Triumph Tracker 400: What’s New?
The Tracker 400 joins the Speed 400 and Scrambler 400 in Triumph’s lineup and has been unveiled alongside the Thruxton 400 in the UK. While it shares the TR-Series engine and the Scrambler’s exhaust end-can, the Tracker 400 differs significantly in terms of design, dimensions and rider ergonomics. Mechanically, it is more closely related to the Speed 400.
Power comes from a 398cc single-cylinder, liquid-cooled engine that delivers 42hp at 9,000rpm, which is 2hp more than the Speed 400. Torque output remains unchanged at 37.5Nm, and the engine is paired with a 6-speed gearbox.
In terms of weight, the Tracker 400 tips the scales at 173kg (kerb), making it 3kg heavier than the UK-spec Speed 400. It features a slightly sharper 24.4-degree rake angle, compared to the Speed’s 24.6 degrees. The motorcycle rides on 17-inch wheels front and rear, with a 150-section rear tyre.
The seat height has been increased to 805mm, offering a more commanding riding position compared to the Speed 400’s 790mm. Braking hardware remains unchanged, with a 300mm front disc and a 230mm rear disc.
Visually, the Triumph Tracker 400 stands out with its flat-track-inspired design, featuring a boxy fuel tank, compact flyscreen, number-board-style side panels and a colour-matched seat cowl. The rear section, including the rectangular LED tail-lamp and seat design, appears to be shared with the Thruxton 400.
Although the Tracker 400 has been unveiled in the UK, it is unlikely to be launched in India, as per current indications.
