Kawasaki KX100 Review

Designed to put its riders on the lead, KX100 features significantly improved performance, ergonomics, comfort, and ease of operations. This way, it’ll be easy for the young rider to want and enjoy more practice sessions. What’s more?

Kawasaki KX100 Top Speed: 65mph (105 KM)

Comfort and Convenience

The KX100 starts at the first kick, and you don’t even have to sit on it to kickstart. It’s easy to reach for the young rider and doesn’t require much effort. Better still, it starts immediately with just one trial, and off you go.

Even though it’s a featherweight, the KX100 felt reasonably manageable, giving your child the confidence to keep exploring. The throttle is pretty easy to engage.


KX100 operates on a KIPS system with an exhaust porting, particularly for increasing power from the bottom. Better still, the KIPS has a breather that overruns performance to improve the high rpm.

Expect a noisy experience from the potent engine as it intensifies with high speed.

Ergo-Fit System

This user interface system allows the rider to find a perfect position in several areas like the seat, footpegs, and handlebar. Ergo-fit is highly adjustable on specific parts to meet the needs of different users-short or tall.

 Better still, it allows the rider to reach the ground properly to ensure a comfortable positioning.

Price and Competition

The US price for KX100 is $4,649 for the Lime green. The KX100 doesn’t have direct competition with the unique two-stroke displacement level.

But there’s room for indirect competition from Husqvarna TC 85, Honda CRF150R, and 2022 KTM 125 SX.
