2026 Triumph Trident 660 and Tiger Sport 660 – First Look
Revised styling and a 14 hp increase over the previous models
Triumph announced updates to its middleweight platform, significantly improving the Trident 660 roadster and Tiger Sport 660 sport-tourer with changes that should make customers happy… Well, at least everyone except those who just bought last year’s models.
Both 660 models received updated electronics for 2025, including a six-axis inertial measurement unit and the lean-sensitive rider aids that come with it. While that’s still a useful update, those who bought in on the 2025 models might suffer a bit of buyer’s remorse, as the 2026 editions receive a significantly more powerful engine, a refined chassis, updated styling, and, in the case of the Tiger Sport 660, a larger fuel tank.
For 2026, Triumph made substantial mechanical and tuning changes to the 660cc Triple. The new engine now uses separate 44mm throttle bodies for each cylinder instead of the single throttle body from the previous design. This allowed Triumph to offer a better balance of low-down torque and mid- and high-end power.
Triumph also enlarged the airbox for better airflow, and redesigned the cylinder head with larger exhaust valves and higher-lift cams. The engine now redlines at 12,650 rpm, or about 20% higher than the previous engine.
The result is a claimed peak output of 95 hp at 11,250 rpm compared to the 80 hp at 10,250 rpm claimed on the previous engine. The claimed peak torque also sees a small bump up 50 lb-ft. at 8,250 rpm from 47 lb-ft. at 6,250 rpm, with Triumph claiming 80% of it is available from 3,000 to 12,000 rpm.
To manage the higher performance, Triumph added a larger radiator with a repositioned fan to keep the engine temperature at an optimum level. Triumph also revised the 3-into-1 exhaust system with a new catalytic converter and silencer.
The engine is matched with an updated gearbox employing new input and output shafts, revised gear ratios and a new final drive ratio. The bidirectional quickshifter was recalibrated accordingly, with Triumph claiming smoother, more precise shifting. A new slip and assist clutch further improves shifting control while reducing clutch lever effort.
The electronic updates added last year return. These include three selectable ride modes, cruise control, and IMU-backed Optimized Cornering ABS and switchable Optimized Cornering Traction Control.
Both 660 models also received individual changes, which we’ll describe in more detail below.
2026 Triumph Trident 660
The 2026 Trident 660 receives new bodywork resembling the look of the larger 800 model Triumph introduced last October. The fuel tank is wider than the previous design, with reshaped knee cutouts and a sharper curve up front, giving the Trident 660 a more muscular look. The LED headlight nacelle is also larger, to balance the tank’s new proportions.
Triumph replaced the previous one-piece saddle with a split rider and passenger seats, raising the seat height a smidge to 31.9 inches from 31.7 inches. The handlebars are 0.6 inches wider than before, offering more steering leverage.
The 41mm Showa Big Piston fork is unchanged, but the rear suspension uses a new monoshock that now offers adjustable rebound in addition to preload. The braking system is also the same as last year, with twin two-piston Nissin front calipers and 310mm discs up front, and a single 255mm disc and single-piston caliper for the rear.
For the U.S. market, the 2026 Trident 660 will be available in Cosmic Yellow or Stone Grey, while other markets also get a Snowdonia White option. U.S. pricing begins at $8,995; that’s a $440 increase over last year, but people have paid a lot more to get less of a performance upgrade out of their bikes.
2026 Triumph Tiger Sport 660
Visually, the Tiger Sport 660’s changes are relatively minor compared to the Trident. The most notable difference is the larger radiator shroud, which Triumph claims to offer better weather protection while helping to improve fuel mileage to 57.6 mpg compared to the 52.3 mpg claimed on the 2025 model.
For 2026, Tiger Sport 660 receives a larger 4.9-gallon fuel tank, up from the 4.5-gallon capacity of last year’s model. With the new fuel economy figures, that works out to an estimated range of about 282 miles, or 47 miles further than the 2025 version.
While the Tiger Sport 660 gets the revised frame, its suspension is unchanged from before, with its inverted Showa separate function and remote preload adjustable rear shock both offering 5.9 inches of travel. The Nissin brakes are the same as the Trident 660.
In the U.S., the 2026 Triumph Tiger Sport 660 will be offered in either Interstellar Blue & Mineral Grey, or Silver Ice & Intense Orange, but other markets will also have a Pure White color option. Pricing starts at $10,445, which works out to be a $750 increase from 2025.

The pure white on the Sport 660 is by far the best colorway here. Come on, bring it to the US!
Not sure the new styling and seat are improvements but the rest sure is. Can't believe Triumph was using a single throttle body before.
