Cross-Country Tuned Suspension

• DOMINATE OFF-ROAD CONDITIONS: The KX™450X motorcycle's high-performance, race-ready suspension is optimized for cross-country racing, especially on aggressive trails.
• OPTIMIZED FOR CROSS-COUNTRY: A high-performance 49mm inverted Showa coil-spring fork comes directly from the KX™450 motorcycle. Front spring rates and damping settings tuned for cross-country riding offer reassuring feedback, especially when riding on challenging trails.
• ADJUSTABLE SETTINGS: The Uni-Trak® rear suspension system features a Showa shock with adjustable dual-range (high- and low-speed) compression damping, adjustable rebound damping, and adjustable preload. The linkage system mounts the suspension arm below the swingarm, allowing a long rear suspension stroke for precise tuning. As a result, riders can optimize damping and rear-wheel traction to suit conditions and personal preference.

Power & Performance

• BUILT TO STAY AHEAD: The same championship-proven engine performance found in KX™ motocross bikes propels the KX™450X motorcycle to the finish line. Stay ahead of the competition with a powerful engine that delivers broad, useable torque and strong, responsive power.
• CROSS-COUNTRY POWER: The KX™450X motorcycle's 449cc 4-stroke engine features a downdraft intake layout and centrally positioned straight exhaust port for high airflow efficiency to deliver robust power across the rev-range.
• SMOOTH POWER DELIVERY: A flat torque curve makes it easy to get on the gas sooner, delivering smooth and powerful acceleration to pass the competition and keep you ahead of the pack.
• OPTIMIZED PERFORMANCE: Engine maps are optimized for cross-country racing and are tunable using RIDEOLOGY THE APP KX™ on your smartphone. By tuning engine maps, the rider can change power delivery to best suit riding conditions and personal preference.
• QUICK STARTING: Fast, reliable starting can make or break your race, from nailing that dead-engine start to get you out front early to restarting the engine after stalling. Electric start makes it as easy as pushing a button.
