Triumph Bonneville T100

Which Bonneville T100 for 2026?

The Bonneville T100 is Triumph’s entry-level Bonneville: the same silhouette as the T120, but with the liquid-cooled 900 ‘High Torque’ twin, a single front disc and a five-speed gearbox. The 2026 model year, in dealerships from February 2026, evolves the generation launched in 2021: an IMU running cornering ABS and traction control, two riding modes (Road and Rain) new to the T100, an LED headlight with daytime running light, a USB-C socket under the clocks, Euro 5+ homologation, KYB suspension, a Nissin front caliper and new colours with a hand-painted gold coachline.

Triumph France is still selling previous-generation T100s, listed as ‘previous model year’: from €11,595, and €12,595 for the 2025 Icon Edition. They lack the 2026 updates.

How much does it cost?

The 2026 T100 comes in a single version. It costs €11,695 in Stone Grey, its standard colour, and €12,295 in the two two-tone schemes, Jet Black / Diablo Red and Snowdonia White / Sapphire Black. In the UK it starts at £9,695; in the United States, at $11,495, $500 more than the outgoing model according to RevZilla.

The T100 requires a full A licence, but an official A2 restrictor kit, fitted by Triumph dealers and reversible, allows it to be ridden on an A2 licence. Triumph France publishes neither its price nor the exact restricted output. Cruise control is an accessory: MCN quotes £283.26 in the UK; its French price is not published.

How good is the engine?

The 900 cc parallel twin (84.6 x 80 mm), with a single overhead cam, 8 valves and a 270° crank, makes 65 hp (47.8 kW) at 7,000 rpm and 80 Nm at 3,750 rpm. Triumph quotes the same power as in 2021, but at 7,000 rpm instead of 7,400. The gearbox has five speeds, the clutch is a slip-and-assist unit and final drive is by chain.

Moto.it describes an engine that is full from low revs, never abrupt, and whose 65 hp are enough; Visordown finds it full of character and free of vibration. Motorcycle.com finds the sound and engine feel surprisingly close to the T120’s. MCN and Moto.it miss a sixth gear, and Moto.it notes high revs and vibration at sustained motorway speeds.

How does it ride?

The T120’s tubular steel twin-cradle frame carries a 41 mm KYB cartridge fork and twin KYB shocks adjustable for preload. Braking relies on a 310 mm fixed disc gripped by a Nissin two-piston floating caliper at the front and a 255 mm disc at the rear. The 32-spoke wheels (18-inch front, 17-inch rear) wear Michelin Road Classic tyres. Triumph publishes neither suspension travel nor ground clearance.

Visordown finds the suspension perfectly judged; MCN, writing about the previous generation, finds it basic and notes it is often the first thing owners upgrade. The front brake is the most widely shared criticism: Visordown wants more bite and RevZilla finds it lacklustre; Moto.it finds it adequate for normal use but advises braking slightly earlier when riding briskly. The official weight is 228 kg wet; the 2026 press kit gives 233 kg, the T120’s figure, which Visordown repeated.

What electronics does it have?

Ride-by-wire allows two modes, Road and Rain, which act on throttle response and traction control; Visordown finds Rain mode too restrictive in the dry. Traction control can be switched off temporarily; ABS cannot be disabled. The instruments stay true to the style: twin analogue clocks with LCD screens (range, gear position, riding mode). There is no TFT screen, no smartphone connectivity and no quickshifter.

Who is it for?

With its 790 mm seat, wide handlebars and docile engine, the T100 targets riders who want a genuine Bonneville without the displacement or price of the T120 (€14,595), including A2 licence holders thanks to the kit.

Fuel consumption and maintenance

Triumph quotes 3.9 L/100 km (92 g/km CO2), giving a theoretical range of about 370 km from the 14.5-litre tank. No review has published a measured figure for the 2026 model year. The owner’s manual calls for an oil change every 16,000 km or every year and a valve clearance check every 32,000 km. The warranty is 2 years with unlimited mileage.

Recalls

No recall affects the 2026 model year (NHTSA, RappelConso, as of 12 October 2026). Known recalls concern older T100s: alternator wiring that may overheat (built until December 2023) and electrical wiring in 2019 (2017-2020 generation).

The generations

The Hinckley-era T100 first used an air-cooled 865 cc twin, with carburettors and then fuel injection from 2008. In 2017 it adopted the liquid-cooled 900; the 2021 generation added 10 hp, and the 2026 model year IMU-based electronics.
