For riders 12 years and older, the KFX90 is the perfect ATV choice. It offers beginner friendly performance with big-bike styling. Power is generated from an easy to use and environmentally friendly four-stroke air-cooled powerplant that provides great mid-range power delivery.

Highlighted by its sport ATV design, wide stance, larger tires, and full floorboards, the KFX90 offers handling traits that are stable and confidence-inspiring for the youth rider. The KFX90 also has electric starting, single-shock swingarm rear suspension, A-arm front suspension, dual front drum and single rear disc brakes, much like those found on the larger KFX models.

Parents are sure to appreciate the added control offered by the KFX90s keyed ignition switch which prevents use without the proper key. Once they hand over the key, parents can maintain control over the KFX90s use via the throttle limiting screw and a CVT transmission speed limiter. These allow the maximum power to be preset to match the young riders ATV ability and let the young rider's confidence and skill levels to increase in controlled increments.
