2024 Kawasaki KX250: LIGHTWEIGHT AND NIMBLE.

Introducing the 2024 Kawasaki KX250…

The KX250 motorcycle is designed for experienced motocross racers seeking the winning edge with superb power and handling plus readily adjustable ergonomics to make it easy to fit a wide range of riders. The KX250 is built to keep Kawasaki KX motorcycles as the winningest brand in AMA MX/SX racing and the bike that builds champions.

Tuned for race-experienced riders, the 2024 KX250 is powered by a 249cc liquid-cooled, four-stroke engine that is designed to achieve strong performance across the rev-range and result in quick lap times and excellent holeshot performance. The KX250 continues to utilize the finger-follower valve actuation – a valve train designed by Kawasaki’s World Superbike engineers – to help achieve a high rev limit that allows for the use of more aggressive cam profiles and contributes to high rpm performance. A 14.1:1 bridged-box piston features a dry film lubricant coating on the piston skirts to reduce friction and help with the bedding-in process. Dual injectors complement the powerful engine and increase engine output at high rpm.

The use of a coned disc-spring hydraulic clutch provides a consistent feeling during heavy use.

A slim aluminum perimeter frame was designed with lightweight, nimble handling, and slim ergonomics in mind. The lightweight construction is composed of forged, extruded, and cast parts for optimized rigidity. Large-diameter 48mm KYB inverted coil-spring front forks enable the use of 25mm damping pistons, delivering smooth action and firm damping. A Kashima Coat on the forks’ outer tubes helps reduce friction and prevent wear abrasion. On the rear, a KYB shock unit complements the front fork and features dual compression adjustability.

Stopping the powerful KX250 engine is a 270mm Braking brand front rotor, which delivers strong braking force and superb control. A 240mm Braking brand rear disc contributes to controllability and offers optimized stopping performance. Dunlop MX33 tires offer excellent traction and have been fitted in 80/100-21 front and 110/90-19 rear sizing.

Kawasaki continues its unmatched commitment towards providing riders with class-leading comfort thanks to its ERGO-FIT adjustable handlebar mounting system and footpegs to fit a variety of riders and riding styles. A factory-style 1-1/8” thick aluminum Renthal Fatbar handlebar comes standard and features four-way adjustable mounts. The multi-position handlebars offer two mounting holes with 35mm of adjustability, and the 180-degree offset clamps boast four individual settings to suit different sized riders. The footpegs feature dual-position mounting points, with a lower position that reduces the standard setting by an additional 5mm.

Sleek bodywork with factory-style graphics help ensure that the KX250 is the sharpest-looking bike in the paddock and further reflects its highly-tuned performance. The bodywork on has been designed to facilitate rider movement with long, smooth surfaces that make it easy to slide back and forth.

2024 Kawasaki KX250 Totalmotorcycle.com Features and Benefits

4-Stroke Engine
• The piston features the same bridged-box bottom design used on our factory racers. A short skirt, reinforced external ribs and a bridged-box bottom, featuring fully flush internal bracing, results in a lighter, stronger piston.
• Thick cylinder wall for rigidity to prevent deformation and reduce mechanical loss.
• Connecting rod design decreases the piston’s lateral force on the cylinder walls to reduce mechanical loss and contribute to performance.
• Light crank web for quick revs.
• Low-friction plain bearings at the connecting rod big end reduce mechanical loss and help boost power.
• Cylinder offset is 3mm forward to reduce friction and enable more efficient power generation.
• Upright engine orientation helps straighten the intake path. The downdraft-style intake routing fills the cylinder more efficiently, contributing to power production.
• Plateau honing of the cylinder bore provides a smooth surface to help reduce mechanical loss.
• Molybdenum coating on the piston’s outer surface helps reduce mechanical loss and resists wear. Striation helps retain oil to minimize sliding friction.
• Aluminum cylinder with chrome composite plating(KP) provides rapid heat transfer, superb wear resistance and optimum lubrication retention for increased performance and durability.
• Semi-dry sump(KP) 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. With only a shallow chamber to collect oil at the bottom of the crankcase, where a scavenge pump moves it to the transmission, the crank is located as low as possible to help lower the center of gravity.
• Twin oil pumps ensure proper lubrication and oil scavenging for optimum performance.
• Radiators are turned inward 10˚ which narrows to the KX250’s already slim profile. At transfer, superb wear resistance and optimum lubrication retention for increased performance and durability.

ENGINE

Race-tuned 4-Valve Cylinder Head(KP)
• Finger-follower valve train designed by Kawasaki’s multitime World Superbike Championship winning engineers allows aggressive cam profiles and high rev limit for superb high-rpm performance.
• Finger-follower valve actuation reduces valve train mass (intake is 3.5 percent lighter, exhaust is 4.3 percent lighter) 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.
• Straight intake ports contribute to intake efficiency to help boost performance throughout the powerband.
• Special valve seat material helps prevent wear on the titanium valves.
• Located on the exhaust camshaft, the Automatic Compression Release (KACR)(KP) allows for easy starting.

