About Kawasaki KLX 250

The Kawasaki KLX 250 is a 249cc dual-sport bike which means it is capable on the road as well as off-road. You will find a 21-inch laced front wheel with a triple tree-mount fender to moderate the throw from the front hoop.

The KLX 250 started its journey in 2009, and it progressed slowly, releasing models every year since 2014. But the production certainly halted after that. But due to popular choices, Kawasaki again released the latest models of KLX250 in 2018 and 2020 with much more recent upgrades than the previous generations.

Kawasaki KLX 250 Specs & Features:

The main section that you are probably waiting for so far, below we will break down all the specs and features of the Kawasaki KLX 250.


Power is delivered from a 249cc, 4 stroke DOHC engine. This is a fuel-injected single-cylinder 4-valve liquid-cooled engine. The compression ratio is 11.0:1 and comes with a fuel capacity of 7.7 liters. It comes with a bore of 72.0 mm along with a stroke of 61.2 mm.


The drivetrain includes a manual 6-speed transmission with 4.2 inches of rake/trail. While the ratio between the first and sixth gear is 3.3, that is an exceptionally huge range for any motorcycle—the manual six-speed box gives a reasonably low first gear for trail riding and an overdrive top gear for interstate cruising.


KlX 250 has a digital DC-CDI ignition system that enables easy starts and reliability under harsh conditions, regardless of RPM variation.


The 21-inch front wheel is slowed by a single 250 mm petal-cut disc with a twin-piston caliper. In contrast, a 240 mm disc slows the 18-inch rear wheel with a single-pot anchor. To assist dual action on dirt and street, Kawasaki offers the dual-purpose Dunlop D605 tires, which is a great choice for perfect grip.


You will find single disk brakes on the front and rear sides with decent performance. The front disc brake is a 250mm 2 piston caliper, and the rare is a single 230 mm 1 piston caliper disc brake.


The suspension travel raises the seat height to a comfortable 35 inches, with telescopic front suspension and Uni-Track Swingarm rear suspension. The KLX 250 can handle the huge boulders and sand whoops of the desert, as well as logs and other trail hazards, thanks to 11 inches of wheel travel on both ends. Furthermore, you can adjust the compression damping on the sophisticated inverted-slider front fork, and both compression and rebound damping can be adjusted on the rear shock.


Overall Length of the bike is 86.6 inches, with a width of 32.3 inches and a height of 47.4 inches. The wheelbase has a height of 56.3 inches and a height of 35.0 inches. Wet weight is 304 lbs and has a turning radius of 2m.


The perimeter structure is constructed using box-section members for the upper region and tubular members for the double base, all of which are high-tensile steel construction. The bones have an aluminum D-section swingarm, which is light yet durable and helps to reduce rear-wheel weight.

Kawasaki KLX 250 Top Speed

Kawasaki KLX 250 has a top speed of 85 mph. Kawasaki dirt bikes are known for their high speed, and the KLX is no exception. This is a beast when it comes to dirt bikes at the 250cc limit.

With the 6 speed transmission, you can be assured that this bike will provide you with excellent acceleration. When racing on roads, you won’t notice any wheel flex on the trail. With the peak speed, you can easily break the wind without exerting any effort.

Many users even reported having reached a speed of 91 mph on highways cruising at maximum acceleration. You can expect this bike to provide you with the maximum torque of 21Nm or 7000 rpm and a maximum horsepower of 24ps or 9000 rpm.

How to Increase the Kawasaki KLX 250 Top Speed?

Air resistance and horsepower will restrict your peak speed. Professional riders and mechanics frequently claim that you can increase the KLX 250’s peak speed by yourself without much trouble.

Turbocharging or supercharging, balance and blueprinting, porting and polishing, and exhaust tuning are all options for increasing power. So read below to know about effective ways to increase the top speed of your KLX 250.

Air Filter

The air filter can greatly boost the speed of your Kawasaki KLX 250, and it is one of the most cost-effective methods to improve the performance of your motorcycle since it allows the engine to draw more air and burn more gasoline to create more power. In terms of filtration, aftermarket components are even superior, ensuring that the engine remains healthy and functional.

Modify Compression

Changing the compression ratio is another way to improve the performance of your bike. You’ll need to replace the piston in your 4-stroke KLX 250 with one that has a more prominent conical shape if you want to adjust the compression.

Better compression, in essence, improves the force of your acceleration, but it does so at a cost. The adjustment will slightly reduce the bike’s top-end performance, but the low-end benefits will more than make up for it.

Play with the gears

A larger rear sprocket or a smaller front sprocket will increase acceleration, while the contrary will focus the motorbike more on maximum speed. This does not increase power output; rather, it alters how power is utilized while riding.

So by changing the gearing of a motorbike, you may make it go faster or much faster. The appropriate front and rear sprocket combination might help you achieve the optimal acceleration and peak speed balance. The amount of teeth you have makes a huge difference.

Change the Clutch

Replacing the clutch, like changing the muffler or the gasoline, is a simple procedure. Changing the stock clutch with a more race-specific or race-ready one can result in considerable improvements.

Those increases, nevertheless, will not be in the form of horsepower. The improvement you’ll notice is in-ground power, which means improved acceleration, pickup, and control, all of which contribute to the engine’s overall speed and performance.

Kawasaki KLX 250 – Pros and Cons:

As with all products, you will have some pros and cons. The same applies to the Kawasaki KLX 250. Below, we will list all the pros and cons of this fantastic bike.


  • Easy Controlling: Dirt bikes or sport bikes are often not easy to control for beginner bikers. However, this scenario is different for KLX 250 users. This bike is designed to be very lightweight and has a narrow fuel tank design which makes this one hell of a bike to control both for beginners and professional Motocross riders.

The KLX is a gentle bike that does not impose undue strain on its user. It doesn’t need you to be an athlete or even to put up a lot of effort. It reliably and comfortably transports you anywhere in dirt and road.

  • Stock Luggage Joints: Two luggage joints are on either side of the rear subframe and another on the bottom subframe. When you want to strap on some camping gear, this makes things a whole lot easier. There’s also a helmet lock, which comes in useful when you need to run to the store or get a drink.


  • Small Fuel Tank: As bike enthusiasts, we find the fuel tank to be pretty small, and it can be quite unpleasant during long rides. The fuel range is simply insufficient. The bike is in need of a gallon more, especially given the type of bike it really.
  • Small Footpegs:  Even though the footpegs are made of high-quality steel, they are not comfortable for street riding since they are too narrow. However, off the beaten path, do keep in mind the KLX is designed to be a dual sportbike. So, it is obvious to expect a similar type of performance from both on and off-road.
