2023 Kawasaki KX250 Dirt Bike Review Specs

Off-road competition now uses the championship-proven technology of KX race machines. The 2023 Kawasaki KX250 Dirt Bike is built with harsh off-road conditions in mind, giving riders the edge they need to go further. Take the lead on the KX250X confidently, no matter how rough the terrain.

This cross-country motorbike, based on the highly developed 2023 Kawasaki KX250 Dirt Bike, has been specially designed for cross-country riding, with an improved engine, suspension, brakes, wheel size, gearing, enduro tires, side stands, and Skid plates included. This tuning has increased the 2023 Kawasaki KX250 Dirt Bike’s appeal to cross-country competitors.

2023 Kawasaki KX250 Dirt Bike

Kawasaki’s KX250X Cross-Country Racer, with a long history of off-road racing, retains the championship-winning performance and all the factory-style features of the KX250 motocross racer, such as engine tuning for better performance throughout the powerband. Dates.

However, it does include X-specific suspension settings, 21/18-inch wheels with enduro-type tires, and valuable standard features like side stands and a skid plate to give it an advantage in off-road racing.

DFI Couplers

The KX250’s digital fuel injection system includes a coupler package that has established industry-standard ECU tuning, contributing to the engine’s race-winning characteristics. Three separate couplers are included as standard equipment with every KX250 motorcycle, making it easy for riders to select pre-programmed fuel injection and an all-new ignition mapping to suit their riding preferences or track conditions.

The DFI® engine selects maps with four-pin couplers for standard, rigid, or soft terrain settings. A priority coupler cap must be attached to change the engine map. The KX FI Calibration Kit (Handheld), available as a Kawasaki Genuine Accessory, gives riders access to a fully programmable ECU to fine-tune their settings.

Factory race teams use a handheld gadget that lets riders create unique maps for accurate fuel and ignition setting adjustments, eliminating the need for a trackside laptop. Compatible with a PC, the easy-to-use device can store seven preset maps.

Launch Control

A key advantage and a favorite for riders looking to beat their rivals for the first time is the 2023 Kawasaki KX250 Dirt Bike’s launch control technology. By delaying ignition timing in first and second gear, push-button activation helps apply the bike’s mighty power to the ground and maximize traction on surfaces like concrete starting pads. Total power is quickly restored, and normal ignition mapping begins when the rider engages third gear.


The 2023 Kawasaki KX250 Dirt Bike’s sleek aluminum perimeter frame is based on the KX450 motorcycle, designed with lightweight, agile handling and slim ergonomics in mind. Its lightweight design is made of cast, extruded, and forged components.

While many components are shared by the KX450 and KX250 frames, cast sections, such as the shock tower mount and engine hangers, were made specifically for the KX250. The frame provides an excellent stiffness balance. Using the engine as a compression member contributes to the frame’s stiffness balance.

The KX250, like the KX450, uses a swingarm to provide the required stiffness to match the frame and help improve grip on the rear wheel. The center of gravity and essential measurements, such as the swingarm pivot, output sprocket, and rear axle locations, have all been carefully selected to ensure the rear tire propels the bike forward.


For 2023, the rear and front suspension settings have been changed, which should help with cornering. With these modifications, the rider feels more planted entering a corner and receives more feedback from the front. Additionally, improved ground-holding capabilities allow the rider to maintain their chosen line through turns. The strong acceleration results from changes to the rear suspension intended to increase performance as the car exits corners.

The large-diameter 48mm KYB inverted coil-spring front forks on the 2023 Kawasaki KX250 Dirt Bike provide excellent movement early in the fork stroke. Large diameter inner tubes on the forks allow 25mm damping pistons to be used, resulting in smooth movement and firm damping. The stiffer compression damping the fork internals provide has been adjusted to offer better performance without compromising ride comfort.

Improving the characteristics of the front fork springs is facilitated by a revised height of oil on the fork. The outer tubes of the forks are coated with a Kashima coat, which creates a hard, low-friction surface to protect the inner tubes from wear and tear. It keeps the sliding surfaces smooth over time and protects the exterior from corrosion. The lubricant in the coat facilitates better overall ride quality and smoother suspension action.

A KYB shock unit at the rear completes the front fork. Dual compression adjustability on the rear shock enables independent damping tuning at high and low speeds. Firmer compression damping, which boosts performance without sacrificing the 2023 Kawasaki KX250 Dirt Bike’s renowned comfort, is made possible by new shock valving settings.

For smooth suspension action, a Kashima coat on the tank cylinder reduces friction and helps prevent wear and scratch. A new Uni-Trak® rear suspension system places the linkage arm under the swingarm, allowing for a longer back suspension stroke. The linkage ratio is the same as the KX450 motorcycle, which increases damping and absorption capabilities.

Brakes and Wheels

Petal disc brakes are one of several factory-style racing components used on the 2023 Kawasaki KX250 Dirt Bike. The large 270mm Braking® brand rotor up front provides excellent control and mighty braking power. The front brake’s advanced control and overall feedback are improved with a front master cylinder modeled after the KX450.

A 240mm braking brand disc at the rear provides maximum stopping performance and control. Petal-style discs help deflect debris and add to the athletic appearance. The caliper is protected from damage by a rear caliper protector.

The 2023 Kawasaki KX250 Dirt Bike now sports new Dunlop MX33 tires for 2023, providing better traction and engine power. For better traction and a more planted rear feel, the rear is now available in a larger 110/90-19 size, while the front size is 80/100-21.


With its ERGO-FIT® adjustable handlebar mounting system and footpegs that fit riders and riding styles, Kawasaki continues its unmatched commitment to providing riders with best-in-class comfort. A new wide-style footpeg design for 2023 is 5mm wider (front-to-back) and 3mm back, providing exceptional feel and grip while also easing the weight of the pegs.

The aluminum footpeg brackets that replaced the steel brackets in the previous design also make it lighter. The new, larger rear tire is offset by the nearly one-pound weight savings that result from suspension modifications and the reduced weight of the footpegs.

Standard equipment includes a factory-style, 1-1/8″thick aluminum Renthal® Fatbar® handlebar with four-way adjustable mounting. The handlebar can be adjusted to two positions, each 35 mm and a 180-degree offset clamp, with four separate settings to accommodate riders of various sizes.

The footpegs have two mounting positions; the lower position lowers the standard setting by an additional 5mm. When taller riders are seated, the lower posture effectively decreases the knee angle and lowers the center of gravity when standing.

Bodywork and Styling

The 2023 Kawasaki KX250 Dirt Bike’s factory-style graphics and sleek bodywork complement its improved handling and more powerful engine, making it the fastest-looking bike in the field and highlighting its excellent performance. The KX250’s bodywork features long, flat surfaces that facilitate sliding back and forth, facilitating rider movement.

To facilitate rider movement on the bike, the seams between the shrouds, seats, and side covers are as flush as possible. The petrol tank top allows for a level transition from the seat to the tank, allowing the user more movement to adjust their riding position and making it easier to sit further forward.

The most straightforward engine covers were designed to avoid obstructing the rider’s movement. The black alumite coating on the rims, gold finish on the oil cap, and two plugs on the generator cover help the 2023 Kawasaki KX250 Dirt Bike maintain its factory-style appearance.
