Street tracker and cafe racer options added to Triumph 400s UK range
A new flat-tracker and a revived cafe racer give Triumph’s 400 platform fresh attitude – and the most powerful engine tune yet.
Triumph has expanded its small-capacity line-up once again, adding two new models to the 400 platform: the flat-track-inspired Tracker 400 and the cafe racer-leaning Thruxton 400.
Both use a revised version of the 398cc TR-Series engine, with a raised rev limit and a new claimed 41.4bhp output – five per cent more peak power than the Speed 400 and Scrambler 400 X.

Tracker 400 – flat-track stance, on-road intentions
The Tracker 400 isn’t pretending to be a city scrambler or a commuter dressed up as something else. It’s a stripped-back road bike with flat-track bodywork, complete with number boards, and ergonomics that push the rider forward. Triumph has fitted bars that are 23mm wider and 134mm lower than on the Speed 400, with footpegs mounted 86mm further back and 27mm higher. The result is a taller-in-the-shoulders posture designed to look and feel more “elbows out”.
The chassis has been tweaked for the riding style, too. There are 43mm USD big-piston forks, a preload-adjustable gas monoshock, and Pirelli MT60 RS tyres on dual-spoke wheels. There’s no off-road pitch here, despite the tread pattern – the focus is sporty road handling, aided by radial four-piston calipers and ABS.
The rest of the styling leans heavily into the flat-track theme: seat cowl, front number board, boxy tank, and three paint options with race-influenced graphics. None of it is subtle, but that’s kinda the point. Paint options are Aluminium Silver Gloss, Racing Yellow, and a Phantom Black option that combines moody black with Dark Silver, Vanilla White, and Pearl Metallic White accents across the tank - this is the one we’d go for! Each paint scheme is paired with decals that are tailored to fit with the colour.
Thruxton 400 – the famous cafe racer name returns
The bigger news, at least for Triumph fans, is the return of the Thruxton name. Rather than a scaled-down homage to the 1200 Thruxton that bowed out in 2024, this 400 feels more like a starter kit for future cafe racer lovers. Clip-on bars, higher rear-set footpegs and a fairing-equipped round headlight all work together for a sportier silhouette. The riding position is much sharper than the Speed 400, with bars 40mm narrower and nearly 250mm lower. It’s probably feel much more spritely in the corners, thanks to the extra weight over the front, but it might not be the 400 of choice from Triumph if you spend your riding days schlepping up the motorway!
The suspension package mirrors the Tracker in most places but swaps tyre choice for Pirelli Diablo Rosso IV rubber, reflecting its more focused intent. The still-compact chassis offers a middle ground between commuter comfort and retro-sport poise, and Triumph clearly wants young riders to feel like they’re on something with heritage, not just a budget beginner bike.
Four colours are available: Phantom Black and Aluminium Silver, Carnival Red Gloss with Aluminium Silver, Pearl Metallic White and Storm Grey, and a Metallic Racing Yellow with Aluminium Silver design.
What the Tracker 400 and Thruxton 400 share
Alongside the revised 42PS engine, the two bikes use the brand’s now-common mix of modern tech wrapped in old-school styling: switchable traction control, ride-by-wire throttle, torque-assist clutch, ABS, and a single analogue-plus-LCD dial. Service intervals remain lengthy for the class, and both come with a two-year unlimited mileage warranty that includes accessories.
Triumph is also leaning hard on factory extras. There’s a quilted seat for the Thruxton, bar-end mirrors, bullet indicators and the usual crash protection, all designed to bolt straight on without looking too aftermarket.
Triumph Tracker 400 and Thruxton 400 UK price and availability
The idea for both bikes is simple enough, but it seems like it's been executed in Triumph’s usual perfect fashion - and the inclusion of a Thruxton-named, cafe racer-styled bike to the range is a total no-brainer. These two are aimed squarely at riders who want more attitude than outright practicality. They’ll sit alongside the existing 400 range, with the Tracker in dealerships from April 2026 at £5,745, and the Thruxton arriving slightly earlier in March at £5,995.
