The KX450 has always been built with one goal in mind: to put riders on the top step of the podium. With over 40 years of KX heritage, Kawasaki now delivers an unrivaled MX1 category machine with a stronger engine mounted in the leanest chassis to date. On top of that, the machine has many class defining features ensuring riders reach the podium in style.
• Increased performance thanks to dry film lubricant Increased performance coating on the piston skirt, which reduces friction
between the piston and cylinder wall
• Hydraulic clutch Hydraulic clutch ydraulic clutch refinements refinements refinements aid both rider feel and clutch life under harsh racing conditions
• Coned-disc springs disc springs disc springsreplacecoil springs in the clutch, to provide lighter clutch actuation when the lever

Factory-style launch control system increases the chance of getting a good start by helping riders maximise traction when starting on a slippery surface.
Using the provided DFI couplers, riders can quickly and easily access their choice of three maps (standard, hard, soft) provided in the ECU.
Kawasaki’s first hydraulic clutch on a motocrosser offers more direct feel and lighter lever action.
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.
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.
Lightweight, compact Li-ion battery helps keep weight gain to a minimum.
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.
A choice of four handlebar positions and two footpeg positions allows riders to tailor their riding position to suit body size and preference.
Aggressive new bodywork makes the bike look more compact and is complemented by factory-style design and graphics.
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.
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.
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.
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.
Riders can choose from two positions to suit body size and preference. Adjustable footpeg brackets enable riders to lower their footpeg position 5 mm.
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.
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.
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.
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.
