New Electric Start

Being able to restart your engine quickly after a stall can make or break a race. Powered by a compact and lightweight Li-ion battery and supported by an automatic centrifugal decompression system, now all it takes is the push of a button to start the KX™450.

More Powerful Engine

Increased peak power and a flatter torque curve come thanks in part to:

A new finger-follower valve train designed by Kawasaki’s World Superbike engineers

More aggressive cam profiles

Larger intake and exhaust valves

New lightweight bridged-box piston

Downdraft-style intake routing

A larger 44mm throttle body

Longer exhaust header pipe

Launch Control

Factory-style launch control system helps to put the bike’s power to the ground for maximum acceleration at the start of the race, making the holeshot yours for the taking.

Improved Torque

A flatter torque curve makes it easier to get on the gas sooner, delivering smooth and powerful acceleration to pass the competition and keep you ahead of the pack.

More Powerful Brakes

The KX™450 delivers major stopping power when you need it most thanks to the new larger-diameter 250mm petal-shaped BRAKING® rear brake rotor that complements the oversized 270mm petal-shaped BRAKING® front brake rotor. A new front brake master cylinder offers better initial control and braking performance, while the new rear brake master cylinder and hose have been revised to reduce weight.

New Front Suspension

Updates to the KX™450 contribute to smooth suspension action and a better ride feel.

New SHOWA 49mm coil spring front fork with A-KIT Technology

Titanium oxide coated inner tubes and large 39mm damping pistons

New Showa Dimplush™ finish and Kashima Coat protect outer fork tubes against corrosion and prevent wear abrasion on the inner walls for a smoother ride

New larger-diameter 22mm front axle helps improve front traction

NEW UNI-TRAK® REAR SUSPENSION

Improved damping, increased traction and more precise rear suspension tuning come as a result of:

New SHOWA Compact Design rear shock: A-KIT technology with large 30mm compression adjuster

New slim aluminum perimeter frame and new hydroformed swingarm revise rigidity to increase rear traction

New 5mm offset shock layout to optimize downdraft-style intake

Improved Ergonomics

Redesigned bodywork better facilitates rider movement.

New lower fuel tank and flatter seat give the rider greater freedom of movement when changing riding position

New radiator shrouds are slimmer at the rider’s legs for improved grip

In-mold graphics for an ultra-smooth surface

New smooth surface engine covers

Nearly flush seams between the shrouds, seat and side covers for seamless contact points

ERGO-FIT® TECH

ERGO-FIT® adjustable handlebar mounting system and footpegs enable the perfect fit to help you comfortably ride with confidence.

Power Delivery

Choose engine settings to suit your riding style or track conditions with KX™450 DFI® couplers. This plug-and-play style system allows riders to quickly and easily select from three different pre-programmed fuel injection and ignition mapping settings. Fine tune your ECU setting with factory precision with the KX FI Calibration Kit*, featuring a handheld controller that enables riders to adjust fuel mapping and store presets for various track conditions without a PC.

*Sold seperately as Kawasaki Genuine Accessory

New Hydraulic Clutch

Reduce lap times with Kawasaki’s first hydraulic clutch on the KX™450. The new clutch offers a more direct feel and an easier pull for lighter lever action, helping to reduce riding fatigue. As the clutch heats up during heavy use, minimal change in clutch play provides a more consistent and direct feel.

Redesigned Chassis

The updated lightweight aluminum perimeter frame and swingarm increase overall rigidity balance and contribute to precise cornering through excellent front-end feel and increased traction at the rear wheel.

Redesigned Footpegs

The new lighter footpegs are 5mm wider and positioned 3mm farther rearward, offering excellent grip and making it easier to weight the pegs.
