Get the kids outdoors and ready to ride on the KFX90 ATV with proportionate power and size that’s perfect for riders ages 12 and older. The KFX90 lets kids take on tougher tracks and bigger adventures with an 89cc engine, while parental controls allow you to regulate their progress.

Reliable & Accessible

89cc four-stroke engine produces smooth and predictable power, making it ideal for new riders ages 12 and older. An adjustable throttle limiter and Continuously Variable Transmission (CVT) collar allow speed and performance to be adapted to rider experience.

An Easy Start
