This One Was Born Ready.

Relentless. Tireless. Tenacious. There are plenty of things you can say about the Honda TRX400X, but to fully understand it, you have to experience it. That’s because underneath the race-style bodywork lies everything the warrior ATV rider needs, starting with the SOHC, 397cc, air-cooled, dry-sump RFVC (Radial Four-Valve Combustion Chamber) engine. Then there’s the triple-disc brakes. Baja-ready Pro-Link® suspension with long travel. Standard reverse and all the reliability you’d expect from a Honda. We’ve even given it all-new graphics for an even more aggressive look.

So if you’re looking for high-performance ATV that delivers the power, comfort and dependability you need to tackle any terrain all day long, look no further than the Honda TRX400X.

The Heart Of A Competitor: Within the TRX400X’s engine lies a Radical Four-Valve Combustion Chamber, ensuring an efficient flow of maximum torque and horsepower.

Look The Part: New graphics give this competition-hungry ATV an even more imposing look, while the suspension and rider ergonomics help you dominate all day long.

  • High-Performance 397cc Engine: Radial Four-Valve Combustion Chamber (RFVC), the same design that powered the bulletproof XR400R, ensures maximum combustion efficiency and horsepower. Camshaft timing developed specifically to meet ATV requirements for torque and useable horsepower.
  • Counterbalancer: Some other big singles beat you up with vibration and buzz, but not the TRX400X. A gear-driven counterbalancer minimizes engine vibration for smooth operation.
  • Snorkel-type Airbox: If you sometimes ride in less-than-ideal conditions, you’ll appreciate the TRX400X’s snorkel-type airbox. Designed to help your engine avoid contamination from water and dirt, you’ll keep going while your buddies are stuck.
  • Heavy-Duty Clutch: Not just a motorcycle clutch in an ATV engine, the TRX400X’s heavy-duty clutch has 2mm-thick plates that are specially designed to stand up to sport-ATV demands.
  • Electric Starter: Effortless electric starter makes getting the engine started easy. Even when the engine is cold or at high altitude, all you need to do is push a button.
  • Reverse: Easy to use reverse for unloading or getting out of tight spots.
  • Skidplate Protection: High-impact plastic skidplates protect engine cases, rear-brake disc and drive sprockets from the trials of the trails. It’s all part of Honda’s attention to detail and why your TRX400X is designed to be trouble-free.
  • Cast-Aluminum Swingarm: One-piece cast-aluminum swingarm is a specially designed piece that optimizes strength, rigidity and durability, but that is still light and which helps reduce unsprung weight.
  • Competition-Spec Suspension and Chassis: Pro-Link® rear suspension features a one-piece cast-aluminum swingarm and fully adjustable large-diameter aluminum-body piggyback Showa® shock delivering 9.1 inches of travel. Triple disc brakes feature superb stopping power and a weight-saving aluminum rear caliper stay.
  • Triple Disc Brakes: Featuring excellent stopping power and superior feel and feedback, these triple disc brakes (two front, one rear) also run cool. An aluminum rear caliper stay also helps shave weight.
