2022 Kawasaki KX450: THE BIKE THAT BUILDS CHAMPIONS.

Introducing the 2022 Kawasaki KX450…

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.

Featuring: 449cc 4-stroke engine with increased performance, new coned disc-spring hydraulic clutch, new Renthal Fatbar handlebar.

As the flagship model in the Kawasaki KX lineup, the 2022 Kawasaki KX450 is built with race-winning components to help get Kawasaki riders to the top step of the podium. Tuned to best suit race-experienced riders, the 449cc liquid-cooled, four-stroke engine boasts an abundance of power along with a slim aluminum perimeter frame, Showa A-KIT technology suspension, coned disc-spring hydraulic clutch, and electric start to deliver the ultimate championship-winning package.

The KX™450 has a potent engine mounted in a lean chassis for quick lap times to put its riders on top of the podium. Featuring electric start, easy-pull hydraulic clutch, and 49mm Showa coil spring forks with A-KIT technology, the KX450 is a strong contender for premiere-class supremacy.

 

 

2022 Kawasaki KX450 Totalmotorcycle.com Key Features
  • ENGINE PERFORMANCE
  • CONED DISC-SPRING HYDRAULIC CLUTCH
  • LOW-FRICTION ENGINE WITH FINGER-FOLLOWER VALVE ACTUATION PRODUCES POTENT POWER
  • ELECTRIC START PROVIDES EASY STARTING AND QUICK RESTARTS DURING COMPETITION
  • CONED DISC-SPRING HYDRAULIC CLUTCH PROVIDES CONSISTENT FEEL WITH A LIGHT PULL THROUGHOUT A MOTO
  • PERIMETER FRAME CONTRIBUTES TO LIGHT, NIMBLE HANDLING
  • LARGE-DIAMETER COIL SPRING FORK SIMPLIFIES SET-UP

The 449cc lightweight engine package utilizes input derived directly from the Monster Energy Kawasaki race team, producing peak power and a torque curve that makes it easy to get on the gas early. The potent KX450 engine features an electric start activated by the push of a button and powered by a compact Li-ion battery. A lightweight finger-follower valve actuation design comes by way of Kawasaki’s top-level road racing technology and World Superbike engineers, enabling larger-diameter valves and more aggressive cam profiles. A close-ratio five-speed transmission is paired with a high-capacity coned disc-spring hydraulic clutch that helps facilitate control and provide a consistent feeling even under heavy use.

A slim aluminum perimeter frame provides precise cornering through excellent front-end feel and agility when riding at high speeds. The frame’s lightweight construction is composed of forged, extruded, and cast parts, while the engine is used as a stressed member and adds to the frame’s rigidity balance. Engineers carefully selected the dimension of the swingarm pivot, output sprocket and rear axle locations to focus on the center of gravity and balanced handling.

High-performance 49 mm coil spring front forks with A-KIT technology can be found up front, featuring large diameter inner tubes that are the same size as those found on the machines of Kawasaki’s factory racing team. The forks enable the use of large damping pistons for smooth action and firm damping. In the rear, a new Uni-Trak linkage system is connected to the Showa Compact Design rear shock that boasts A-KIT technology with large diameter compression adjusters.

An oversized 270 mm, petal-shaped front brake rotor from the renowned manufacturer, Braking, is fitted to perfectly complement the powerful engine of the KX450. The rear is equipped with a 250 mm petal-shaped Braking rotor coinciding with the large front disc.

Kawasaki continues its unmatched commitment towards providing riders with class-leading ERGO-FIT comfort thanks to its adjustable handlebar mounting system and footpegs to fit a variety of riders and riding styles. The factory-style 1-1/8” Renthal Fatbar handlebars feature four-way adjustable mounts with 35 mm of adjustability to suit different sized riders. The footpegs feature dual-position mounting points, with a lower position that reduces the standard setting by an additional 5 mm, reducing the knee angle when taller riders are seated.

Complementing the championship-proven technology, the 2022 KX450 maintains its aggressive styling along with in-mold graphics on the radiator shrouds that result in an ultra-smooth surface and racy look needed to finish at the top of its class. The sleek bodywork has been molded to match the V-mounted radiators and narrow chassis design, helping facilitate rider movement and making it easy to slide back and forth.

 

 

 

 

 

2022 Kawasaki KX450 Totalmotorcycle.com Features and Benefits

Renthal Fatbar
A factory-style ø28.6 mm Renthal aluminium Fatbar, a popular aftermarket part, is now a standard feature.

Hydraulic Clutch
Kawasaki’s first hydraulic clutch on a motocrosser offers more direct feel and lighter lever action.

KX FI Calibration Kit (Accessory)
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.

Light Weight & Light, Nimble Handling
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.

Electric Start
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.

Easy Engine Tuning: DFI Setting Data Selection
Using the provided DFI couplers, riders can quickly and easily access their choice of three maps (standard, hard, soft) provided in the ECU.

 

KLCM (Kawasaki Launch Control Mode)

Designed to assist riders by optimizing acceleration from a stop, KLCM electronically manages engine output to minimize wheel spin when moving off. With the clutch lever pulled in and the system activated, engine speed is limited to a determined speed while the rider holds the throttle open. Once the rider releases the clutch lever to engage the clutch, engine speed is allowed to increase, but power is regulated to minimize wheel spin and help keep the front wheel on the ground. The system disengages automatically once a predetermined speed has been reached, or when the rider shifts into third gear. Depending on the model, riders can choose from multiple modes, each offering a progressively greater level of intrusion.

 

ERGO-FIT

Proper fit is key for rider comfort and control. However, the ideal fit varies from rider to rider, depending on their physical dimensions and riding style.

ERGO-FIT is an interface system designed to allow riders to find their ideal riding position. Various points of the chassis interface (the handlebar, footpegs and seat, etc.) can be adjusted through a combination of interchangeable parts and parts with adjustable positions. This enables a wide range of riders to find a riding position that offers both comfort and control. Feeling at one with their machine, they will be able to experience how Kawasaki machines are fun and rewarding to ride. *Adjustable parts and their range of adjustability vary by model.
