The Triumph Trident 660 is a roadster built around a 660 cc triple-cylinder engine. For the 2026 model year, U.S. pricing starts at $8,995. Triumph positions it for everyday riding and says it suits riders of all ages and experience levels.
This guide covers the engine, chassis, features, price, and the riders it suits best. Some published figures differ slightly from one listing to the next, so confirm the current specs with a dealer before you buy.
Triumph Trident 660 Overview
Triumph describes the Trident as built for riders who live for the thrill of performance, with agile handling and a stripped-back roadster style. The same description says it is easy in the city and fun on the open road. That combination is the core of the pitch: a bike that feels playful on a twisty road but stays calm in traffic.
Triumph calls the Trident the everyday ride and the perfect entry point into the Triumph range. It is intended to compete in the middleweight sector. For you, that means a bike sized and priced for daily use, not a specialist machine with one narrow job.
Triumph Trident 660 Engine and Performance
The engine is a liquid-cooled, inline three-cylinder with 12 valves and DOHC. At 660 cc, it sits in the middleweight range. Triumph claims 95 hp at 11,250 rpm and 50 lb-ft of torque at 8,250 rpm.
Peak torque at 8,250 rpm means the strongest pull arrives in the middle of the rev range. You do not need to wind the engine to the top of the tachometer to get going. That makes around-town riding and roll-on passing more relaxed.
Published figures vary a little. One listing shows 94 hp at 11,250 rpm and 50.2 lb-ft at 8,250 rpm. The gap is small, but it is a reminder to check the current spec sheet.
Triumph Shift Assist provides clutchless up-and-down shifting. It is standard on the 2026 model. A bidirectional quickshifter is also listed for the bike. If you shift often in traffic, that combination reduces the clutch work.
A Revzilla Common Tread review says the update amplifies the triple induction howl and revised the power delivery to the rear wheel. If the intake sound matters to you, that review suggests the note is more noticeable than before.
Triumph Trident 660 Chassis and Ergonomics
The front end uses Showa 41mm upside-down separate function big piston forks with 4.72 in of wheel travel. The rear uses a Showa monoshock with preload and rebound adjustment and 5.12 in of travel. Adjustable preload and rebound let you tune the suspension for a passenger or for heavier loads.
Up front, twin 310 mm fixed discs use 2-piston sliding calipers and OCABS. The rear has a single 255 mm fixed disc with a single-piston sliding caliper. A six-axis IMU enables Optimized Cornering ABS and switchable Optimized Cornering Traction Control. The system adjusts to lean angle, which helps when you brake or accelerate mid-corner.
Here are the main chassis and ergonomic numbers for the 2026 model:
| Item | Trident 660 (2026) |
|---|---|
| Seat height | 31.9 in |
| Wheelbase | 55.2 in |
| Handlebars | 0.6 in wider than before |
| Fuel tank | 3.7 gal |
| Wet weight | 429.9 lb (195 kg) |
| Rake and trail | 24.6 degrees, 107.3 mm (4.22 in) |
| Tires | 120/70 ZR 17 front and 180/55 ZR 17 rear, Michelin Road 5 |
The 55.2 in wheelbase and 24.6 degree rake set the steering character. A 3.7 gal tank gives you a reasonable range between fill-ups, though not a touring-size capacity. The span-adjustable brake lever lets you set reach for longer rides.
Triumph Trident 660 Features
The instruments combine an LCD multifunction display with an integrated color TFT screen. The TFT handles menus and navigation prompts, while the LCD keeps core data readable at a glance. A full-color TFT with Bluetooth connectivity and turn-by-turn navigation is also listed.
The bike offers three ride modes: Rain, Road, and Sport. Sport is the new mode for the 2026 model. Each mode adjusts throttle and traction control maps, so you can match the setting to wet pavement or a fast road.
Lighting is full LED. The headlight nacelle is larger than before, and the round headlamp is a distinctive styling element. Standard equipment includes Optimized Cornering ABS and Traction Control, Triumph Shift Assist, and Cruise Control. Switchable traction control also gives you control over intervention.
Some features are options. Heated grips, TPMS, and a USB charger are listed as optional on the 2025 model. An optional Bluetooth connectivity system works with the My Triumph app for Android and Apple iOS. The passenger footpegs are listed alongside the driver’s.
Triumph Trident 660 Price and Trims
U.S. pricing for the 2026 Trident 660 begins at $8,995. That is a $440 increase over last year. Compare it with Triumph’s sibling, the Tiger Sport 660:

|---|---|---|
| Trident 660 | $8,995 | 3.7 gal |

Triumph offers 45 Genuine Triumph Accessories for the Trident 660. Listed options include a tail pack and tank bag, bar end mirrors, a flyscreen, and an aluminum bellypan. Triumph lists four color schemes: Cosmic Yellow & Sapphire Black, Cobalt Blue & Sapphire Black, Diablo Red & Sapphire Black, and Jet Black.
Service is due every 10,000 miles or 12 months. Triumph calls that a class-leading interval. Plan your maintenance budget around the interval you see on the bike’s service schedule.
How the Triumph Trident 660 Compares
Triumph names the Yamaha MT-07, Kawasaki Z650, and Honda CB650R as rivals, with the Suzuki SV650 as a lesser competitor. Those are the bikes you should put beside the Trident on your own shortlist. Compare the current price, claimed power, and seat height for each one on its manufacturer’s spec sheet.
If the MT-07 is on your list, read Yamaha MT-07 First Bike? Who It Suits and What to Know for a look at that bike’s fit for new riders. Use the same checklist for every bike you consider. Seat height, weight, and what you can afford each month matter more than brand loyalty.
Who the Triumph Trident 660 Is For (and Who Should Skip It)
The Trident suits riders who want a manageable roadster for daily use. Triumph says it suits riders of all ages and experience levels. Its 31.88 in seat height with a narrow standover helps you get your feet down at stops, which matters most for shorter riders and newer riders.
It is also a good fit if you split your riding between city traffic and weekend backroads. Triumph describes it as easy in the city and fun on the open road, and as built for riders who enjoy agile handling. If you want that playful feel without a large, heavy machine, it deserves a test ride.
Skip it if you need a bike that can run on an A2-style restricted license without modification. An A2 licence restrictor kit is offered, which means you would need to add that kit. Also skip it if you want a touring-first bike. Triumph frames the Trident around city riding and open-road fun, not long-distance touring.
