Triumph’s just unveiled the most significant updates yet to its hugely popular Trident 660 and Tiger Sport 660.
With a more powerful engine, sharper styling, and meaningful chassis upgrades, both bikes look set to tighten their grip on the middleweight market.
At the heart of both machines is a heavily revised version of Triumph’s 660cc triple, now pumping out a claimed 94bhp at 11,250rpm and 68Nm of torque at 8,250rpm. That’s a healthy 13bhp jump over the outgoing models, with the redline raised by 20 percent to a zingy 12,650rpm. More importantly for real-world riding, Triumph says 80 percent of peak torque is available from just 3,000rpm all the way to nearly 12,000rpm, promising strong, flexible drive wherever you are in the rev range.

The extra performance isn’t just a remap job. Triumph has gone deep into the engine hardware, ditching the single throttle body in favour of three individual 44mm units, one per cylinder. There’s also a larger front-mounted airbox for improved breathing and a more addictive induction howl, a reworked cylinder head with larger exhaust valves, and higher-lift cams. Cooling has been uprated too, with a larger, repositioned radiator and fan to keep temperatures in check when ridden hard or fully loaded.
A revised 3-into-1 exhaust system with an underslung silencer keeps things Euro-compliant while preserving that trademark triple soundtrack. The six-speed gearbox has also been updated with new shafts, revised ratios, and recalibrated Triumph Shift Assist, while a slip-and-assist clutch reduces lever effort and adds a layer of polish to everyday riding.
On the roadster side, the Trident 660 has been pushed further towards the sporty end of the spectrum. New bodywork gives it a more muscular stance, with a redesigned, wider fuel tank featuring sharper knee cut-outs and a new split seat setup. There’s also a revised frame and a new Showa rear shock with preload and rebound adjustment, paired with Showa 41mm USD forks up front. With a low 810mm seat height, wider bars for 2026, and a claimed wet weight of just 195kg, the Trident still promises easy-going accessibility with a noticeable bump in attitude.
The Tiger Sport 660, meanwhile, leans harder into its role as the ultimate middleweight all-rounder. New bodywork and radiator cowls give it a beefier front end and improved weather protection, while a larger 18.6-litre fuel tank boosts touring range. Suspension remains Showa front and rear, with 150mm of travel at both ends and remote preload adjustment on the shock, making it quick and easy to set up for pillion duty or luggage.
Both bikes come loaded with tech. A six-axis IMU enables Optimised Cornering ABS and traction control, three ride modes (Sport, Road and Rain) are standard, as is cruise control and Triumph Shift Assist. A colour TFT/LCD dash with MyTriumph Connectivity brings navigation, music and call control, while full LED lighting with new headlight designs sharpens the look further.
Fresh colour schemes round out the updates. The Trident 660 is offered in Snowdonia White as standard, with Cosmic Yellow and Stone Grey available as premium options. The Tiger Sport 660 gets Pure White as standard, plus striking Interstellar Blue with Mineral Grey or Silver Ice with Intense Orange.
Prices start at £8,095 OTR for the Trident 660 and £9,295 for the Tiger Sport 660, with both landing in UK dealers from March 2026. More power, more kit, and more attitude – Triumph clearly isn’t playing it safe with its middleweights anymore.
