Hailing from the KX™ championship legacy, the KX™450X motorcycle has been tuned for off-road racing. The bike features off-road ready suspension for optimized feedback and traction in off-road environments. F21"/R18" wheels paired with off-road tires are equipped for off-road capability. A factory-style skid plate and a convenient side stand come equipped standard.Take it for a ride today

Proper fit is key for rider comfort and control. However, the ideal fit varies from rider to rider, depending on their physical dimensions and riding style.
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. Feeling at one with their machine, they will be able to experience how Kawasaki machines are fun and rewarding to ride.
*Adjustable parts and their range of adjustability vary by model.
Designed to assist riders by optimizing acceleration from a stop, KLCM electronically manages engine output to minimize wheelspin when moving off.
With the clutch lever pulled in and the system activated, engine speed is limited to a determined speed while the rider holds the throttle open. Once the rider releases the clutch lever to engage the clutch, engine speed is allowed to increase, but power is regulated to minimize wheelspin and help keep the front wheel on the ground. The system disengages automatically once a predetermined speed has been reached, or when the rider shifts into 3rd gear. Depending on the model, riders can choose from multiple modes, each offering a progressively greater level of intrusion.
