Triumph Trident 660

What’s new on the 2026 Trident 660?

Triumph calls it the biggest update since launch. The engine gets three 44 mm throttle bodies (instead of one), a revised cylinder head and a new exhaust: it goes from 81 to 95 hp, and from 64 to 68 Nm. According to Triumph, 80% of the torque is available from 3,000 to almost 12,000 rpm. The gearbox gets new ratios and a new slip-and-assist clutch.

The chassis evolves too:

• a revised frame and a Showa shock now adjustable for preload and rebound;
• a wider tank, a split seat and wider handlebars;
• a new headlight with daytime running light.

The electronics carry over from the 2025 model year: cornering ABS and traction control, up-and-down quickshifter, cruise control and three riding modes, all standard. Weight rises from 190 to 195 kg wet.

How much does it cost?

Triumph France lists the Trident 660 at €8,295 in Snowdonia White. The yellow and grey colours cost extra (£150 in the UK according to Triumph). An A2 restriction kit is available as an accessory. In the US it is listed at $8,745.

How good is the engine?

The 660 cc triple (74 x 51.1 mm) with a 240-degree firing order makes 95 hp at 11,250 rpm and 68 Nm at 8,250 rpm. It is the unanimous highlight of the tests: MCN calls it “an absolute peach”, Visordown one of the most entertaining engines in the segment. MCN notes it is easier to exploit thanks to a smoother throttle response, but less playful than some rival twins.

How does it ride?

The chassis is still rated sound and agile. The reservations concern:

• a non-adjustable fork that dives or bottoms out under hard braking (MCN, Moto-Net, Motorcycle.com);
• front brakes lacking bite and ABS considered intrusive (Motorcycle.com, Moto-Net);
• increased weight, heavier than several rivals (MCN);
• ageing instruments (Visordown, Moto.it, BikeSocial).

Fuel consumption and maintenance

Triumph quotes 4.9 L/100 km; 1000PS recorded about 5.7 L/100 km on the on-board computer while riding hard. With 14 litres, range is roughly 245 to 285 km. The owner’s handbook specifies a service every 16,000 km or every year, and a valve clearance check every 32,000 km.

Recalls

No recall concerns the 2026 generation to date. Two recalls affected Trident 660s built between 2020 and 2023: an ECU setting that could cause stalling, and badly machined fork caps.