KAWASAKI DFI SYSTEM WITH DUAL INJECTORS
• Big 44mm throttle body diameter flows abundant air and contributes to top-end performance.
• Downstream injector located on the bottom of the intake duct for quick throttle response, while the position and angle the upstream injector matches the airbox design to contribute to top-end performance.
• Tapered intake funnel contributes to top-end performance.
• Intake duct angle optimized for a straight approach for intake air, which improves cylinder-filling efficiency and contributes to performance.
• A Kawasaki innovation introduced in 2012, dual, fine atomizing fuel injectors help deliver both instant throttle response and strong power throughout the rev range. One injector is located downstream of the throttle valve and the second, upstream injector is located close to the airbox.
• The downstream injector provides smooth, instant response while the upstream injector provides the power boost. As rpm and throttle position increase, primary operation switches from the downstream injector to the upstream injector. In lower gears (first and second) the switch is gradual, while in higher gears it is instantaneous.
• 44mm throttle body is compact to shave weight and provides easy starting, sharp throttle response, stable fuel delivery over jumps and whoops, and automatically compensates for changing atmospheric conditions.
• To ensure a stable fuel supply during hard riding the fuel pump features a unitized plastic fuel filter cover.

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.

Coned Disc-spring Hydraulic Clutch
Kawasaki’s hydraulic clutch offers more direct feel and lighter lever action. Less play as the clutch heats up during heavy use results in a more consistent feel. 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. The friction plates also have offset segments to promote clean separation of the discs to help reduce drag when the clutch is disengaged.

Easy DFI Tuning
• Riders can change DFI settings by simply replacing a coupler located on the right side of the steering stem. Riders can choose between Standard, Hard, or Soft terrain settings to suit riding conditions.
• Further tuning options are available for more advanced users who wish to use the optional Kawasaki KX FI Calibration Kit (hand held).

Easy-to-Use KX FI Calibration Kit (Optional)
• Accessory KX FI Calibration Kit features a handheld Controller that enables users to adjust engine characteristics trackside simply by plugging the controller into the engine’s ECU.
• The kit’s user interface is easy to understand and easy to use.
• Seven different maps come loaded on the Controller to adjust the ECU to suit track conditions. Additional maps can be created and stored on the hand held controller, or on a PC with data transfer between the Controller and PC performed via SD card.
• When connected to the ECU, the Controller can be used to display the status of a running engine.
• Can be used on all KX models equipped with DFI.

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 map retards ignition timing, allowing the tire to gain grip in low traction situations to help 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.
• Activated by pressing and holding the launch control button, located at the left handlebar, for two seconds or more while in neutral, first or second gear. When activated, the indicator lamp next to the button flashes quickly to let the rider know the system is engaged.
• The system automatically disengages when the transmission is shifted into third gear, switching back to the normal engine map.
• The Launch Control Mode indicator light also serves as a warning light if the DFI system malfunctions.

CHASSIS
Lightweight Aluminum Perimeter Frame(KP)
The frame design and construction contributes to the KX250’s light weight, light handling, slim ergonomics and optimum rear wheel traction.
• While many parts are common with the KX450’s frame, cast parts like the shock tower mount and engine hangers were designed specifically for the needs of the KX250.
• Engine is used as a stressed member, contributing to the frame’s rigidity balance.
• Steering head area with optimized rigidity, main frame rail cross-sections, wide lower frame rails and the line for the swingarm brackets contribute to the overall rigidity balance.
• Swingarm delivers the rigidity to match the frame, and contributes to rear wheel traction.
• Chassis balance and settings are all set to suit race-experienced riders.
• The frame is slim at the main spars for easy rider movement.
• Down-tube combines a forged front portion with cast aluminum rear piece for superb front-end feel.
• 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 and stability.
• 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.

RACE-READY SUSPENSION
Kayaba Coil-Spring Fork
• Fork settings match the frame rigidity, contribute to bump absorption performance and help maximize traction.
• High-performance 48mm inverted coil-spring fork has smooth action throughout the fork stroke.
• The large-diameter inner tubes allow large 25mm damping pistons to be used so a firm damping force can be achieved with a lower internal pressure. This allows firmer damping performance and increased riding comfort.
• Kashima Coat creates a hard, low-friction surface on the inside of the fork outer tubes to help prevent wear abrasion and keep the sliding surfaces smooth for a long time. The lubricating material in the coating contributes to smoother suspension action, especially at the initial part of the stroke, and a better ride feel.
New Uni-Trak Rear Suspension
• Kayaba shock complements the KYB fork.
• Shock settings match the frame rigidity balance to help maximize traction.
• New Uni-Trak rear suspension mounts underneath the swingarm, allowing additional rear suspension travel yet maintaining a low seat height. The additional travel offers improved suspension action over a wide range of track conditions.
• Dual compression adjustability allows high speed and low-speed damping to be tuned separately.
• The inside of the shock reservoir has friction reducing Kashima Coat for improved suspension action.

Big Brakes
• 270mm Braking brand petal front brake disc provides superb stopping power.
• Front master cylinder from the KX450 provides superb initial control while contributing to overall braking performance feedback.
• Front brake pads are also shared with the KX450 for linear brake force application and better control.
• Rear disc diameter is 240mm to optimize performance and contribute to controllability.

Slim, Adjustable Ergonomics
• Elongated design radiator shroud creates a smooth, non-interrupted surface between the rider’s legs to facilitate rider movement.
• The KX graphics use an in-mold process to seal the graphic into the shroud plastic for greater longevity and an ultra-smooth outer surface.
• The top of the fuel tank is low so the seat is flat for freedom of movement and sliding forward on the motorcycle.
• The footpeg brackets can be mounted in two positions, allowing the rider to change footpegs height by 5mm.
• Bodywork features long, smooth surfaces and a flat tank-seat line designed to facilitate rider movement and control.
• Slim shrouds are positioned close to the frame and designed to be slim where they come in contact with the rider’s legs. The single-piece design also enhances the rider’s ability to grip with the legs.
