2022 KLX140


The 2022 KLX140 is one of the best beginner bikes (or pit bikes) on the market.

Whether you’re looking for a good bike for your child, or you’re an adult looking for a pit bike that’s a bit bigger than the popular 110s, the 2022 Kawasaki KLX140 can be a great option.

I rode one of these twice recently. Once on a motocross track and once in the woods. Both times were a blast!

In this article, you will find a full review and guide to help you decide if the KLX140 is for you.

2022 Kawasaki KLX140 

The 2022 KLX140 has a single-cylinder 144cc air-cooled four-stroke engine. The new KLX140 models offer a big bike feel in a mini package.

Compared to the 2017 KLX140G, the new 2022 KLX140 model offers a much friendlier ride to new riders.

The appearance of the 2022 KLX140 is awesome and stands out from the traditional trail bike look. Kawasaki found inspiration in KX motocross bikes, and people love that decision. 

The KLX140 also has a 5-speed manual transmission (meaning it has a clutch). It has an electric star and is not fuel injected (it’s carbureted). (We’re hoping Kawasaki adds fuel injection to its 110’s and 140’s soon, following its competitor Honda’s CRF110). 

The KLX140, KLX140L, and KLX140G are virtually the same bike but have different wheels, tires, and seat heights.

2022 KLX140 Updates 

What was previously known as KLX 140, KLX140G, and KLX140L are now KLX140R, KLX140RL, and KLX140RF. With the new updates and names, Kawasaki may confuse many customers. Therefore, we are here to help you and explain what the fuss is all about. 


The KLX140R has no big changes despite the additional letter and smaller wheels. This model is the smallest and shortest of the 140cc family and offers a clutch from Kawasaki. The KLX140R has a 30.7” seat height and 14″ and 17” wheels and tires. This edition is perfect if you are about 4′ 8″ to 5′ tall.

In this model, the L stands for larger wheels, and the entire frame of the bike is slightly bigger. Although the bike is taller, its bigger tires roll more easily on the trail, and obstacles can be avoided much more easily. 

The KLX140RL seat height is 31.5”, and the tires and wheels are 16″ and 19”. This model is a great choice if you are over 5 feet tall.

This bike has the biggest wheels, and it is full-size. What was previously called the KLX140G now the model has an additional “F” that stands for full-size wheels. 

The bike is eligible for adults with a late start on their dirt bike journey because it doesn’t have too much power and rides easily. The KLX140RF model has 18″ and 21″ wheels.

Even though the bike does not have the stability of a big adult-size dirt bike because of its shorter wheelbase and overall geometry, it is still a great choice for beginners.

The KLX140RF has a seat height of 33.9” seat height and fits best for 5′ 4″ to 5′ 8″ tall riders.

Horsepower and reliability

The 2022 KLX140 at the rear wheel makes about 9 HP.

The number 9 HP describes the peak power at a specific RPM. It makes 9 HP at about 8,000 RPM.

As for reliability, the KLX140 is one of the best in the industry. If you enjoy the trails with a dirt bike that does not require frequent maintenance, the 2022 KLX140 is a great choice.

All you have to do is check the oil and air filter before every ride, fill the gas, and run a wrench over all the nuts and bolts, then you’re ready to ride.

2022 KLX140 Price 

The three different models of Kawasaki 140 come at different prices. The KLX140R is $3,499, the KLX140RL is $3,749, and the KLX140RF is $4,049. 

If you like to purchase one of the bikes in a used condition, the price depends on the local market. Based on multiple factors, you can find a second-hand KLX140 anywhere from $1,500 to $3,000. 

If you’re into the 2022 KLX140, you’re probably a Kawasaki fan, but a comparison that is often made is the TTR125 vs KLX140. Check it out.
