The TRX®400EX has always been an ATV that really delivers when it comes to power and handling. But for 2008, its totally redesigned bodywork matches its legendary performance and provides superior splash protection. The new seat is wider in the back and narrower in the front to improve ergonomics. And to make it easier to ride, it offers a lighter clutch-pull and improved suspension settings. The TRX is still powered by the same bulletproof 397cc engine, mounted in a rugged steel frame, and features a one-piece cast-aluminum swing-arm, radial tires and triple disc brakes. All that and more helps give you the performance you need to take on your favorite ride.
