When we first published this article in 2016, the Bonneville T100 had just received the liquid-cooled 900 cc engine and made 55 hp. Ten years later, Triumph has given it a thorough update for 2026. It still looks like the classic Bonneville, true to the 1959 original, but it now makes 65 hp and carries the electronics of a modern bike.
The T100 is the most accessible Bonneville in the range: lighter and cheaper than the 1,200 cc T120, with a low seat and A2 license compatibility. It is also one of the builders' favorite bikes for a cafe racer, scrambler or brat.
What's new on the 2026 T100
The changes aim to add safety and comfort without touching the classic style:
- Cornering ABS and traction control: both systems take lean angle into account and adjust braking and power even when the bike is leaned over.
- Road and Rain riding modes: Rain softens power delivery for wet roads.
- LED headlight: it keeps the classic round shape, now with a daytime running light and better reach at night.
- New clocks: analog speedometer and rev counter with screens showing gear position, riding mode and range.
- KYB suspension and Nissin caliper: 41 mm cartridge fork, twin rear shocks and a front caliper with more bite.
- Michelin Road Classic tires on 18 and 17 inch spoked wheels.
- USB-C socket under the clocks and new round decals on the side panels.
The engine: 900 cc with plenty of low-down torque
The 900 cc parallel twin with a 270° crank is still the heart of the bike. It makes 65 hp at 7,000 rpm and 80 Nm at 3,750 rpm. That is 10 hp more than the 2016 T100, but what matters is that most of the torque is available very low: the bike pulls hard from idle and you don't need to rev it.
The clutch is assisted and slipper type, so it is light at the lever and stops the rear wheel from locking on hard downshifts. The gearbox still has five speeds. Triumph quotes 3.9 l/100 km and service intervals of 16,000 km or one year, very long for a bike of this type. It meets the Euro 5+ standard.
Chassis and equipment
The frame is still a tubular steel twin cradle, like the classic Bonnevilles. Seat height is 790 mm and the wide, flat bar gives an upright, relaxed posture. At 228 kg wet it is not light, but the weight sits low and it is easy to handle at low speed.
Up front there is a single 310 mm disc with a two-piston Nissin caliper, and a 255 mm disc at the rear. The tank holds 14.5 liters, good for about 350 km at that consumption. Cruise control is available as an accessory.

If the previous version is fine for you, Spanish dealers are selling the last 2025 units from €10,595, with a €1,000 discount on bikes registered by 30 November 2026. Note that the 2025 bike does not have cornering ABS or riding modes.
For the A2 license, Triumph dealers fit a kit that limits power to 35 kW, and it can be removed once you get your full license. Triumph also offers more than 100 accessories for the Bonneville: seats, turn signals, bags, panniers, crash bars and more.
What about the 2027 T100?
So far Triumph has not announced any changes to the T100 for 2027: the 2026 version is the one on sale and it is expected to carry over next year. The new Bonneville for 2027 is a different bike: the Bonneville T40, an entry-level version with a 400 cc single that will reach dealers in spring 2027. If Triumph announces anything new for the T100, we will update this article.
What we like and what gives us pause
We like that Triumph has added the electronics it was missing without spoiling the design: cables and sensors are still hidden and the LED headlight keeps its classic shape. The engine is very pleasant for everyday riding and A2 compatibility opens it up to many more riders. The 16,000 km service intervals and the 4-year warranty also keep running costs down.
What gives us pause is the weight, 228 kg, which you notice when pushing it around, and that it still has five gears and a single front disc. It has also gone up by about €1,000 compared with the previous version, which is now discounted. If you don't mind missing cornering ABS, a 2025 bike is a good buy.
A great base for a cafe racer
The T100 is one of the most popular bases for a cafe racer: a characterful engine, a simple tubular frame and plenty of aftermarket parts. If you are going to convert one in Spain, these are the modifications to check first, always case by case and depending on your registration document:
- Handlebar: clip-ons or a low bar change the riding position and the steering lock.
- Exhaust: new silencers must be type-approved and meet the noise limits.
- Subframe: a solo tail or a shortened subframe affects the passenger seat.
- Headlight: a smaller headlight or a new fairing needs approval.
- Turn signals and taillights: type-approved and fitted where the rules say.
- Wheels and tires: changing sizes means updating the registration document.
This is general guidance and does not replace the judgment of the ITV (the Spanish roadworthiness test) station. Find out how legalizing modifications works or tell us about your bike (both in Spanish). In the shop you will find parts and accessories for the Bonneville. And if you need ideas, take a look at the T120 scrambler by FCR Original or the Bonneville street tracker by Mule Motorcycles.
