The KX™ legacy represents a long line of champions. The drive to produce more has not slowed down. Our flagship KX™450 motorcycle offers next-level engineering and power to dominate the track. Over the decades, we've learned what it takes to win and stay on top. The KX450 embodies this legacy to the fullest.
The KX™450 motorcycle engine delivers broad, useable torque and strong, responsive power across the rev range. From the starting gate to the finish line, this race-ready machine is built to stay ahead of the pack.
The powerful 449cc engine features a downdraft intake layout and centrally positioned straight exhaust port for high airflow efficiency to deliver robust power across the rev-range.
A flat torque curve allows for smooth and powerful acceleration, so you can pass the competition and stay ahead of the pack.
Take the lead with proven race-winning performance. The highly adjustable Showa suspension package delivers smooth action, firm damping, and contributes to optimal traction.
The high-performance 49mm inverted Showa coil-spring fork handles suspension duties up front. The fork's internal valving, adjusters, and oil level are fine-tuned to deliver optimized settings. The large-diameter inner tubes (the same size as on our factory motocross racers) enable the use of large damping pistons, delivering smooth action and firm damping.
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.
A lightweight aluminum perimeter frame delivers a high level of both light, nimble handling and a composed character.
A factory-style aluminum Renthal® Fatbar® handlebar comes standard. Medium-compound ODI lock-on grips offer excellent grip feel, while their screw-type fastening system greatly facilitates the task of swapping grips.
