Shaping the next generation of ATV riders
Riders 12 years and older appreciate quality products designed to fit their growing physiques. The wide stance, large tires, friendly performance and big-ATV styling of the KFX®90 ATV ensure that it appeals to this crowd. Full floorboards compliment the KFX90s stable and confidence-inspiring handling traits, making it a smart choice for parents who value quality and performance.
At the core of the KFX90 is a reliable and environmentally friendly four-stroke, air-cooled 89cc engine providing healthy mid-range performance with an easy-to-use power delivery. Its approved spark arrestor means young riders can tag along on trail rides. The rider can focus more attention on line selection and developing his or her riding skills, thanks to the KFX90s continuously variable automatic transmission (CVT) which eliminates the need to concentrate on a clutch or shift lever.
Parents are also sure to appreciate the added security offered by the KFX90s keyed ignition switch which prevents use without the key. Once they hand over the key, parents can still exercise control over the KFX90s available performance, via the throttle limiting screw and a CVT transmission speed limiter. These allow the ATVs maximum speed to be preset to match a riders ability.
The KFX90 is also equipped with premium features like electric starting, a single-shock rear suspension, independent A-arm front suspension, and a single rear disc, supplemented by dual front drum brakes.
