THE BIKE THAT BUILDS CHAMPIONS

A high-performance 49mm inverted Showa coil-spring fork handles suspension duties up front, with optimized suspension settings for improved shock absorption. The fork's internal valving, adjusters, and oil level are finely tuned, and the large-diameter inner tubes (the same size as on our factory motocross racers) enable the use of large damping pistons for smooth action and firm damping.

An updated New Uni-Trak® rear suspension system features a Showa shock with adjustable dual-range (high- and low-speed) compression damping, adjustable rebound damping, and adjustable preload. The result is optimal damping and rear-wheel traction. A new linkage guard helps protect the rear suspension.

A redesigned seat and slim shrouds enhance appearance and ergonomics, while a larger 1.98-gal fuel tank adds cross-country-ready capability.

A high-performance front and rear Brembo brake package delivers strong, consistent stopping power. Up front, a Brembo brake caliper and master cylinder are complemented by a steel-braided brake line that sharpens feel and controllability, while new rear Brembo brake components help smooth out corner entry for quicker cornering.

The KX™450FX meets the tough demands of cross-country racing. Cross-country wheels (21-in front/18-in rear) are paired with specific Dunlop Geomax AT81 tires developed for GNCC racing.

With revised intake and exhaust systems and optimized fuel injection settings, the new KX™450FX engine improves performance with a more aggressive engine feeling and more power at mid–high rpm.

The revised exhaust system optimizes power delivery across the rev range, helping the KX™450FX pull hard through acceleration and maintain strong top-end performance down the straight.

Power Mode Selection allows riders to switch between 2 power modes (Normal or Mild) quickly and easily. Using the Power mode (M) button on the left handlebar, riders can select between Normal and Mild response to suit the current riding conditions or preference. These 2 maps, initially set to the same configuration, can be selected via RIDEOLOGY THE APP KX™2.

The KX™450FX motorcycle features Kawasaki TRaction Control (KTRC) for superior performance. Using the KTRC mode (T) button on the left handlebar, riders can select from Mode 1, Mode 2, or OFF to suit the current riding conditions or preference. The setting for both modes is initially the same, but the level of intervention for each mode can be set via RIDEOLOGY THE APP KX™2.

A factory-style launch control system helps put power to the ground for maximum acceleration. Riders can activate Launch Control Mode by pressing the Mode and Traction buttons simultaneously. Using RIDEOLOGY THE APP KX™2, riders can select from 3 intervention levels and adjust rev-limit settings to suit the current riding conditions or preference.

Every curve and line of the 2027 KX™450FX is shaped for victory. Updated bodywork with smooth surfaces fit the rider to let them move freely. Compact athletic look, slim proportions, and clean lines—it’s a purpose-built design.

Experience the winning advantage of Kawasaki-exclusive ERGO-FIT® adjustable components. Riders can choose between 4 handlebar positions and 2 footpeg positions, tailoring their riding position based on body size and preference.

Medium-compound ODI Lock-On grips deliver excellent grip feel with a screw-type fastening system that makes changing grips quick and easy.

A quick-release side cover can be removed without tools, allowing for easy access to the air filter element.
