheels and Michelin Road 5 tyres provide excellent grip and feedback in all conditions, while twin 310mm discs with two-piston Nissin calipers deliver strong, predictable braking performance. Braided brake lines and a span-adjustable brake lever ensure consistent feel and control.
Natural ergonomics make the Trident 660 easy to ride at any speed. A low seat height of 810mm and slim standover aid slow-speed manoeuvres, while new wider handlebars for 2026 offer greater leverage and comfort. Combined with the bike’s low wet weight of 195kg, these updates reinforce the Trident’s reputation for agility and rider confidence.

Connectivity and Convenience Built In
The Trident 660 is equipped with a comprehensive suite of rider-focused technology designed to enhance safety, convenience, and connectivity. Ride-by-wire throttle enables three riding modes, Sport, Road and Rain, each optimising throttle response, ABS, and traction control settings for different conditions.

A six-axis IMU enables Optimised Cornering ABS and switchable Optimised Cornering Traction Control, providing reassurance and control at all lean angles, enhancing confidence in any riding conditions. Triumph Shift Assist allows clutchless up and down shifts, while cruise control is fitted as standard, making longer rides more comfortable.

The instrument setup combines a colour TFT display with an LCD screen, delivering clear, easy-to-read information. MyTriumph Connectivity comes as standard, enabling turn-by-turn navigation, music, and call control. Full LED lighting, including the new headlight design with integrated DRL, ensures excellent visibility and a distinctive look.
