2025 Kawasaki KX250X Bike

• New symmetrical port cylinder head with finger-follower valve actuation
• Redesigned downdraft intake
• New piston has a flatter crown to accommodate a narrower valve angle for improved combustion
• New single-shaft primary engine balancer contributes to smoother power delivery and reduced vibration for improved throttle control, especially when exiting slower speed corners
• New symmetrically-aligned intake and exhaust ports increase intake and exhaust flow efficiency for increased power output and low to mid-range power feel
• Downdraft-style intake routing now has a slightly steeper 34° approach angle for a straighter approach for intake air that enhances cylinder filling efficiency and contributes to power
• New airbox design maximizes the potential of the dual injectors and features a slide-in air filter that is secured with quick-release hooks for easier filter maintenance
• New, lighter, KX450-based 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, plus greater composure under acceleration and braking for faster lap times
• New Showa coil spring fork and rear shock
• Slimmer bodywork and revised ergonomics; 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
• Multiple Power Modes offer riders an easily selectable choice of engine power delivery to suit riding conditions or preference; riders can now quickly and easily switch between Normal and Aggressive engine mapping in the ECU by using the Mode button on the left handlebar
• Kawasaki TRaction Control (KTRC) provides both enhanced sport riding performance and the peace of mind to negotiate slippery surfaces with confidence; 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
• Kawasaki Launch Control Mode (KLCM) with push-button activation electronically manages engine output in first and second gear to minimize wheel spin when moving off; normal ignition mapping immediately resumes and full power is restored once rider shifts into third gear
• Smartphone Connectivity via "RIDEOLOGY THE APP" allows riders to access and adjust their bike’s engine maps: fuel volume and ignition timing of the bike’s two original maps can be fine-tuned to suit conditions and/or preference; while the engine is running, features like engine rpm, throttle angle, engine intake pressure, coolant temperature, air temperature, and ignition offset can be viewed from the smartphone; maintenance and setup logs are also available
• 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

KX250X features the following differences from the KX250 (motocross) model:
• Spring rates and damping settings are optimized for cross country racing to offer increased feedback, especially when riding on aggressive trails
• Off-road specific 18-inch rear wheel allows tire to have a larger sidewall for a smoother ride over rocks and roots, plus better resistance to pinch flats when riding in such terrain
• Dunlop AT81 tires are designed specifically for the demands of off-road racing
• Standard side stand provides convenient parking out on the trail
• Sealed chain for added durability in mud and longer off-road events
• 12-volt bullet terminal for adding off-road accessories
