Kawasaki KLX140 Review – Everything You Need To Know About It

Looking for the best beginner bike? Maybe you’re considering which bike would be best for your wife or a girl in your life like I was for my wife. This is a comprehensive guide and review on Kawasaki’s KLX140 trail bike. I want to help you decide if this is the best dirt bike for you or not.

What is the KLX140?

The KLX140 is a 144cc air-cooled 4 stroke trail bike with a 5-speed manual clutch and transmission. It has 4 different wheel sizes, all aimed at beginner riders of different sizes. It is still carbureted and not fuel injected. But it does have electric start, removing some of the frustrations if you’re a new rider learning to ride.

A clean stock 2008 Kawasaki KLX140 is a great beginner bike to learn to ride on.

The KLX140L is the closest rival to Honda’s CRF150F that you just read about. It has mid-size wheels and a simple, reliable 144cc air-cooled 4-stroke engine.

Is the KLX140 a good bike?

The KLX140 is one of my favorite dirt bikes for beginners. It’s great if you’re just starting out and want a quality bike that’s super easy to ride. The suspension is nice and plus, it starts easy, and it handles very well. It may not have EFI, but I recommend using non-oxygenated gas and you shouldn’t have carb problems.

Lightest, Most Compact Package

The KLX 140L has a one inch lower seat height, and almost 2 inch short wheelbase than the CRF150F. Coming in at 209lbs wet and ready to ride, the 140L is the lightest bike in it’s class. It’s an excellent dirt bike for teens, females, riders 5’6″ and shorter, or if you just want to start out on a nice, compact set of wheels.

Simple, No-Nonsense, Reliable Machine

Much like most of the other bikes in this guide to buying the best beginner dirt bike, the KLX140L is a very basic and homely platform. The air-cooled engine is durable, the suspension is simple, yet plush and friendly to new riders.

KLX140 vs TTR125

The KLX140 definitely has more power, but does that alone make it better vs the TTR125? It’s just as reliable and I like the ergonomics and handling a little more. The only problem is they’re harder to find used and usually cost several hundred dollars more.

KLX140L Final Impressions?

Lowest seat height? Check. Electric start? Check. Cheap to buy? Check. If you’re looking for the best mid-size beginner dirt bike, the KLX140L is as good as it gets.

Kawasaki KLX140G

Wait, didn’t I just read about the KLX140? Yep, but the KLX140G is a newer version that Kawasaki updated for riders that want a full-size dirt bike, but still like everything else about the little 140.

The 140G has full-size wheels (21/18″), so the seat height and wheelbase are taller and longer. It only weighs 9lbs more, so it’s still lightweight compared to the rest of the pack.


KLX140G Final Impressions?

The KLX140G has the lowest seat height and is the lightest full-size 4-stroke dirt bike on this list. It may not have a lot of power, but it will be the easiest to ride.

With an MSRP of well under $4,000, this is a very affordable beginner bike. They’ve already been around for a few years, so waiting to find a used one can save you even more cash that could be spent on proper riding gear and gas.


  • Very low seat height (33.9″)
  • Only 218lbs wet
  • Full-size wheels
  • Electric start
  • Low CoG
  • Reliable
  • Cheap for a full-size dirt bike


  • Low power output
  • Similar cockpit size as the KLX140L
  • No back-up kick-start
  • It’s green?
