Building on the success of Kawasaki’s highly acclaimed KX™450F motocross engine, the all-new, race-ready KFX®450R is the first sport class ATV to offer a light-weight, all-aluminum frame for optimal handling and superior rigidity needed on the track. Another first in this class is a competition-oriented reverse gear, perfect for getting out of those first-turn traffic jams or dead-ends on tight trails. The Keihin fuel-injection system maintains crisp engine response, regardless of altitude or outside temperatures. The racing-style chassis features a single box tube lower frame tube which allows maximum lower A-arm length. This highly advanced ATV racer comes with all of the performance and technology necessary to put you at the head of the pack, without the hassle of modifications. It’s also easy to work on, so riders can spend less time wrenching and more time riding.
