The KFX450R uses a powerplant based on Kawasaki’s highly acclaimed KX™450F motocross engine. An efficient and highly-responsive 32-bit digital fuel injection (DFI) system automatically compensates for temperature or altitude. DFI also enhances the engine’s ability to generate torque in the low and medium rpm ranges for outstanding holeshot acceleration. This ATV’s ability to find traction is superb, and its four-stroke power delivery translates into hooked-up wheels for improved handling and higher corner speeds.
Other race-ready features include a lightweight titanium exhaust header pipe and a durable forged piston. The fast and reliable KFX450R was also the first competition-oriented ATV to include a reverse gear. Previously unheard of in racing, the KFX450R’s lightweight reverse system lets riders quickly extricate themselves from first turn chaos, dead-end trails or any other on-track incident.
