2024 Kawasaki KX450 50th Anniversary Edition Totalmotorcycle.com Features and Benefits
ENGINE
The KX450 engine has always been recognized for its strength and torque character, and the lightweight engine package is even stronger in 2024. The four-stroke, single-cylinder, DOHC, liquid-cooled 449cc engine has increased engine performance thanks to a new downdraft intake and symmetrically aligned intake and exhaust. The redesigned intake increases the downdraft angle from 20° to 40° for a straighter, more direct route for air and fuel to enter the cylinder and increasing the cylinder-filling efficiency. The centrally positioned exhaust port aligns with the intake for more efficient airflow and more engine power.
With the new intake and exhaust design, Kawasaki changed the throttle body layout to optimize intake efficiency, resulting in smooth power delivery and quick engine response even when given partial throttle. The increased fuel pump pressure helps to increase rideability, and with cues taken from Kawasaki’s WorldSBK engineers, the valve train of the KX450 features finger-follower valve actuation. This allowed the use of large-diameter valves and more aggressive cam profiles, resulting in higher rev limits and strong high-rpm performance. 38mm intake valves help optimize the feel of the new engine, and DLC (Diamond-Like Carbon) coating on the finger followers helps to reduce friction and wear.
A high-performance piston, featuring the same design used by the Monster Energy Kawasaki team, contributes to increased performance across the entire rpm range. A short skirt, reinforced external ribs, and the use of a bridged-box bottom with internal bracing, adds to the light, but strong, piston design. A thicker piston top ring was added to match the increased power output from the engine, and the cylinder was placed 8.5mm forward to help reduce friction. The connecting rod was extended by 5mm to help further reduce friction, and the cylinder height and crankshaft were updated to match the new length. The oil jet angle was also changed to match the longer connecting rod, resulting in increased power.
A new center-port exhaust allows a relatively long header pipe to be maintained for robust low-end power thanks to the pipe exiting the center of the cylinder head and traveling through the frame cradle instead of to the side. With the exhaust header end moved forward, the muffler was also moved forward to help centralize mass. The muffler end is almost 3.5 inches further forward compared to the 2023 model. A flatter-shaped exhaust resonator chamber, which effectively increases exhaust pipe length and reduces exhaust noise, has been moved just over two inches inward for less interference with the rider’s leg. The new position also contributes to an easier ground reach, which is especially helpful when on the starting line.
The KX450 retains a hydraulic clutch, offering a more direct feel and less play for the rider. Coned-disc spring contributes to light clutch actuation when pulling the lever in while allowing for a wider clutch engagement range. Friction plates are offset and slightly rotated to help maintain a clean separation of the discs and help reduce drag when the clutch is engaged.
An electric start allows for a quick engine startup and is activated by the push of a button located on the handlebar near the right grip making starting easy and convenient. A lightweight, compact Li-ion battery helps keep weight down, as does an automatic centrifugal decompression system fitted to the exhaust cam, which lifts one exhaust valve to facilitate starting.
ELECTRONICS
Marking another first for the KX brand, riders can now select power modes using a Power Mode (M) selection button located on the left side of the handlebars, replacing the DFI couplers from the previous model. Riders can easily switch between two pre-programmed engine maps (Normal and Mild). The Normal map allows the rider to utilize the full power of the engine, while the Mild map reduces the power for scenarios where full power is not needed.
For the first time on a KX motorcycle, riders will now be able to connect to their motorcycle using RIDEOLOGY THE APP KX*. Users will be able to adjust their bike’s engine maps to match riding conditions and monitor what the KX450 is doing based on real-time data. Riders can also record and save maintenance and setup logs within the app.
The 2024 KX450 is the first KX model to offer Kawasaki TRaction Control, technology found on many Kawasaki street motorcycles. Using the Traction (T) button on the left handlebar, riders can quickly select between two levels of assistance (Low and Strong) based on riding conditions and preference. The ECU settings help to enhance traction by retarding the ignition when the rear wheel speed increases too quickly. Riders also have the ability to turn this feature off when not needed.
