The 2020 Kawasaki KX 250 has broken cover! The all-new machine features more power, an updated frame and 48 mm KYB fork among other upgrades.
ENGINE
NEW engine with increased peak power

DFIR COUPLERS
Contributing to the race-winning engine characteristics, the digital fuel injection system of the KX250 features a coupler package that has set the industry standard. Each KX250 motorcycle comes standard with three different couplers, easily allowing riders to select pre-programmed fuel injection and ignition mapping to suit their riding style or track conditions. The four-pin DFIR couplers select maps that are designed for standard, hard or soft terrain settings. Changing the engine map is as simple as connecting the coupler cap of choice. For riders looking to fine tune their ECU settings, the KX FI Calibration Kit (Handheld) is offered as a Kawasaki Genuine Accessory, and provides access to the fully programmable ECU. The handheld device eliminates the need for a trackside laptop and gives riders the ability to create custom maps for precise adjustment of fuel and ignition settings. The user-friendly device can store up to seven preset maps and is PC-compatible.
LAUNCH CONTROL
The launch control system of the KX250 motorcycle is a major advantage and favorite for riders who are focused on getting to the first turn ahead of their competition. The push-button activation retards ignition timing in
first and second gear, helping maximize traction on slippery surfaces like concrete starting pads and put the bike¡¦s potent power to the ground. Once the rider shifts into third gear, normal ignition mapping immediately resumes and full power is restored.
CHASSIS
NEW lower front engine mounts
The slim aluminium perimeter frame uses a lightweight construction composed of forged, extruded and cast parts that contribute to light, nimble handling. Thanks to new lower front engine mounts, changing from a through bolt to stud bolts at the front of the crankcase, the overall frame rigidity has been revised with improved ability to absorb bumps. The center of gravity and key dimensions such as swingarm pivot, output sprocket and rear axle locations have all been carefully selected so that the rear tire drives the bike forward.
SUSPENSION & BRAKES
NEW 48 mm KYB coil-spring fork
NEW KYB shock unit complements front fork
NEW Uni-TrakR rear suspension link
NEW stiffer front and rear spring rates
NEW revised front brake pad material
NEW larger-diameter 250 mm rear disc
NEW rear brake master cylinder
For 2020, the KX250 is equipped with new large diameter 48 mm KYB inverted coil-spring front forks that offer improved action at the initial part of the fork stroke. The forks feature large-diameter inner tubes, enabling the use of 25 mm damping pistons and delivering smooth action and firm damping. A Kashima Coat on the forks¡¦ outer tubes creates a hard, low-friction surface to help prevent wear abrasion on the inside of the tubes, ensuring the sliding surfaces remain smooth over time, while protecting the outside against corrosion. The lubricating material in the coat contributes to smoother suspension action and a better overall ride feel.
On the rear, a new KYB shock unit complements the new front fork. The rear shock features dual compression adjustability, which allows high-speed and low-speed damping to be tuned separately. Kashima Coat on the tank cylinder helps prevent wear abrasion and reduces friction for smoother suspension action. A new Uni-TrakR rear suspension system mounts the suspension arm below the swingarm, allowing a longer rear suspension stroke. The longer stroke allows for more precise suspension tuning. In order to match the KX250¡¦s more powerful engine, the front forks and rear shock feature stiffer overall spring rates.
Contributing to the numerous factory-style racing components on the KX250 motorcycle are petal disc brakes. Up front is an oversized 270 mm BrakingR brand rotor, which delivers strong braking force and superb control. A revised front brake pad material, like that found on the KX450, delivers linear brake force application, helping to facilitate control.
On the rear, a new larger-diameter 250 mm Braking brand disc contributes to stronger stopping power, complementing the large front disc. A lighter rear brake master cylinder, like those found on the KX450 motorcycle, powers the larger disc. The petal style discs contribute to both sporty looks and help deflect debris. A rear caliper guard helps protect the caliper from damage.
ERGO-FITR Adjustable Components
The handlebars feature four-way adjustable mounts. The multi-position handlebars offer two mounting holes with 35 mm of adjustability, and the 180-degree offset clamps boast four individual settings to suit different size riders.
The footpegs feature dual-position mounting points, with a lower position that reduces the standard setting by an additional 5 mm. The lower position effectively lowers the center of gravity when standing, and reduces knee angle when taller riders are seated.
BODYWORK & SEAT
NEW factory-inspired green bodywork
Complementing the improved power and precise handling of the KX250 is minimalistic bodywork that includes slim radiator shrouds for an aggressive race-ready look. A flat fuel tank and seat design help to aid in a more seamless design, making it easy for riders to move around on top of the bike.
For 2020, the number plates and airbox of the KX250 motorcycle have been updated to the color green, resembling the same look found on the bikes used by the factory racing team. The front and rear fenders and fork guards implement a sharp design that makes the bike look more compact. Adding to the distinctive Kawasaki factory race team look is a green oil cap, generator cover plugs, green alumite suspension adjusters and black alumite rims.
