Four-wheel fun starts with KFX. Get the kids outdoors and ready to ride on the KFX90 ATV line with proportionate power and size for riders ages 12 and older. KFX90 ATVs let kids take on more challenging tracks and bigger adventures with a 90 cc engine and sporty suspension.

Reliable & Accessible

The new KFX90 ATV lets riders ages 12 and older take on tougher tracks. A 90 cc four-stroke engine equipped with an electric start for simple and reliable starting produces smooth and predictable power.Parental controls include a keyed ignition to help address unsupervised use, as well as speed controls with a throttle-limiting screw to restrict throttle movement, and a collar in the automatic Continuously Variable Transmission (CVT) that can be removed to increase speed as the rider gains experience, allowing the KFX90 to grow with the rider.

Get A Grip

New full coverage floorboards with slip-resistant footing contribute to increased grip and helps young riders control their ATV when riding while in a standing position. Increased mud protection keeps the engine running at a cooler temperature and keeps dirt and debris from building up near the engine.

Smooth Out Your Ride

Independent A-arms in the front and swingarm rear suspension soak up bumps for a smooth ride and contribute to sporty handling.

Ride With Swagger

New white number plate-style design, front LED accents lights and LED taillight add to the already race-inspired Lime Green bodywork. The grill shape has also been updated, contributing to a sharper design, and a taller design of the front fenders conveys a strong sporty off-road performance look.
