2026 Triumph Thruxton 400 First Look: An Icon Made Accessible

Triumph has brought the Thruxton name back, but not in the form longtime fans might expect. Instead of replacing the discontinued 1,200cc Thruxton RS with another large-capacity café racer, the 2026 Triumph Thruxton 400 takes the badge into the brand’s growing entry-level Modern Classic range. It joins the Speed 400, Scrambler 400 X, Scrambler 400 XC, Tracker 400, and most recently, the Bonneville T40 and T40 Black, with its decidedly sportier brief.

The Thruxton 400 is powered by the same basic TR-Series engine architecture already used throughout Triumph’s 400 family. It’s a liquid-cooled, four-valve, DOHC single displacing 398cc, with an 89mm bore, 64mm stroke, and 12:1 compression ratio. Electronic fuel injection and ride-by-wire are standard, while a six-speed transmission sends power to the rear wheel.

Triumph has not simply dropped the standard Speed 400 tune into the Thruxton, though. The cafe racer gets the most powerful version of the TR-Series engine to date, producing 41.4 horsepower at 9,000 rpm and 27.6 lb-ft of torque at 7,500 rpm. Triumph says the revised engine has a higher rev limit and stronger top-end performance, increasing peak power by five percent compared with the earlier TR-Series tune.

This Is More Than A Speed 400 Wearing A Fairing

Visually, the Thruxton 400 goes much further than adding a windshield and changing the paint. The bike features a modern half-fairing surrounding its round LED headlight, a sculpted fuel tank, a removable color-matched bullet-style seat cowl, an upswept silencer, and clip-on handlebars. Rear-set footpegs complete the more committed cafe-racer riding position, while the passenger portion of the seat remains usable once the cowl is removed.

Owners will find a 43mm upside-down Showa Big Piston fork offering 5.31 inches of wheel travel, while the rear uses a gas monoshock with an external reservoir, preload adjustment, and 5.12 inches of travel. Triumph says the suspension has specifically been calibrated around the Thruxton’s sporty ergonomics rather than simply relying on appearance to distinguish it from the Speed 400.

The Thruxton rolls on 17-inch cast-aluminum wheels wrapped in Pirelli Diablo Rosso IV tires. Braking hardware consists of a single 300mm front disc with a four-piston radial caliper and a 230mm rear disc with a single-piston floating caliper. ABS is standard.

Electronics are kept relatively straightforward. The bike features electronic throttle control, switchable traction control, ABS, all-LED lighting, and an analog speedometer paired with an integrated multifunction LCD display. There are no elaborate riding modes or IMU-based rider aids here, which keeps the electronics package in line with the rest of Triumph’s accessible 400 lineup.

The Thruxton Name Now Has A Much Lower Entry Price

The Thruxton 400 occupies an interesting position within Triumph’s Modern Classic lineup. It provides a more focused alternative to the upright Speed 400 without requiring buyers to step into a much larger, heavier, and more expensive twin-cylinder model. The cafe-racer styling is backed by meaningful changes to the ergonomics, suspension setup, tires, and engine calibration, so this isn’t simply a cosmetic exercise.

At $6,295, it also gives riders an accessible route into the Thruxton name after the departure of the 1,200cc Thruxton RS. What buyers are getting is very different from that motorcycle, of course, but the combination of decent power, accessible weight, and respectable hardware makes the Thruxton 400 one of the more specialized members of Triumph’s small-displacement family.
