Kawasaki 2021 KFX50 for Sale at Ultimate Kawasaki Ipswich in West Ipswich, QLD | Specifications and Review Information

Start Them Right With a Kawasaki Fun ATV

Start them on the right track with the fun of the Kawasaki KFX50.

Designed specifically with little bodies in mind, the KFX50 boasts a range of user-friendly features such as a built-in throttle limiter, automatic transmission and low seat height.

For extra parental control and safety, the Kawasaki KX50 ATV is fitted with a second rear-mounted, lanyard kill switch. This enables the parent to follow behind and shut the engine down by pulling on the lanyard.

The KFX50 is the kid sized ATV that will bring them years of fun and provide a safe learn-to-ride environment.


A throttle limiting screw located on the top of the throttle housing allows parents to limit the throttle opening to help new riders gain experience at slower speeds. A removable collar installed in the CVT limits travel of the driven converter, producing a lower overall drive ratio to reduce speed. Keyed ignition switch prevents starting without a key. Ignition cut-off tether allows an adult to immediately stop engine operation by pulling on the tether line. Read and understand the Owner Manual recommendation on the minimum age of operators of 6+ years. Always operated under direct adult supervision. Always wear an approved helmet and protective riding apparel.



Simple operation for young riders. The CVT eliminates gear shifting to simplify operation. The young rider can simply push the throttle and go. The centrifugal clutch on the driven converter allows engine braking under certain conditions for added control and slowing power when travelling down hills.


Easy push button start with the key switched on. The interlock feature only allows the engine to be cranked when the parking brake is engaged. The sealed battery requires minimal maintenance. The KFX50 has a back up kick starter system if the battery does go flat.


Full floorboards provide sure footing and help to keep the young rider's feet and legs away from the wheels.


Single A-arm front suspension with twin shock absorbers. Single Shock rear suspension system.


Responsive braking performance from dual front drums and single rear disc.


The control levers on the KFX50 are sized to suit young riders and placed within reach of the ATV rider.
