Vehicle Information
Honda TRX400X ATV (2009-2014)
The Honda TRX400X, produced from 2009 to 2014, is a sport ATV renowned for its robustness and reliability. It was powered by a 397cc, air-cooled, dry-sump, single-cylinder, four-stroke engine featuring a Radial Four-Valve Combustion Chamber (RFVC) and a Single Overhead Camshaft (SOHC) configuration. This engine, drawing from the "bulletproof XR400R," was fed by a 38mm carburetor and provided ample power and torque for trail riding. Throughout its production from 2009 to 2014, the TRX400X maintained a single trim level and underwent no significant engine or platform changes. Updates were limited to minor aesthetic revisions, such as new colors or updated graphics, ensuring a consistent and proven design until its discontinuation in 2014. FAQ:
