Kawasaki KLX300R Specs and Review Off-Road Bike 2022

Kawasaki KLX300R: After being obliterated by Yamaha and KTM for a few years and then the Kawasaki KLX300R has made a comeback thanks to its EFI-fed motor and ergonomics and design inspired by XK. 

Kawasaki KLX300R

Dirt bike enthusiasts regard KLX300R as the top two-wheelers available in its class.

Kawasaki KLX300R is a dual-sport bike that is liquid-cooled and 292cc first manufactured by Kawasaki from 1996 until 2007. 

The model for 2020 comes with additional features to boast about the DFI system, an electric starter, an MX-style middle section, and top-quality performance.

It is a highly regarded trail bike and its return is current. The riders love its linear engine, contemporary styling, and supple but comfortable suspension. 

It gained a reputable name for itself from the late 1990s through the early 2000s and is continuing to make waves with the present lineup. We’ll go into greater detail regarding the KLX300R Kawasaki.

About the Kawasaki KLX300R

KLX300R KLX300R is Kawasaki’s most powerful trail bike with high performance that aims to make the distinction between the recreational bike and the full-on competition bike. 

As the KLX line-up top model, it provides excellent control and a powerful engine in a compact, easy off-road bike. 

The dirt bike comes with an ecological Keihin power mill as well as a motocross-style frame for excellent suspension and ergonomics that are comfortable for long straightaways as well as technical trails. 

It also comes with an LED taillight and headlight as well as an odometer, handguards on the side and a USFS-approved spark arrestor, and a huge fuel tank that has a reserve petcock and chain adjusters that resemble snails to make it easy to remove the rear wheel and O-ring chain adjusters.

Kawasaki KLX300R Specs and Review

Overall the KLX300R was able to outperform its predecessor of 250cc. It also showed solutions to some of the predecessor’s problems. 

The rugged construction ensures the bike’s greater reliability and capability to withstand the toughest trail conditions. 

High ground clearance increases rider confidence and allows riders to get through technical terrain with ease. It’s not a model constructed from scratch. If you examine it closely, you can see it borrows many elements of Kawasaki’s KDX design. 

A few of these features include the steel perimeter frame with high-tensile, Enduro styling, and four-valve cylinder heads for example. 

It was a success in its own niche own, but it was unable to do a great job expanding the lineup in comparison to its 400 and 350-class competitors.

2020 Comeback

The KLX300R’s return is designed to bring the off-road bike back onto the map. The lime green bike comes with an electronic fuel injection system and an electronic start system that replaces the kick-start system of the past. 

Although these new features might seem a bit sloppy but they allow for riding and maintaining the KLX300R simple. The wheel travel is rolled out for both the front and rear suspensions.

Additionally, lighting has been eliminated. After its debut in Jacksonville, Oregon, riders, as well as media, we’re impressed with the overall design.

 Kawasaki KLX300R

Kawasaki KLX300R Top Speed

The maximum speed of the fuel-injected 2020 Kawasaki KLX300R is 75 miles per hour. 

The initial model is able to go up to 80 mph, whereas the 2006 KLX300R is rated at 85mph (with 33 horsepower and 8.500 RPM). With modifications, you might be able to achieve 100 mph or even higher. 

Even with modifications the bike will have a strong pull but will be easy to raise in 1st and 2nd gears. The DRZ400 will be able to eat dust when it comes to straight acceleration. 

It should be comparable (if not superior to) in comparison to the KLX300R against the CRF250F.

Keep in mind that KLX300R was never intended specifically for racing. However, suppose you wish to turn this Enduro bike to be an equivalent speed monster. 

In this case, you could include a power commander (check whether it’s the model is compatible with a ’20 model) and also change the exhaust.

You can also seek out assistance from a professional to set your suspension, buy more lightweight wheels and brakes, or a custom motor.

Trail Bike Makeover

Many people view the KLX300R as something in between an e-bike and the full race bike. 

It’s not surprising, considering that the two-wheeler can feel a little overwhelmed when it’s first put on. Although this may not be a big significance for those who ride trails, however, those who are off-road are likely to find the bike’s lagging performance quite irritating. Here are some suggestions to fix the issue:

      • Vent your crankcase in a proper manner It is possible to do this by removing the hose from the original and replacing it with a higher-performance one.
      • Clean the airbox lid and any other obstructions to intake – This will assist in introducing air into the machine.
      • Re-jet your carburetor. Either purchase a jet kit create one yourself. You can choose 1/16, or 160 jet size primary jet and then switch the jet pilot to 45.
      • Purchase a Stroker idler and shift kit fix.
      • Install a pumper carb such as one with a diameter of 33 millimeters Mikuni and an oversized head pipe and stiffer springs for the front and rear.

By making these small changes The efficiency of the KLX300R will be surprisingly great. 

It can also enhance the riding experience, but it will not solve the complete hesitation issue. In general, you’ll shift an adjustment on your carb in order to enhance the fuel mixture and eliminate any hesitation on the throttle. 

It is not possible to do this using an older model, such as a KLX300R or earlier, since that needle of the emission-compliant Keihin carb is not able to adjust.

KLX300R Reviews


Kawasaki enthusiasts aren’t convinced by the eco-friendly carburetor of the bike. A slight turn of the throttle at idle can cause a lot of anxiety because of the slow-building of the vacuum. 

While this is what has resulted in this KLX300R blue CARB badge, the fact is that it will not assist the rider in any way off-road. In the event of a crash, hesitation during jumps could result in serious issues.

Idler Gear

Another problem for Team Green is the idler gear. It’s weaker than it ought to be, however, it can be improved by installing the help of a Stroker kit. 

The ardent fans are confused because the Stroker kit creates the bike’s shifter to appear like XK models. XK models. If that’s the scenario, Kawasaki should not have changed its design in the beginning. 

Local and racing outfitters have informed Kawasaki of this issue for years. To people’s dismay, the maker continued to launch bikes that had this weakness. This is a great opportunity for dealers of parts, but it’s a cause for concern.

Accidental Shifting

For 2020s KLX300R The distance between the lever and footpegs can create accidental downshifts or upshifts. 

It is common for accidental shifting to occur at the worst timing for the riders. This is why it’s necessary to purchase an aftermarket replacement of a new lever for gear shifting. Also, there is a lack of bicycle accessories, such as handguards with OE fittings.

The Look

The shape-wise The 2020 KLX300R is more appealing, however, the earlier models had better branding and finish. 

While some people like the green/black/gold throwback design on the new model, however, others prefer the more retro style of the 1996 and 2007 models. Kawasaki taking the lighting off the KLX300R was also a source of frustration for certain consumers. 

A lot of people were not willing to pay an additional $300-$500 to get lights that ought to be standard for making the KLX300R street legal. Some users find the exhausts are too loud for their taste even after fitting the bikes with silencer caps. 

Some enthusiasts believe that suspension may improve. The suspension isn’t equipped with suspension rebound damping like its predecessors.


Another KLX300R disadvantage is that it’s not ADR-compliant. The restrictions imposed on manufacturers may be absurd. 

If Kawasaki had to comply with all the rules (again) this will result in no one purchasing the bike. The majority of the U.S. understands the same. 

Although it’s got the green CARB sticker, however, it isn’t intended to be registered.

Great Value

Apart from these minor issues, The KLX300R is an excellent value and good performance. 

The majority of them compete in the Texas cross-country series (four-stroke professional class). They can achieve the top 10 times with YZ426s or KTM 520s with just bolt-on KLX300R components. 

They are simple to ride and are able to perform even in tough sections. Pre-loved KLX300Rs are also available for sale at a reasonable price.

Conclusion – Kawasaki KLX300R Review

The Kawasaki KLX300R has enjoyed an impressive history of being an extremely stable platform. The fact that it is back has confirmed this even more.
