Four-wheel fun starts with KFX. Give kids ages six and older the ability to confidently tackle the dirt. KFX50 ATVs are ideal for young riders to start their adventure, featuring 50 cc of power and smooth performance that can help give riders experience in a controlled manner.

Perfect For Young Riders (ages 6+)

The new KFX50 ATV for ages six and older is the starting place for many first-time ATV riders.The 50 cc four-stroke engine starts with the push of a button and features an engine stop lanyard, while the automatic transmission helps deliver smooth power, beginner-friendly performance and rock-solid reliability.

Safety First

Parental controls include a keyed ignition to help address unsupervised use as well as speed controls with an adjustable throttle limiter and automatic Continuously Variable Transmission (CVT) collar that allow the speed and performance to be adjusted to match rider experience.New full coverage floorboards with slip-resistant footing contribute to increased grip and help 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.

Easy To Handle

Independent A-arm front suspension and swingarm rear suspension soak up bumps for a smooth ride and sporty handling, packing a lot of fun into a small package.

Sporty Design

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. Additionally, a taller design of the front fenders conveys a strong sporty off-road performance look.
