Easy engine tuning: DFI setting data selection

Easy engine tuning: DFI setting data selection

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.

Slim rider Interface

Slim rider Interface

The KX250's frame and minimalist bodywork, designed with rider ergonomics in mind, offer a slim rider interface and racer-friendly ergonomics. Complemented by new adjustable handle and footpeg positions, the natural riding position makes it even easier for racers to go fast.

Adjustable footpeg position -

Adjustable footpeg position -

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.

Progressive throttle link

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.

Separate function fork (SFF) Type 2

Separate function fork (SFF) Type 2

Used for the first time on a mass-production motocrosser on the 2011 KX250F, the SFF locates its damping assembly in the left fork tube and a spring in the right.    

High-Performance piston

High-Performance piston

A high-performance piston features the same design used on our factory racers, contributing 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.

KX FI Calibration Kit (option)

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.

New uni-trak rear suspension

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. Self-lubricating alumite coating on the tank cylinder improves wear resistanceand shock action.

Factory Styling

Factory Styling

Complementing the factory-style design and graphics, black alumite rims, black fork guards, new green highlights help create a distinctive Kawasaki identity. Green alumite finish on the suspension adjusters and green finish on some of the engine trim add to the KX250F’s high-performance image.

The holeshot advantage: Launch Control Mode

The holeshot advantage: Launch Control Mode

Like the KX450F, the MY15 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. (the Launch Control Mode map retards ignition timing, allowing tyres to gain grip in low-traction situations, and allowing riders to focus on their lines).

Powerful, high-revving dual-injection engine with factory-style tuning

Powerful, high-revving dual-injection engine with factory-style tuning

Tuned to best suit race-experienced riders, the 249 cm³ liquid cooled, 4-stroke Single's wide powerband focuses on high-rpm performance and extends way into the over-rev.

Race-ready front suspension

Race-ready front suspension

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.

Petal brake discs

Petal brake discs

New design factory-style front and rear petal brake diswcs offer strong braking performance, excellent control and high-quality sporty looks. Oversized 270mm front disc further enhances controllability.

High-speed chassis with factory-style components

High-speed chassis with factory-style components

The aluminium perimeter frame is a lightweight construction composed of forged, extruded and cast parts.

Adjustable handlebar position

Adjustable handlebar position

A choice of four positions allows riders to tailor their riding position. Factory-style Renthal handlebar and pad come standard. 

TECHNOLOGY

Launch Control Mode

Launch Control Mode

Launch Control Mode is a motocross-use start mode that helps riders get the holeshot by minimising wheel spin off the start.
