2011 KFX 90

The KFX®90 ATV allows young riders to answer the call to adventure. Its fully automatic transmission, full suspension and big ATV styling make it a great machine to introduce riders 12 and over to the world of four-wheeling. Parents will appreciate the KFX90’s smooth, stable handling and the protection offered by full floorboards.

An environmentally friendly four-stroke 89cc engine powers the KFX90, providing healthy mid-range performance with a compliant power delivery. The easy-to-use continuously variable automatic transmission eliminates the need for a shift lever, so riders can pay more attention to improving their riding skills than on shifting. The dual front shocks and swingarm rear suspension help cushion a young rider from bumps, making the ride even more enjoyable.

Parents will value the added security offered by the KFX90’s keyed ignition switch, which prevents use without the key. Once they hand over the key, parents can still exercise control over the KFX90’s available performance, via the throttle limiting screw and a CVT transmission speed limiter. These allow the ATV’s maximum speed to be preset to match a rider’s 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.

Authentic Kawasaki Accessories are available through Kawasaki dealers.

As with all off-highway vehicle recreation, Kawasaki encourages ATV riders to ride responsibly and to respect the environment. Kawasaki will pay first-time buyers of a new Kawasaki ATV $100 for completing an ATV rider safety course conducted by the ATV Safety Institute (ASI). Interested consumers can call ASI toll-free at 800-887-2887.
