Tiger Sport and Trident 660: More power, new chassis, revised styling
Triumph two of its 660cc triples, revising the chassis and sharpening the focus of both the 2026 Trident 660 and Tiger Sport 660.
Triumph has given its 660cc road range a proper overhaul for 2026, with the Trident 660 and Tiger Sport 660 both receiving their most substantial updates since launch. While the styling tweaks are obvious at a glance, the real story sits under the bodywork, where a heavily revised triple engine and chassis updates headline the update.
Both bikes now make 95PS (93.7 bhp) and 68Nm (50.1 lb ft) from Triumph’s 660cc triple, a jump of 14PS (10 bhp) over the outgoing versions. But this isn’t just a remap job. Triumph has made meaningful mechanical changes to the engine, raised the redline, revised the gearbox and altered the chassis to suit. On paper at least, these are more than token updates.
What’s new with the 2026 Trident 660
The updated 660 triple is shared by both bikes and has been reworked from intake to exhaust. The biggest change is the move from a single throttle body to three individual 44mm throttle bodies, one per cylinder. That makes the engine from both bikes pretty much identical to the one found in Triumph’s Daytona 660 - which also runs a three inlet engine. That’s backed up by a larger, front-mounted airbox, a revised cylinder head with larger exhaust valves, and a higher-lift cam profile.
Peak power now arrives at 11,250rpm, with the redline lifted to 12,650rpm. Torque rises to 68Nm at 8,250rpm, and Triumph claims 80 per cent of that is available from 3,000rpm through to almost 12,000rpm. Cooling has also been upgraded with a larger, repositioned radiator and fan to cope with the extra performance.
The exhaust system has been reworked too, using a new 3-into-1 header design, revised catalyst and underslung silencer. A slip-and-assist clutch is now fitted, and the six-speed gearbox gets new shafts, revised ratios and updated Triumph Shift Assist calibration.
The Trident 660 benefits most obviously from the extra power. With the same lightweight roadster brief as before, the added top-end performance and higher rev ceiling should give it a noticeably sportier edge.
Triumph hasn’t left the chassis alone either. The steel frame has been revised to suit the updated engine. From talking to Triumph, the new frame has had to be adapted to accept the new wider throttle bodies. The geometry of the bike remains exactly as before. There’s a new Showa rear shock with preload and rebound adjustment, while the front suspension remains as before, with Showa 41mm USD forks. The 2026 Trident 660 provides 120mm of travel at both ends of the bike. Wheels, brakes and tyres are unchanged, with Michelin Road 5s and twin 310mm discs up front, mated to two-piston Nissin calipers. Ergonomics have been subtly altered with wider handlebars, while the seat height remains a manageable 810mm. The wet weight for the bike remains at 195kg.
The final change for 2026 is the styling, with Triumph aiming to make the new Trident 660 a bit more muscular. Bodywork has been redesigned around a wider, more sculpted fuel tank and a new split seat.
Electronics carry over largely intact, with ride-by-wire, three riding modes, a six-axis IMU enabling cornering ABS and traction control, standard cruise control and a TFT/LCD dash with MyTriumph connectivity. A quickshifter for the Trident 660 is still available, but only as an option.
What’s new with the 2026 Tiger Sport 660
The Tiger Sport 660 gets the same engine upgrades, but the focus here is less about outright sportiness and more about maintaining performance when loaded up. The extra power and torque should be more noticeable when riding two-up or touring.
Chassis changes mirror the Trident’s in terms of frame revision, as does the suspension - albeit with the Tiger Sport 660 allowing for 150mm of travel front and rear. The Showa rear shock keeps its remote hydraulic preload adjuster, which remains one of the Tiger Sport’s most useful real-world features.
The most practical update for 2026 is the larger 18.6-litre fuel tank, up from the previous bikes 17.2 litre item. The new tank should mean a usable range of more than 200 miles. New radiator cowls and revised front bodywork aim to improve weather protection, while the adjustable screen can still be adjusted with just one hand.
The rest of the bike remains as before, with the braking hardware, and the electronics package mirrors the Trident’s, including IMU-assisted rider aids, cruise control and connectivity as standard.
