EVEN MORE 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.

Highly acclaimed for its high output and smooth power delivery (thanks to the world’s first dual injection for motocrossers and race-inspired tuning and parts like the high-performance piston with bridged-box bottom), the 2013 KX250F offers a straighter intake tract, even more high-rpm power, a choice of three easy-to-use engine map settings, and a number of changes to meet even stricter noise regulations.

249 cm3 liquid-cooled, 4-stroke Single with Dual Injectors

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.

High-revving character is complemented by superb response.

Factory-inspired tuning

A works-base bridged-box bottom piston is just one of many features inspired by our factory racers. Tuned for high performance, a more direct intake tract and other changes for ’13 yield even more high-rpm power.

Easy engine tuning: DFI Setting Data Selection (3 map choices)

Adjusting engine settings to suit conditions has never been easier than with the new DFI couplers. Plug-and-play style system is quick, easy and stress-free.

Precision engine tuning: 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.

Progressive throttle link

Lightweight 43 mm throttle body uses two shafts joined by a progressive link to give sharp response and excellent power feeling.

HIGH-SPEED CHASSIS WITH FACTORY-STYLE COMPONENTS AND TUNING

The KX250F’s slim aluminium perimeter frame is a lightweight construction composed of forged, extruded and cast parts. Chassis balance and settings were all set to suit race-experienced riders.

The centre of gravity and key dimensions (swingarm pivot, output sprocket and rear axle locations) were chosen so that the rear tyre would drive the bike forward (instead of causing it to squat). Acclaimed for its high-speed stability, the chassis is complemented by its Separate Function front Fork (SFF), which offers greatly reduced friction that contributes to increased riding comfort and improved suspension performance.

For 2013, a slimmer new frame with revised rigidity, newly designed minimalist bodywork, and a larger diameter front fork with SFF Type 2 internal construction offer improved ergonomics, lighter handling, increased rear wheel traction, a more planted feel from the front wheel, firmer damping and increased ride comfort, greater front bottoming resistance, and increased stability on the brakes or when landing jumps.

Separate Function front Fork (SFF) Type 2

Used for the first time on a mass-production motocrosser on the 11MY KX250F, the SFF locates its damping assembly in the left fork tube and a spring in the right.

For 2013, thicker fork tubes and new works-style Type 2 internal construction result in a more 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.

Slimmer rider interface

The new frame and minimalist bodywork, designed with rider ergonomics in mind, offer a slimmer rider interface and improved ergonomics.

The natural riding position makes it even easier for racers to go fast

Superior rear-wheel traction

The New Uni-Trak rear suspension system mounts the suspension arm below the swingarm, allowing a longer rear suspension stroke. The longer stroke in turn allows more precise rear suspension tuning.

Factory KX Styling

Factory-style graphics, black alumite rims, black fork guards 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 its highly tuned performance.

New minimalist bodywork

Complementing the new minimalist bodywork, new fender and front number plate designs ensure the KX250F is the sharpest looking bike in the paddock. For 2013, the rear fender is black (instead of lime green), like on our factory racers.

Factory image

Embossed design on the clutch cover designed to gradually appear as contact from riding boots wears off the paint. Engine covers are finished in silver paint, further reinforcing the KX250F’s factory image.

Rims are coated in black alumite – just like the factory racers.

Renthal handlebar

Factory-style handlebar and pad saves weight.
