Following the worldwide critical and commercial success of the Speed 400 and Scrambler 400 X, Triumph Motorcycles and Bajaj Auto are preparing to expand the TR-series single-cylinder platform with the Triumph Thruxton 400. Embracing the racing lineage of the legendary Thruxton 1200 RS, this sub-500cc cafe racer incorporates low-mounted clip-on handlebars, rearset footpegs, a Monza-style aerodynamic bubble cowl, and a sculpted 13.5-liter tank.
1. TR-Series 398.15cc DOHC Engine Architecture
Under the neo-retro bodywork lies the proven 398.15cc liquid-cooled 4-valve DOHC single-cylinder engine, featuring an oversquare 89.0mm bore and 64.0mm stroke with a 12.0:1 compression ratio. It delivers 40.0 PS of power at 8,000 RPM and 37.5 Nm of torque at 6,500 RPM. The valvetrain uses Diamond-Like Carbon (DLC) coated finger followers to minimize reciprocating friction, while a weighted crankshaft balance shaft cancels primary single-cylinder vibration. Power reaches the rear wheel via a 6-speed constant mesh gearbox with a torque-assist slipper clutch.

2. Cafe Racer Ergonomics & Chassis Dynamics
The Thruxton 400's rider triangle is purpose-built for aggressive canyon carving and track-day handling. Forged aluminum clip-on handlebars are clamped directly beneath the top triple tree, dropping the rider's grip height by 45mm compared to the Speed 400. CNC-machined rearset footpegs are moved 40mm rearward and 15mm upward, facilitating lean angles up to 46° without peg contact. The sculpted fuel tank features rubber knee pads, leading to a ribbed saddle fitted with a removable color-matched Monza tail cowl.
3. Showa Big Piston USD Suspension & ByBre Radial Brakes
Front suspension duties are handled by 43mm Showa Big Piston inverted (USD) forks offering 140mm of travel, calibrated with progressive spring rates to support aggressive front-end trail braking. The rear features a gas-charged Showa monoshock with an external piggyback reservoir (130mm travel) and 5-step preload adjustment. Stopping power is anchored by a 300mm floating stainless steel front disc clamped by a ByBre radial-mount 4-piston caliper with sintered metallic pads, backed by switchable Bosch dual-channel ABS and Triumph Traction Control (TTC).
4. Competitor Positioning & Pricing Analysis
Expected to be priced between ₹ 2.45 Lakh and ₹ 2.58 Lakh Ex-Showroom, the Thruxton 400 slots directly between the Speed 400 (₹ 2.34L) and Scrambler 400 X (₹ 2.64L).
