HARD-HITTING FUEL-INJECTED POWER

Fuel-injected 449 cm³ liquid-cooled, 4-stroke Single delivers hard-hitting power from low- through high-rpm.

The broad powerband and responsive throttle offer a broad spread of torquey response that enables racers to get on the gas and go even from down low.

In addition to the inherent benefits, fuel injection contributes to the 2013 KX450F’s lag-free acceleration, especially after landing jumps.

Already featuring race-inspired tuning and parts like the high-performance piston with bridged-box bottom, for 2013 engine fine-tuning and revised ECU settings offer increased performance, especially ultra-low to mid range torque.

Factory-racer-engine-tuning

Factory-racer engine tuning

Works-base bridged-box bottom piston (unique Kawasaki feature used for the first time on a mass-production motocrosser on the 10MY KX450F) is just one of many features inspired by our factory racers.

For ’13, fine-tuning to the piston, intake cams and ECU settings result in increased performance, especially ultra-low to mid range torque.

Launch-Control-Mode

The holeshot advantage: Launch Control Mode

The KX450F 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.)

DFI-Setting-Data-Selection

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

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

 


KX-FI-Calibration-Kit

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

Progressive throttle link

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

Battery-less-fuel-injection-system

Battery-less fuel injection system

Designed specifically for motocrossers, the fuel injection system incorporates a small lightweight ECU and operates without a battery to further eliminate unnecessary weight. And of course, fuel injection eliminates the need to adjust engine settings to suit track and climate conditions.

FACTORY-STYLE CHASSIS COMPONENTS AND TUNING

The KX450F’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.

For 2013, chassis fine-tuning and the motocross industry’s first mass-production use of a Pneumatic Spring Fork offers lighter weight, easier adjustability and a wider setting range to complement the KX450F’s highly acclaimed high-speed stability, light handling and racer-friendly adjustable ergonomics.

Pneumatic-Spring-Fork

Next-generation suspension: Pneumatic Spring Fork

The KX450F is the first mass-production motocross to feature KYB’s Pneumatic Spring Fork (PSF), replacing the main springs in each fork tube with pressurised air.

Compared to a standard fork, the PSF lighter, easily adjustability, has a wide setting range, features reduced friction, increased bottoming resistance and improved road holding

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.

Kashima Coat on the tank cylinder improves action. For ’13, revised
damping settings match the new front fork.

Slim-adjustable-rider-interface

Slim, adjustable rider interface

The KX450F’s frame and minimalist bodywork, designed with rider ergonomics in mind, offer a slim rider interface and racer-friendly ergonomics.Complemented by 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, CofG is lowered as is the rider’s point of view, adding to both physical and psychological stability.

Wave petal disc brakes

Wave petal disc brakes

The KX450F features petal brake discs front and rear. In addition to helping reduce unsprung weight, the wave shapes of the petal discs help clean the brake pads for more efficient braking performance.

Choice-of-four-handlebar-positions

Choice of four handlebar positions

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

13KX250Z_201LIMIRB00D_C

Factory KX Styling

Complementing the minimalist bodywork, new fender and front number plate designs ensure the KX450F remains the sharpest looking bike in the
paddock.

- For 2013, the rear fender is white (instead of lime green), like on our factory racers.

- Factory-style graphics complement the KX450F’s highly tuned performance.

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

- Blue finish on the oil cap and the two plugs on the generator cover further contribute to factory looks.

- 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 KX450F’s factory image.
