Overview of the Kawasaki KX450 model range

With more Supercross and Motocross championships than any other manufacturer, the KX name is synonymous with winning. The KX450 motorcycle represents the flagship of the KX lineup, built with the sole purpose of dominating the track. Over the past four decades, we’ve learned what it takes to win and stay on top. Our dedication to building the ultimate machine is undeniable, and the KX450 represents this to the fullest.

  • POWERFUL 449 cc 4-STROKE ENGINE
  • ELECTRIC START
  • RACE-READY SHOWA SUSPENSION

FACTORY-STYLE ENGINE COMPONENTS AND TUNING

Championship-proven Performance: Recognized as the most powerful motocrosser in the paddock, the KX450 boasts innovative engine technology inspired by Kawasaki’s race machines. Features like finger-follower valve actuation and a bridged-box bottom piston that contribute to its lofty performance are backed by electric start and a hydraulic clutch, further elevating its race-winning potential.

  • SERIOUSLY POWERFUL ENGINE - Hard-hitting Power: The high-acclaimed KX450 engine delivers hard-hitting power, while its flat torque curve makes it easy to get on the gas. Finger-follower valve actuation (a valve train designed by Kawasaki’s World Superbike engineers) enables large-diameter valves and aggressive cams. Downdraft-style intake and friction-reduction efforts (like a dry film lubricant on the piston skirt) further contribute to the high performance.
  • ELECTRIC START - Reliable Starting: Being able to restart an engine quickly during a race can mean the difference between keeping your lead, or having to fight your way back through the pack. Electric start makes restarting the engine as easy as pushing a button.
  • HYDRAULIC CLUTCH - Light & Responsive: The hydraulic clutch offers direct feel and light lever action. Revised construction using coned-disc springs results in lighter clutch actuation when the lever has been pulled in, and a wider clutch engagement range, which facilitates control (especially when half-clutching).
  • ADJUSTABLE MX ECU - Easy Engine Tuning: Lightweight and designed for the rigours of off-road riding, the ECU contains multiple programmable engine maps to offer riders an advantage on the race course. Using the provided DFI couplers, riders are able to easily switch from one to another of the three engine maps to suit riding conditions. The plug-and-play style system is quick, easy and stress-free. Each of the three maps can be reprogrammed using the optional KX FI Calibration Kit. Non-current colour shown
  • LAUNCH CONTROL - Holeshot Advantage: Factory-style launch control system increases the chance of getting a good start by helping riders maximise grip when starting on a low-traction surface.

FACTORY-STYLE CHASSIS COMPONENTS AND TUNING

Light, Nimble Handling: Trimmed of all unnecessary material, this is the leanest KX450 chassis to date. Frame, suspension, brakes and ergonomics have all been optimized to make the KX450 even better equipped to turn quick lap times.

  • FRAME - Lightweight Aluminium Perimeter Frame: Complementing the powerful engine, light, nimble handling contributes to the KX450’s quick lap times. Thanks to extensive weight-reduction efforts, the lightweight aluminium perimeter frame contributes to a highly-competitive, low overall weight of only 110.2 kg.
  • SUSPENSION - Race-ready Suspension: Handling suspension duties up front is a high-performance ø49 mm inverted coil-spring fork. The large-diameter inner tubes (the same size as on our factory racers) enable the use of large damping pistons, delivering smooth action and firm damping. At the rear, New Uni Trak rear suspension contributes to superb rear-wheel traction.
  • BRAKES - Strong Stopping Power: The oversized ø270 mm semi-floating front disc complemented by a ø250 mm disc at the rear deliver strong stopping power and a high level of control.
  • BODYWORK - Slim, Ergonomic Bodywork: The narrow frame and minimalistic bodywork offer a slim riding position that facilitates control.
  • ADJUSTABLE ERGONOMICS - Get the Perfect Fit: A choice of four handlebar positions and two footpeg positions allows riders to tailor their riding position to suit body size and preference. Factory-style ø28.6 mm (1-1/8”) Renthal aluminium Fatbar helps reduce vibration and shocks transmitted to the rider, while a lower, closer grip position helps put the rider in a position that makes it easier to weight the front wheel.
