From a press release issued By Triumph:

Triumph Motorcycles enhances its award-winning Trident 660 for 2025, fitting even more rider focused technology as standard, upgrading the suspension and introducing a choice of three bold new colours and graphic schemes.

As the only triple engine in the class, the Trident 660 delivers thrilling, exploitable performance, and its agile, confidence inspiring handling and updated retro-modern styling is now paired with best-in-class rider-focused technology. Underpinned by Triumph’s renowned premium build quality and component specification, the Trident 660 now offers riders an even more compelling package and remarkably low cost of ownership.

In response to customer demand, the Trident 660 now features a host of new equipment that is unprecedented in this class, with Optimised Cornering ABS and Traction Control, Triumph Shift Assist and cruise control all fitted as standard. The integrated TFT display and MyTriumph Bluetooth Connectivity system gives riders turn-by-turn navigation, calls and music control, and there are three rider modes, including a new Sport mode.

Triumph’s Chief Commercial Officer Paul Stroud said: “We first launched the Trident in 2020 with a unique combination of exhilarating triple performance and character, confidence inspiring handling and bold British styling. With its unrivalled overall cost of ownership on top, it proved popular with riders of all ages and experience levels, in markets across the world, and since its launch the Trident has won several major industry awards.

“The addition of this technology sets the bar for the category yet again. Building on the popularity of the bright, bold colour scheme of our special edition, the Trident Triple Tribute, we are introducing striking new colour schemes in Cosmic Yellow, Cobalt Blue, and Diablo Red, as well as the Jet Black. But the most important factor for our customers, of course, is that the Trident 660 makes every ride seriously fun.”

TRIPLE ADVANTAGE The Trident’s exhilarating performance is delivered by a flexible three-cylinder engine, which combines low-down torque with a strong midrange and an exciting top-end rush. More than 90% of peak torque is delivered from 3,600rpm to 9,750rpm. This gives the rider the best of both worlds compared to a twin or four cylinder engine, by combining the low-down pull and strong midrange of a twin with the high-revving top-end power of a four, as well as the glorious three cylinder soundtrack.

Beautifully balanced and easy to ride at all speeds, the thrilling power delivery combined with the slick gearbox and Triumph Shift Assist, makes rapid acceleration seamless and exhilarating.

ASSURED HANDLING From the natural riding position to the high-quality suspension and powerful brakes, the Trident’s neutral and easy handling is key to its appeal.

The Trident 660’s accessible seat height of 805mm and overall narrow width makes for confident feet-down manoeuvres and low-speed riding while its innate natural balance, smooth slip and assist clutch and super-clean power delivery, are ideal for busy urban environments.

The Trident 660 delivers excellent control from the high specification Showa 41mm upside down forks which have been upgraded with Showa’s SFF-BF ‘big piston’ damping for even more comfort and control. There’s also a preload adjustable RSU, also from Showa, powerful Nissin brakes with twin 310mm discs, and grippy Michelin Road 5 tyres.

RIDER FOCUSED TECHNOLOGY New for 2025, the Trident 660 now has a class-leading level of technology, now fitted as standard. Unique in this segment, Optimised Cornering ABS and Traction Control ensures the optimum performance at all lean angles. Using information from the six axis Inertial Measurement Unit (IMU) to calculate lean angle, brake pressure and throttle position, the system continuously monitors and adjusts engine and braking parameters to ensure optimum performance and safety under braking and acceleration. Fitted as standard, Triumph Shift Assist allows seamless up and down gear changes without using the clutch, and Cruise Control is included to reduce rider fatigue.

Integrated into the instrument dial, a full-colour TFT screen with Bluetooth connectivity adds turn-by-turn navigation and full phone functionality to deliver unrivalled levels of rider convenience. In addition to the existing ride by wire throttle and Road and Rain riding modes, there’s now a third ‘Sport’ mode giving even more responsive and exciting performance from the triple engine. Increasing safety and reliability while eliminating maintenance, the Trident 660 has a distinctive round all-LED headlamp, integrated rear light and self-cancelling indicators for enhanced visibility.

UNIQUE STYLING The Trident’s unique retro-modern styling, and Triumph’s flawless attention to detail throughout, sets it apart from the pack. Its minimal lines and unmistakable muscular stance have been enhanced for 2025 with three bold new colour and graphics schemes. Cosmic Yellow, Cobalt Blue, and Diablo Red catch the eye, complemented by touches of Sapphire Black and striking diagonal white stripes. There is also a more subtle Jet Black colour scheme. Other subtle updates include upgraded materials and finishes, including a new forged aluminum top yoke and forged aluminium brake pedal.

EASILY CUSTOMISABLE With 45 Genuine Triumph Accessories to choose from, riders can add protection, comfort, styling, luggage and security to their Trident 660. From heated grips and scrolling indicators to enhance the everyday commute, to preparing for longer trips with a tail pack and tank bag and flyscreen, customers can use the Triumph Configurator to create their own style.

With an A2 restrictor kit available in European markets, the Trident 660 can be restricted to meet the requirements of the A2 category licence for younger and new riders. When the owner progresses to a full A licence, the dealer can restore full power, ready for the next stage of the rider’s journey.
