Are You Ready to Dominate the Dirt?TRX400X is a tough, no-nonsense sport ATV for riders who are tackling demanding trails, and who want the performance and reliability that has made Honda famous. Built around a powerful SOHC, 397 cc, air-cooled, dry-sump RFVC engine the chassis offers Baja-ready Pro-Link® suspension with long travel and triple disc brakes. Reverse? It's standard equipment too. And so is the refinement and comfort that let you spend all day in the saddle.