Getting ahead of the competition right out of the gate is imperative to racers, eliminating the grueling task of fighting through the pack. Similar to the system that the Monster Energy Kawasaki team utilizes, the factory-style Launch Control Mode comes standard on the KX450, giving riders the tools needed for efficient race starts in lower-traction conditions. Riders can easily activate Launch Control by pushing the Mode (M) and Traction (T) buttons simultaneously.
*RIDEOLOGY THE APP KX is not intended for use during vehicle operation. Only use RIDEOLOGY THE APP when the vehicle is not being operated and it is safe to do so.
CHASSIS
Kawasaki’s engineering team has worked hard to develop an industry-leading slim aluminum perimeter frame that is capable of accommodating the updates to the engine’s intake and exhaust while maintaining light, nimble handling and a composed character. As an evolution of the current design, the new frame boasts an optimized rigidity balance, which allows for improved cornering performance across a wide range of conditions. 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.
Several revisions were made to the frame components to contribute to the rigidity balance including the Y-joint shape and position, upper cross-pipe shape, swingarm bracket shape, and lower cross-pipe cross-sectional shape. With the new downdraft intake layout, the upper cross pipe was moved downwards so the intake could be routed above it. The lower cross pipe was moved downwards and the rear shock mounting position were moved to match. The downtube’s Y-joint was moved 125mm higher to make room for the new exhaust. Further adding to the frame’s rigidity balance is the engine, which is used as a stressed member. The revised torsional rigidity increases the front-end feel while a rider is cornering, allowing for a more planted feel and more consistent performance. The swingarm rigidity is matched to the frame and helps contribute to rear wheel traction.
The chassis balance and settings were all developed with the racer in mind. The bike’s center of gravity and dimensions were all selected so the rear tire would drive the bike forward instead of causing it to squat.
SUSPENSION & BRAKES
The braking package on the KX450 receives numerous high-grade components for 2024, including drilled petal disc brakes from the world-renowned Braking/Sunstar brand. For the first time in history, a Brembo caliper and master cylinder will adorn the front of a KX bike, encompassing a large-diameter, semi-floating 270mm front disc. This new combination results in strong front braking and increased front-end stabilization, allowing the rider to carry more speed through corners. At the rear, a 240mm disc gripped by a Nissin caliper offers the perfect balance of power and controllability.
A new, thicker front brake lever will be utilized on the 2024 KX450, allowing the rider to more easily grip the front brake and maintain more precise brake control.
The KX450 motorcycle is equipped with high-performance Showa 49mm coil spring front forks, which feature large diameter inner tubes that are the same size as those found on Kawasaki’s factory racing team’s bikes and enable the use of large damping pistons for smooth action and firm damping. A hard coating on the outer surface of the fork inner tubes helps prevent wear abrasion. The increased surface hardness coating also helps to prevent scratches and damage to the tubes. As a result of the surface remaining smoother for a longer period, the reduction of friction creates a smoother and more enjoyable ride. Incredibly precise personalized settings can be found with fully adjustable compression and rebound damping. The fork’s interval timing, adjusters, and oil level were fine-tuned to deliver the best settings possible for the new model.
On the rear suspension, a Kawasaki New Uni-Trak linkage system is designed to work in conjunction with the new shock, new aluminum frame and new swingarm. The linkage, which is mounted below the swingarm, allows for a longer rear suspension stroke and allows more precise rear suspension tuning. To accommodate the new intake, the shock unit is 32mm shorter (486mm reduced to 454mm) and the shock’s reservoir tank has been moved to the left side of the motorcycle, allowing more room for the exhaust pipe. Dual compression adjustability can be found on the rear shock, allowing high-speed and low-speed damping to be adjusted separately. The fully adjustable shock allows for settings to be personalized for riding preference and conditions. Like the front forks, the rear shock’s internal valving, adjusters and gas pressure were optimized to allow for the best performance possible.
