Triumph Tiger Sport 660 (2026) – Technical Review

Like the revamped-for-2026 Trident 660 the updated Triumph Tiger Sport 660’s headline change is a massive increase in power – a full 14hp extra – to move it closer to the Tiger Sport 800 while keeping within the tightly-controlled rules around A2-class bikes.

Pair that big boost in power with a minimal increase in price and there’s no reason to believe the revamped Tiger Sport 660 shouldn’t keep its spot as one of Triumph’s most popular models in 2026.

Pros & Cons

2026 Triumph Tiger Sport 660 - Price & PCP Deals

The £9,295 list price for the 2026 Tiger Sport 660 is only £300 more than the outgoing 2025 version, which means you’re paying a 3.3% premium for 17% more power than before. That’s pretty hard to argue with and means – like the updated Trident 660 that has similar improvements – the Tiger Sport 660’s price hike is actually a little below the rate of inflation. So with some mental wrangling you can persuade yourself that buying the latest model now is costing you less, in real terms, than if you’d bought the old model a year ago.

To get that standard price you will have to limit yourself to the ‘Pure White’ version of the bike, though. If you want the more interesting ‘Interstellar Blue and Mineral Grey’ or ‘Silver Ice and Intense Orange’ two-tone schemes, you’ll be asked for another £150.

2026 Triumph Tiger Sport 660 - Engine & Performance

Getting an extra 14hp from the 660cc triple, upping its output from 80hp to 94hp in the process (81PS to 95PS, or 59.6kW to 70kW, if you prefer more European figures), would normally be a mammoth engineering task but Triumph is in the fortunate position of having a host of other three-cylinder machines in its lineup including the Daytona 660 and the Tiger Sport 800. It’s by adding elements from those bikes that the new model gets its extra performance without the cost of a clean-sheet redesign.

An in the new Trident 660 that was launched alongside the 2026 Tiger Sport 660, the big difference to the engine is the adoption of three throttle bodies – one for each cylinder – instead of the single throttle on a three-branch manifold, as used on the previous version. The Daytona 660 and the Tiger Sport 800 (and Trident 800) already have the three-throttle setup, so transposing it to the Tiger Sport 660 was significantly simplified.

It's not just the throttles, either. There’s a tweaked cylinder head with compression increased to 12:1, a bigger airbox and, of course, a new set of maps for the engine management system. The exhaust header is revised, too, while feeding into the same belly-mounted pipe as the previous Tiger Sport 660. As on the Trident, the redline rises from 10,250rpm to 12,650rpm, while peak power now arrives at 11,250rpm instead of the old bike’s 10,250rpm.

Torque rises from 64Nm (47.2lb-ft) to 68Nm (50.15lb-ft), peaking at 8,250rpm instead of the previous 6.250rpm. That 2000rpm rise in the peak torque’s position gives a clue to the extent of the new engine’s revvier nature, but Triumph says that 80% of the maximum is available from as low as 3000rpm, so it shouldn’t be gutless lower down.

As before the six-speed gearbox features a standard-fit up-and-down quickshifter and a slipper clutch, and there’s a trio of riding modes (Road, Rain and Sport) to tweak the throttle mapping and power delivery to suit your whims. The six-axis IMU means there’s cornering traction control, which is still rare in this capacity class.

The three-throttle intake system doesn’t just impact the engine: it’s wider than the single throttle arrangement of the old bike, so the main frame rails needed to be shifted to make space for the new design.

Fortunately, that’s a job Triumph had already undertaken for the Tiger Sport 800, which also has the three-throttle setup, so there were parts on the shelf to help create the 2026 Tiger Sport 660.

Like the previous-generation Tiger Sport 660, the suspension is from Showa, with 41mm upside-down, separate function forks and a preload-adjustable Showa monoshock at the back. The brakes are also carried over, with two 310mm discs and two-piston Nissin calipers at the front and a single pot caliper and 255mm disc at the rear, both ends assisted by cornering ABS thanks to the standard-fit six-axis IMU.

At 211kg the updated Tiger Sport 660 is 4kg heftier than the previous version, but the extra performance is more than worth that sacrifice.

As before, the Tiger Sport is a road-biased machine despite its ‘Tiger’ nomenclature and high riding position, with 17-inch cast alloy wheels clad in Michelin Road 5 rubber.

2026 Triumph Tiger Sport 660 - Comfort & Economy

Visually, the Tiger Sport 660’s 2026 revamp brings it closer to the Tiger Sport 800, adopting the same side panels and the larger-capacity bike’s bigger fuel tank to suit the widened frame.

That means the tank capacity increases from 17.2 litres to 18.6 litres, an 8% increase that will more than offset the fractionally worse fuel consumption of the new bike, which dips from 60.1mpg to 57.6mpg. Range, as a result of all that, rises from 227 miles to 235 miles.

The riding position and 835mm seat height are unchanged, as is the height-adjustable windscreen, with one-handed operation, that can move through an 83mm range. Heated grips and handguards are optional, as is a low seat option that brings its height down to 810mm.

The biggest visual change is the adoption of the Tiger Sport 800’s larger radiator cowl panels, which along with a tweaked frontal design are claimed to improve weather protection.

The unchanged instruments pair an LCD main display with a smaller colour TFT set inside the single dial, with MyTriumph Connectivity as standard to offer turn-by-turn navigation and control over music and calls. While not lacking in function, it’s an element of the bike that, on paper at least, looks less impressive than the bigger, full-colour screens that are increasingly common among its rivals.

Touring is likely to be a focus for many customers, and while you’ll have to pay extra for it, there are multiple luggage options including colour-matched hard cases that offer 57 litres of space, which can be upped further with a 49-litre top case.

2026 Triumph Tiger Sport 660 - Rivals

The Tiger Sport 660’s performance hike means it’s stretched a lead over some of its most natural rivals – bikes like the Kawasaki Versys 650, Yamaha Tracer 7 and Suzuki V-Strom 800RE now all lag behind it in terms of outright power. Its new output means it’s getting closer to bigger competitors like BMW’s 105hp F900XR, too, although that’s a substantially more expensive machine.

Kawasaki Versys 650 - Close to the Triumph in terms of capacity, the Kawasaki now lags a long way behind it in power thanks to the Tiger Sport 660’s 2026 revamp. It is a cheaper alternative, though, and similarly A2-compatible once restricted.

Yamaha Tracer 7 - The Tracer 7 also drops further back in terms of power, but matches the Tiger Sport 660 in terms of torque. The Y-AMT semi-auto transmission version comes in very close to the Triumph’s price tag and is the only machine in this group at the moment to offer an automated manual transmission with pushbutton control.

Suzuki V-Strom 800RE - Maybe the closest competitor to the Tiger Sport 660, the V-Strom has been leapfrogged in terms of outright power by the new version of the Triumph but still has the edge in terms of torque thanks to its larger engine. It’s a heavier bike, though, and more expensive if you pay the full list price.

2026 Triumph Tiger Sport 660 - Verdict

The previous Tiger Sport 660 was already a pretty compelling package for A2 licence holders, and the new version has the advantage of still being appealing once you’ve graduated to a full ‘A’ licence – just get the A2 kit removed by a dealer and the power is doubled. Looking at the rivals in its class and there are few machines that offer the same performance-to-price balance, and none with the charisma of a three-cylinder engine.
