There’s something special about the sound of a three-cylinder engine. It’s neither twin nor four, but a unique blend that delivers character you can feel in every twist of the throttle. The 2025 Triumph Trident 660 takes that legendary triple formula and wraps it in a package that’s as accessible as it is thrilling — a roadster that proves you don’t need to sacrifice fun for everyday usability.
The Trident’s 660cc triple is the heart of what makes this bike so engaging. It combines the low-down grunt of a twin with the high-revving excitement of a four-cylinder, giving you usable torque everywhere in the rev range. Whether you’re accelerating away from lights or overtaking on the open road, the power delivery is smooth, predictable, and wonderfully linear.
With the new Sports riding mode, the Trident sharpens its responses for an exhilarating experience when the mood strikes. Road mode keeps things refined for daily duties, while Rain mode softens delivery for confidence in slippery conditions. The slick gearbox pairs perfectly with Triumph Shift Assist, allowing clutchless up and down shifts that make rapid acceleration feel seamlessly effortless.
The Trident 660 punches well above its class in terms of technology. Optimised Cornering ABS and Traction Control use an advanced Inertial Measurement Unit to continuously monitor your riding, adjusting parameters in real-time for maximum performance and safety. Cruise control — once reserved for premium machines — comes standard, making longer rides more relaxed.
The easy-to-read TFT display integrates with Triumph’s My Triumph Connectivity system via Bluetooth, giving you turn-by-turn navigation, music control, and full phone functionality without taking your hands off the bars.
The Trident’s retro-modern styling is unmistakably Triumph — distinctive without being derivative. Flawless attention to detail and premium build quality shine through in every component, from the all-LED lighting with self-cancelling indicators to the thoughtfully sculpted seat. Available in three striking new colours, the Trident stands apart from the crowd while maintaining the timeless proportions that make a great roadster.
The Triumph Trident 660 is perhaps the most versatile middleweight roadster you can buy. An accessible 805mm seat height, natural riding position, and light clutch make it confidence-inspiring for newer riders, while the engaging triple engine and sporty handling keep experienced riders grinning. Add 10,000-mile service intervals, a two-year unlimited mileage warranty, and the lowest servicing costs in its category, and the Trident proves that premium doesn’t have to mean expensive. Whether you’re navigating city traffic or finding your flow on weekend rides, the Trident 660 simply does it all.
