2013 Kawasaki KX 250F

With its unstoppable character the Kawasaki KX 250 is ready to deal with any type of terrain with poise. The bike is propelled by a fuel injected, liquid cooled, 4 stroke, 249 cc engine which sends power to the rear wheel through a five speed gear box. The sound of the new 30mm shorter muffler is pretty impressive because it was designed with a 7mm wider outlet than the previous one. On the other hand, the stainless header now uses an acoustic resonator to decrease sound output and boost low-end power. The 2013 Kawasaki KX 250F is now offered with DFI map selector couplers to make the power change much faster than before.

As far as style goes, the bike comes with Factory-style graphics, black alumite rims, black front guard and rear fender, blue alumite finish on the suspension adjusters, and a blue finish on some of the engine.

Kawasaki KX 250F

Kawasaki KX 250F

Lead - Don’t follow. Even slimmer for ultimate control, the Championship winning, dual injector equipped KX250F is more trackside tuneable, powerful and rider-compliant than ever.

Separate function fork (SFF) Type 2

The KX250F is the only mass-production motocrosser featuring Showa’s Separate function fork (SFF) type 2. Thicker fork tubes and new internal construction offer increased damping performance and stability when on the breakes or landing jumps.

Factory Styling

Factory-style graphics, black alumite rims, black front guard and rear fender, blue alumite finish on the suspension adjusters, and a blue finish on some of the engine trim give the KX250F the looks to match high tuned performance.

Race-ready front suspension

Kawasaki KX 250F

A super-hard titanium coating on the outer surface of the inner forktubes combined with Kashima coat on the inside of the outer tubes reduces sliding friction and improves action, for a better ride feel.

Race-oriented brake system

Front and rear petal discs are complemented by a new front brake master cylinder and front brake pads, for stronger braking performance and control.

New uni-trak rear suspension

Linkage mounts below the swingarm for more precise suspension tuning. dual compression adjustability offers a wide range of tuning options. Kashima coat on the tank cylinder improves action. revised dumping settings match the new front fork and revised chassis balance.

Easy engine tuning: DFI setting data selection

Kawasaki KX 250F

Adjusting engine settings to suit conditions has never been easier than with the new DFI couplers. The new ECU features three engine maps (soft, standard and hard). riders can easily switch between them to suit riding conditions just by plugging in each of the 4-pin coupler.

KX FI Calibration Kit (option)

The KX FI Calibration Kit is the same kit used by Kawasaki’s works teams in Europe and the U.S. The kit enables expert riders to adjust engine characteristics (by rewriting actual data maps) to suit their preference, record riding data, and analyse their riding data to further fine-tune their settings.

High-speed chassis with factory-style components

Aluminium perimeterframe is a lightweight construction composed of forged, extruded and cast parts. Revised rigidity contributes to lighter handling and improved rear wheel traction, while a slimmer design contributes to improved ergonomics.

Even more powerful, high-revving dual-injection engine with factory-style tuning

Kawasaki KX 250F

Highly acclaimed for its high output and power delivery. The world’s first dual injection for motocrossers, offers a straighter intake tract, even more high-rpm power,and choice of three easy-to-use engine map settings.

Slim rider Interface

Slimmer new frame, new minimalist bodywork, a flatter tank-seat line and new handle grips offer a slimmer riding position and improved ergonomics, making it even easier for riders to go fast.

High-Performance piston

High-performance piston, featuring the same design used on our factory racers, contributes to improved performance at all rpm. A short skirt, reinforced external ribs and the industry’s only mass-production use of a bridged-box bottom, featuring fully flush internal bracing, result in a lighter, stronger piston.

Next-level power

Adding to the highly acclaimed power offered by the KX250F’s dual injectors - a world first for motocrossers - more direct intake routing and wider porting further increases high-rpm performance.

Progressive throttle link

The 43 mm throttle body makes use of a progressive throttle link to deliver airflow in much the same way as would a FCR carburetor. Using two linked shafts, the throttle body opens more quickly after the 3/8 open position, delivering sharp response and excellent power feeling.