WHEELS & TIRES
Developed with help from the factory race teams, the KX450 now features a larger-diameter rear hub, increasing 12mm in size (46mm to 58mm) and increasing the hub’s overall rigidity, allowing for greater rear-end traction. The front wheel is fitted with the new Dunlop MX34 80/100-21 51M tire, which features a new block pattern that increases longevity and improves contact with the ground. A new Dunlop MX34 120/80-19 rear tire offers more bump absorption and increased traction on the back wheel.
ERGONOMICS
Already known for its slim profile, the engineers of the 2024 KX450 took it a step further and redesigned a majority of the bodywork, offering a smoother rider interface than ever before. Newly designed shrouds, seat, side covers and rear fender allow the rider to move more confidently on the motorcycle. The seams between the shrouds, seat and side covers sit flush and the shroud design is slightly wider, but offers a more gradual taper for smoother rider movement. The tops of the shrouds curve in to eliminate any hooking points, and with the rear shock reservoir now located on the left side of the bike, the revised side cover now creates a fuller surface area for the rider to grip. A new quick-release side cover eases the process of accessing the air filter, which can now be removed without tools, and the air filter itself is now held in place using quick-release hooks.
Riders will notice more hand comfort with the addition of medium-compound ODI Lock-On grips, which offers an excellent grip feel and eases the process of changing grips with its screw-type fastening system. The grips adorn a factory-style 1-1/8” Renthal aluminum Fatbar which helps reduce vibration and harsh impacts felt on the rider’s hands and arms. The upper triple clamp has two sets of handlebar mount slots and reversible handlebar mounts, offering riders a choice between four handlebar positions: 25mm forward, 15mm forward, standard, and 10mm backward.
4-Stroke Engine
• Light piston helps minimize reciprocating weight and contribute to engine performance. The piston features a similar bridged-box bottom design featuring fully flush internal bracing as those used on the factory racers, with a short skirt and reinforced external ribs resulting in a lighter, stronger piston.
• Thicker piston top ring matches the engine’s increased power.
• The piston skirt is coated with a dry film lubricant to reduce friction between the piston and cylinder for increased performance.
• The connecting rod is 5mm longer than before to help reduce friction. The cylinder height and crankshaft were updated to match the new rod length.
• The plain bearings at the connecting rod big end reduce mechanical loss and help boost power, and now have greater crush height. This greater height combined with larger-diameter main journal bearings help maintain durability to match the increased engine performance
• Cylinder offset is 8.5mm forward to reduce friction and enable more efficient power generation.
• Wedge-shaped crank web increases offsetting moment for a balance factor close to 60 percent, which is close to the factory bike. The high balance factor contributes to reduced engine vibration, smoother power delivery and increased performance, especially at low rpm where response is noticeably snappier.
• Aluminum cylinder with chrome composite plating provides rapid heat transfer, superb wear resistance and optimum lubrication retention for increased performance and durability.
• Semi-dry sump lubrication system for quicker engine response. The majority of oil is stored in the transmission to keep excess oil away from the crankshaft and prevent power-robbing stirring loss. A shallow chamber collects oil at the bottom of the crankcase, where a scavenge pump moves it to the transmission. This allows the crank to be located as low as possible to help lower the center of gravity.
Race-tuned 4-Valve Cylinder Head
• Symmetrically aligned intake and exhaust ports increase intake and exhaust flow efficiency for increased performance.
• The intake cam was raised 7mm to allow for a more downdraft intake.
• Intake valve diameter was reduced 2mm to 38mm to optimize the power feel of the new engine.
• Finger-follower valve train designed by Kawasaki’s multi-time World Superbike Championship winning engineers allows large diameter valves, aggressive cam profiles and high rev limit for high-rpm performance.
• Finger-follower valve actuation reduces valve train mass by approximately 6.5 percent compared to tappet-style actuation, as well as reducing friction at the cam lobe. DLC (Diamond-Like Carbon) coating on the followers help prevent wear.
• Aggressive camshaft lobes have a chromium nitride coating for durability.
