Advanced Technology

• RIDE WITH CONFIDENCE: All KX™450 advanced controls are now closer together for rider convenience. Kawasaki TRaction Control (KTRC), Power Mode Selection, and Launch Control Mode are now available at the push of a button. These features enable riders to quickly adjust power delivery and traction for riding conditions and preference. The KX450 offers superior features designed to inspire confidence.
• POWER DELIVERY: The KX™450 bike features power mode selection which allows riders to switch between two power modes (Normal or Mild response) quickly and easily. Riders can select between Normal (Full Power) and Mild response to suit riding conditions or preference. Mild response is good for riders still familiarizing themselves with the high-performance of the KX450.
• KAWASAKI TRACTION CONTROL: The KX™450 is the first KX™ model to feature Kawasaki TRaction Control (KTRC) at the push of a button. By using the traction button (T) on the left handlebar, riders can quickly and easily select from two levels (Weak or Strong) of traction control to suit riding conditions and preference. Riders may also elect to turn the system off.
• EVERY SECOND COUNTS: A factory-style launch control system helps put the KX™450 bike’s power to the ground for maximum acceleration. By pushing the Mode and Traction buttons simultaneously, riders activate the launch control system which is designed to deliver efficient race starts in low-traction conditions, making the holeshot yours for the taking.
• SMARTPHONE CONNECTIVITY: Thanks to Smartphone Connectivity, riders can adjust engine mapping straight from their phones via RIDEOLOGY THE APP KX™, without the need for extra equipment. The app also provides KX FI Calibration to check fuel volume and ignition timing, engine monitoring for checking engine metrics, a maintenance log for recording memo-style logs and many more useful functions.
• LIGHT PULL & SELF-ADJUSTING: A coned disc-spring hydraulic clutch offers light clutch pull and a wide engagement range. Large diameter plates provide enhanced fade resistance.

Chassis & Ergonomics

• MADE TO SHAVE LAP TIMES: Experience the race-winning advantage of a strong and lightweight chassis, agile handling, and exclusive ERGO-FIT® technology.
• ADVANCED STOPPING POWER: Next-level stopping power matches incredible acceleration capability. The high-performance Brembo brake system features drilled Braking/Sunstar discs (270/240mm) paired with a Brembo caliper and master cylinder at the front and a Nissin caliper and master cylinder at the rear. The high-performance system offers increased controllability on the brakes, contributing to enhanced corner entry.
• INCREASED TRACTION: Based on feedback from Kawasaki’s factory race teams, the KX™450 now features a larger-diameter rear hub. The hub’s increased rigidity allows loads to be transferred more directly to the ground, contributing to greater rear-end traction. Dunlop MX34 front and rear tires offer increased longevity, improved ground contact contributing to better cornering performance in the front, and improved bump absorption performance and increased traction in the rear.
• BALANCE MEETS PRECISION: A redesigned lightweight aluminum perimeter frame accommodates the updates to the engine’s intake and exhaust systems, while delivering a high level of both light, nimble handling and a composed character. Optimized rigidity balance contributes to increased front-end feel that translates to improved cornering performance in a wider range of conditions.
• GET A GRIP: Wide footpegs ensure excellent grip for optimum comfort and control, and make it easier to weight the pegs.
• PERFECT FIT: Find your best performance with the Kawasaki ERGO-FIT® advantage. Four handlebar positions and two footpeg positions allow you to tailor the KX™450 motorcycle to your body size, riding style, and preference.
• ERGONOMIC BODYWORK: Designed shrouds, side panels, and rear fender are firmer and eliminate hooking points, further facilitating rider movement.
• RENTHAL® FATBAR® HANDLEBAR & ODI LOCK-ON GRIPS: A factory-style aluminum Renthal® Fatbar® handlebar comes standard. Medium-compound ODI Lock-On Grips offer excellent grip feel, while their screw-type fastening system greatly facilitates the task of swapping grips.
• IMPROVED ACCESS: A quick-release side cover can be removed without tools, allowing for easier access to the air filter element.

Power & Performance

• BUILT TO WIN: The KX™450 engine delivers broad, useable torque and strong, responsive power across the rev range. From the starting gate to the finish line, this race-ready machine is built to stay ahead of the pack.
• POWER THROUGH THE FINISH: The powerful 449cc engine features a redesigned downdraft intake layout, cylinder head, and centrally positioned straight exhaust port for high airflow efficiency to deliver increased power across the rev-range.
• PULL AHEAD: A flat 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.
• RELIABLE STARTING: 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, all it takes is the push of a button to start up.

Race-Ready Suspension

• LEAVE THEM IN THE DUST: Take the lead with proven race-winning performance. The highly adjustable suspension package delivers smooth action, firm damping, and contributes to optimal traction.
• RACE READY: The high-performance 49mm inverted coil-spring fork handles suspension duties up front. The front fork's internal valving, adjusters, and oil level are fine-tuned to deliver optimized settings. The large-diameter inner tubes (the same size as on our factory motocross racers) enable the use of large damping pistons, delivering smooth action and firm damping.
• CHAMPIONSHIP PROVEN: The Uni-Trak® rear suspension system features adjustable dual-range (high- and low-speed) compression damping, adjustable rebound damping, and adjustable preload. The result is optimal damping and rear-wheel traction.
