A revision of engine and chassis components results in 1.7 kg in weight savings, bringing the already light KX250F down to a trim 104.3 kg. 
The lighter weight and repositioned engine contribute to lighter overall handling.

Super-hard titanium coating (unique in this class) protects the fork from wear abrasion. Self-lubricating alumite coating creates a hard, low-friction surface on the outer tube, protecting the aluminium surface and further reducing friction to promote smooth fork action.

Der neu gestylte Rahmen gibt dem Bike einen aggressiven Touch und kompaktes Erscheinungsbild. Die grünen Akzente machen die neue KX250F unverkennbar zu einem Mitglied der Kawasaki-Familie.

The KX250F features a launch control system similar to that on our factory racers. With the
simple press of a button, riders can activate a separate engine map designed to ensure
efficient race starts in slippery conditions.

Using the provided FI couplers, riders can quickly and easily access their choice of three maps (standard, hard, soft) provided in the ECU.

Upper triple clamp with two sets of handle mount slots and reversible handle mounts offers riders a choice of four handle positions to choose from: 25 mm FWD, 15 mm FWD, STD and 10 mm BK.

ø270 mm front disc delivers strong stopping power and excellent controllability. The factory-style front and rear petal brake discs also contribute to high-quality sporty looks.

Linkage mounts below the swingarm for more precise suspension tuning. Dual compression adjustability offers a wide range of tuning options. Self-lubricating alumite coating on the tank cylinder improves wear resistance and shock action. For 2017, a new spring coil reduces weight while revised settings contribute to improved ride feel and increased rear-end feedback.

Aluminium perimeter frame is a narrower across the main beams, and features revised rigidity contributing to greater front-end feel.

The use of the world’s first dual injectors for a production motocrosser is a key component of the KX250F’s highly acclaimed fuel-injected performance.
Tuned for high performance, its high-revving character is complemented by superb response. For 2017, downdraft-style intake routing and reduced mechanical loss further elevate engine output.

Lightweight ECU was designed specifically to withstand the rigors of motocross racing. ECU contains three engine maps (plus a fourth for Launch Control Mode). 
Settings for the three maps can be reprogrammed with the optional KX FI Calibration Kit.

The SFF locates its damping assembly in the left fork tube and a spring in the right. ø48 mm fork tubes and works-style internal construction contribute to a planted feel at the front, increased damping performance and ride comfort, greater bottoming resistance, and increased stability when on the brakes or when landing jumps. For 2017, revised settings contribute to greater stability over braking bumps and through corners.

Adjustable footpeg brackets enable riders to lower their footpeg position 5 mm. In the lower position, centre of gravity is lowered as is the rider’s point of view, adding to both physical and psychological stability.

Natürlich haben die Ingenieure auch am Chassis und dem Bodywork Hand angelegt. Die 20 Millimeter niedrigere Tankoberfläche sowie der leichtere, im oberen Bereich sechs Millimeter schlankere, steifere Rahmen erhöhen die Bewegungsfreiheit des Piloten und verbessern das Handling.

One of the many features inspired by our factory racers, Kawasaki’s works-base bridged-box bottom piston has an updated design, optimised strength and lighter weight.