• 38mm intake and 33mm exhaust valves are titanium to help reduce weight.
• Chromium steel valve spring retainers are also light and provide reliable valve control at high rpm.
• When the cylinder head is cast the intake port cores are coated so that they have extremely smooth surfaces for increased intake efficiency.
ENGINE
Downdraft Intake
• Downdraft-style intake routing now has a much steeper 40˚ approach angle for a straighter approach for intake air that enhances cylinder filling efficiency and contributes to power.
• 44mm throttle body layout is optimized to match the new intake and exhaust port layout. It flows abundant air for maximum performance, especially at high rpm and overrun. A reversed orientation tilts the butterfly valve open from the top for optimum fuel atomization from the top-mounted injector.
• Fine atomizing, 12-hole injector sprays 75 micron droplets and contributes to smooth power delivery and superb engine response at partial throttle.
• Higher fuel pump pressure contributes to improved rideability.
• New airbox features a flat air filter that slides in and out of mounting grooves and is secured with quick-release hooks for easier filter maintenance.
Resonator Exhaust
• New center-port exhaust allows a relatively long header pipe to be maintained for robust low-end power. Since the pipe exits the center of the cylinder head it travels through the frame cradle instead of to the side of the frame downtube as on the previous design. With the exhaust header end moved forward the muffler could also be moved forward to help centralize mass. The muffler end is nearly 3.5 inches further forward than the previous model.
• A flatter-shaped exhaust resonator chamber, which effectively increases exhaust pipe length and reduces exhaust noise, has been moved just over two inches inward for less interference with the rider’s leg. The new position also contributes to an easier reach to the ground, which is especially
helpful on the starting line.
ELECTRONICS
NEW Power Modes
• Riders can now quickly and easily switch between Normal and Mild engine mapping in the ECU by using the Mode button on the left handlebar.
• The Power Mode button on the left handlebar replaces the DFI couplers used on the previous model so that riders can change engine mapping at the touch of a button.
• Normal mode provides full power while Mild mode softens engine response for better traction on hard-packed tracks and is a good level to use for riders just becoming familiar with the KXTM450.
• Each map can now be fine-tuned using one’s smartphone with RIDEOLOGY THE APP KX
Kawasaki Traction Control (KTRC)
• Using the Traction button on the left handlebar pod, riders can quickly and easily select between Weak and Strong levels of traction control to suit conditions and rider preference. The system can also be turned off.
• Monitoring engine speed, the ECU senses rpm spikes when rear wheel speed increases too quickly and retards ignition timing to enhance traction.
Launch Control Mode
• Similar to the system used on the Monster Energy Kawasaki factory racers, allows riders to activate a separate engine map designed to assist them get holeshots by pressing a button.
• The Launch Control Mode uses dedicated KTRC, ignition and fuel maps to provide optimal control to maximize tire grip to help riders get strong starts.
Coned Disc-spring Hydraulic Clutch
• The clutch uses a single coned disc spring instead of five coiled springs for light clutch actuation when the lever is pulled and a wide clutch engagement range that helps the rider control the clutch.
• Large diameter clutch plates and special friction plate material help to resist clutch fade. The friction plates also have offset segments to promote clean separation of the discs to help reduce drag when the clutch is disengaged.
• Kawasaki’s hydraulic clutch offers direct feel and light lever action. Less play as the clutch heats up during heavy use results in a more consistent feel
Electric Start
• Provides the convenience of quick and easy push- button engine starting.
• Powered by a lightweight, compact lithium-ion battery that helps keep weight gain to a minimum.
• Automatic centrifugal compression release system on the exhaust cam lifts one exhaust valve to facilitate starting. The system’s simple construction is light weight and highly reliable
• NOTE: Only use Lithium-ion specific battery charger to help prevent fatal battery damage.
Aluminum Perimeter Frame
• Redesigned frame accommodates the engine’s new symmetrically aligned intake and exhaust ports while continuing to deliver a high level of both light, nimble handling and a composed character. Optimized rigidity balance contributes to increased front end feel for improved cornering performance in a wider range of conditions.
