Front LED accents lights and LED taillight add to the already race-inspired bodywork. The grill shape contributes to the sharp design of the front, while tall front fenders convey a strong sporty off-road performance look.
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.
The KFX90 ATV lets riders ages 10 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.
Independent A-arms in the front and swingarm rear suspension soak up bumps for a smooth ride and contribute to sporty handling.
