Triumph Thruxton 400 vs Triumph Speed 400 Spec Comparison: What’s Different

The Triumph Thruxton 400 has been launched in India at Rs 2.74 lakh (ex-showroom), expanding the brand’s 400cc range that already includes the Speed 400 priced at Rs 2.50 lakh. While both models share the same engine platform, they differ in styling, riding dynamics, performance characteristics and overall setup. Here's a detailed specification-based comparison.

The Thruxton 400 follows a distinct cafe racer approach, Its riding position leans toward a sportier, committed stance with clip-on handlebars, a sculpted fuel tank and a colour matched rear seat cowl. On the other hand, the Triumph Speed 400 has a more upright handlebar setup and a cleaner overall profile, making the Speed 400 better suited for daily use and longer commutes.

Both motorcycles are powered by the same 398cc, liquid-cooled, single-cylinder engine with a 4-valve DOHC setup paired with a 6-speed gearbox, a wet multi-plate assist and slipper clutch and use an X-ring chain for final drive. However, the power delivery is different: The Thruxton 400 produces a peak output of 41.4 bhp at 9,000 rpm, and the Speed 400 delivers 39.5 bhp at 8,000 rpm. Torque figures remains the same at 37.5 Nm, but the Thruxton’s torque peaks at 7,500 rpm compared to 6,500 rpm on the Speed 400.

The two motorcycles share the same hybrid spine/perimeter frame with a bolt-on steel subframe. Suspension is also largely similar, with both models featuring 43mm upside-down Big Piston forks at the front offering 140mm travel. The difference lies in the rear suspension travel: the Thruxton 400 has a slightly longer 130mm travel compared to 120mm on the Speed 400. Braking is identical across both models, with a single 300mm front disc paired with a four-piston radial caliper and a 230mm rear disc, both supported by dual-channel ABS.

Dimensionally, the Speed 400 is marginally longer in wheelbase at 1386 mm compared to the Thruxton’s 1371 mm. The Thruxton also has a slightly higher seat height at 805 mm, while the Speed 400 sits at 803 mm.