• To accommodate the new center-port exhaust the front downtube Y joint was moved 4.9 inches higher. The new steeper downdraft intake layout required the upper cross pipe to be moved down below the intake, moving the lower cross pipe downwards and lowering the rear shock mount.
• The new downtube Y joint shape and position along with a new upper cross pipe shape, revised rib shape at the swingarm bracket, and new square lower cross pipe all contribute to the optimized rigidity.
• The revised torsional rigidity provides increased front end feel when cornering in a wider range of track conditions for more consistent cornering performance.
• Increased mass centralization contributes to the nimble handling feeling.
• The engine is used as a stressed member, contributing to the frame’s rigidity balance.
• Composed of a combination of forged, extruded and cast parts, the aluminum frame is designed with a balance of torsional and longitudinal rigidity for quick handling.
• Design emphasis on providing maximum traction under acceleration. Specific chassis dimensions and design (reinforcing ribs, swingarm pivot, output shaft, linkage mounts and rear axle) placed to prevent chassis squat and improve traction.
FRAME
• Even for top-level riders, controlling the massive power of the KX450 off the start requires throttle control and clutch finesse. Launch Control Mode helps riders maximize traction and increase the chance of getting a good start.
• Launch Control Mode has the greatest effect within the first few seconds of releasing the clutch off the start – the most crucial time to get ahead of rivals for better positioning going into the first corner.
• The system automatically disengages when the transmission is shifted into third gear, switching back to the normal engine map.
SHOWA 49mm Coil-Spring Fork
• Large-diameter inner tubes –the same size used on Kawasaki’s factory racers – allows large 39mm compression damping pistons and a 25mm cartridge cylinder to be used for smooth action and firm damping.
• Internal valving, adjusters and oil level were fined-tuned to match the new engine and chassis characteristics.
• Kashima Coat on the fork outer tubes creates a hard, low-friction surface that helps prevent wear abrasion on the inside of the tubes so that the sliding surfaces remain smooth for a long period of time. The lubricating material in the Kashima Coat contributes to smoother suspension action,
especially at the initial part of the stroke, for a better ride feel.
• Based on feedback from Kawasaki’s factory race teams, the 22mm front axle enhances front-end traction.
New Uni-Trak Rear Suspension
• Internal valving, adjusters and oil level were fined-tuned to match the new engine and chassis characteristics.
• With the lower shock mounting position, the shock unit was shortened 32mm and the reservoir tank repositioned to the left side to create more space for the exhaust pipe.
• Uni-Trak rear suspension linkage ratios selected to suit the chassis. The linkage mounts underneath the swingarm allowing additional rear suspension travel yet maintaining a low seat height. The additional rear travel offers improved suspension action over a wider range of track conditions.
• Dual compression adjust ability allows high speed and lowspeed damping to be tuned separately.
• The inside of the shock reservoir has a self-lubricating alumite coating that helps prevent wear abrasion and reduces friction for smoother suspension action.
SUSPENSION
With its highly-acclaimed slim ergonomics, the KXTM450’s redesigned bodywork offers an even smoother rider interface. New shrouds, side covers and rear fender are firmer and designed to eliminate hooking points with the rider’s boots and knees for easier movement.
• New quick-release side cover can be removed without tools for easier air filter maintenance.
• Now equipped with medium-compound ODI Lock-On grips [14]for increased comfort, excellent feel, and the screw-type fastening system greatly simplifies changing grips.
High-Performance Brakes
• The 270mm Braking brand petal front brake disc is now paired with a Brembo caliper and master cylinder. This combination provides strong braking force and increased controllability that contributes to enhanced corner entry.
• Thicker front lever provides better feel for more precise brake control.
• A 240mm petal rear brake disc with Nissin caliper is now used for a balance of strong stopping power and controllability.
• Petal disc shape helps remove dirt build up in pads, increasing performance.
