Triumph Thruxton 400 vs Speed 400 Spec Comparison: What's Different?

Triumph has just launched the Thruxton 400 in India, adding a third model to its 400cc lineup alongside the Speed 400 and Scrambler 400X. Like its siblings, this one is built locally by Bajaj Auto. Though it shares the same 398cc engine and platform as the Speed 400, the Thruxton takes a different path. It’s aimed at riders who want classic styling with a more focused riding posture.

Triumph Thruxton 400 vs Speed 400: Design

The Speed 400 showcases a modern streetfighter look with sharp, muscular bodywork, featuring a muscular fuel tank and a minimalist tail section. Its styling is contemporary and aggressive, appealing to riders who prefer a fresh, bold appearance.

In contrast, the Thruxton 400 adopts classic cafe racer design cues, with a semi-faired body, a distinctive flyscreen, and a round headlamp nested within a sculpted front cowl. Additional vintage-inspired touches include clip-on handlebars, bar-end mirrors, and a single seat topped with a rear cowl. The Thruxton’s blacked-out front forks and transparent brake fluid reservoir add subtle premium touches, highlighting its retro-modern appeal.

Triumph Thruxton 400 vs Speed 400: Ergonomics

The Speed 400 offers an upright, relaxed riding posture, achieved through wider and higher handlebars that promote comfort during city rides and daily use. It has a ground clearance of 164mm and a longer wheelbase of 1386mm, contributing to stable handling.

Meanwhile, the Thruxton 400 shifts towards a sportier and more committed ergonomics setup typical of cafe racers. Its clip-on handlebars are 40mm narrower and 246mm lower, while the rear-set footpegs are positioned further back and higher, encouraging a forward-leaning stance. With a slightly lower ground clearance of 158mm and a 1376mm wheelbase, the Thruxton is designed for nimble, responsive cornering and more aggressive riding.

Both motorcycles share the same 398cc single-cylinder TR Series engine, but with distinct tuning differences. The Speed 400 produces 39bhp and 37.5Nm of torque, with a redline set at 9,200rpm, providing smooth and manageable power suited for a broad range of riders.

The Thruxton 400’s engine features revised cam timing and a rear sprocket with two fewer teeth, elevating the redline to 10,200rpm and boosting peak power to 41.43bhp. Although peak torque remains at 37.5Nm, it arrives at a higher 7,500 rpm, resulting in more spirited, top-end performance.
