Triumph’s spiced up the low-capacity scene with two fresh curveballs for 2026: the Tracker 400 and the long-whispered, now fully unleashed Thruxton 400.
They share the same bones but sport very different attitudes, whilst both packing the most potent version yet of Triumph’s TR-Series single.
Let’s start with the headline figures. The familiar 398cc motor has been reworked with a revised cam profile and new tune, lifting peak power by five per cent to 42bhp at 9,000rpm. More importantly, it revs harder at the top without losing the chunky midrange that made the Speed and Scrambler 400 such easy bikes to live with.

The Tracker 400 is Triumph’s first proper nod to flat-track style, and it looks the part. Wide bars, elbows-out ergonomics, a boxy tank, number boards and a seat cowl all combine to give it real presence. It’s not just a styling exercise either. The bars are wider and lower than the Speed 400’s, the pegs are higher and further back, and the chassis is specific to the model. Suspension travel is generous, with 43mm USD forks and a preload-adjustable rear shock, while Pirelli MT60 RS tyres underline the street-tracker intent. The riding position is upright, assertive and playful — the sort that encourages you to grab a handful of throttle and enjoy the bike’s newly found appetite for revs.
Then there’s the bike everyone’s been waiting for: the Thruxton 400. If the Tracker is all swagger, the Thruxton is pure intent. Clip-ons, rear-set pegs and a low front end deliver a proper café racer stance, not just a cosmetic nod. The new fairing frames a classic round LED headlight, while the bullet seat cowl and upswept silencer nail the silhouette. Underneath, it gets its own chassis and sportier suspension tune, plus sticky Pirelli Diablo Rosso IV tyres… a clear sign this one’s meant to be ridden hard, not just parked outside a coffee shop.
Despite the differing personalities, both bikes share a solid tech package: ride-by-wire throttle, switchable traction control, ABS, torque-assist clutch and a neat analogue-digital dash setup that keeps things modern without spoiling the retro vibe. Seat heights are sensible, quality is unmistakably Triumph, and service intervals remain class-leading, backed by a two-year unlimited mileage warranty.
Pricing keeps things competitive too. The Thruxton 400 lands first in March 2026 at £5,995, with the Tracker 400 following in April at £5,745. For that money, you’re getting proper character, proper kit and two very different ways to enjoy the same brilliant little engine.
