CARACTERÍSTICAS

CARACTERÍSTICAS CHAVE

Finger follower valve actuation

Finger follower valve actuation

With its factory style components and tuning – including the adoption of a new finger follower valve actuation system - the new engine of the KX450 is now even more powerful with an additional 3.4 PS to keep riders ahead of the pack.

Slim, Ergonomic Bodywork

Slim, Ergonomic Bodywork

All-new bodywork (except the front fender and number plate) was designed to facilitate rider movement. Long, smooth surfaces make it easy to slide back and forth. The tank is lower and flatter, making it easier to sit farther forward. Slimmer shrouds are easier to hold on to. Even the engine covers are smooth so that they do not impede rider movement.

Adjustable Ergonomics

Adjustable Ergonomics

A choice of four handlebar positions and two footpeg positions allows riders to tailor their riding position to suit body size and preference.

Electric Start

Electric Start

Being able to restart an engine quickly after a spill can mean the difference between keeping your lead, or having to fight your way back through the pack.

Increased Front/Rear Traction

Increased Front/Rear Traction

Matching the KX450’s increased power, increased front and rear traction ensure the bike can put power to the ground and get around corners quickly. A largerdiameter front axle (a hint from our racing teams) helps at the front, while revised rear suspension layout and new linkage ratios benefit the rear.

Easy Engine Tuning: DFI Setting Data Selection

Easy Engine Tuning: DFI Setting Data Selection

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

Factory-Inspired Tuning

Factory-Inspired Tuning

Works-base bridged-box bottom piston (unique Kawasaki feature used for the first time on a mass-production motocrosser on the 2010 KX450F) is just one of many features inspired by our factory racers.

Factory Styling

Factory Styling

Aggressive new bodywork makes the bike look more compact and is complemented by factory-style design and graphics.

Launch Control Mode

Launch Control Mode

Factory-style launch control system increases the chance of getting a good start by helping riders maximise traction when starting on a slippery surface. 

Stronger Brakes

Stronger Brakes

A larger-diameter ø250 mm rear disc complements the oversized ø270 mm front disc, delivering stronger stopping power. A new front brake master cylinder offers better initial control, while contributing to overall braking performance.

Light Weight & Light, Nimble Handling

Light Weight & Light, Nimble Handling

Complementing the powerful engine, light, nimble handling contributes to the KX450’s quick lap times. While the addition of electric start and the return to a coil-spring fork add weight, efforts were made to keep the weight gain to a minimum. The result is the KX450’s leanest chassis to date, and a highly-competitive, low overall weight of only 110.0 kg – a gain of only 1.3 kg.

KX FI Calibration Kit (Accessory)

KX FI Calibration Kit (Accessory)

KX FI Calibration Controller, a portable handheld calibration tool, enables riders to make changes to engine maps by plugging into the ECU without needing a PC or battery. Comes equipped with seven preset map settings.

Li-ion Battery

Li-ion Battery

Lightweight, compact Li-ion battery helps keep weight gain to a minimum.

Large-Diameter Coil-Spring Fork

Large-Diameter Coil-Spring Fork

Handling suspension duties up front is a new highperformance ø49 mm inverted coil-spring fork. The large diameter inner tubes (the same size as on our factory racers) enables the use of large damping pistons, delivering smooth action and firm damping.

Even More Powerful Engine

Even More Powerful Engine

The new engine boasts an increase in peak power of approximately 2.5 kW (3.4 PS), while a flatter torque curve makes it easier to get on the gas.

Lightweight Aluminium Perimeter Frame

Lightweight Aluminium Perimeter Frame

An evolution of the current design, the new frame features revised rigidity and includes the engine as a stressed member. A new swingarm also contributes to the revised rigidity balance and increased rear traction.

Hydraulic Clutch

Hydraulic Clutch

Kawasaki’s first hydraulic clutch on a motocrosser offers more direct feel and lighter lever action.

Adjustable Footpeg Position

Adjustable Footpeg Position

Riders can choose from two positions to suit body size and preference. Adjustable footpeg brackets enable riders to lower their footpeg position 5 mm.
