KAWASAKI KX 450 F

KAWASAKI KX 450 F engineers have matched the high-tech engine to a new four-speed transmission. Combined with a manual, multi-disc wet clutch, the four-speed transmission enables the rider to take advantage of the engine’s inherently broad powerband on the racetrack; from accelerating out of turns to high-speed straights, the rider can use the KX450F’s precise throttle control to adjust speed nearly instantaneously. And to protect the underside of the engine and transmission, the KX450F comes with a lightweight aluminum skid place.

The KAWASAKI KX 450 F chassis has been designed to help the rider put the engine’s power to the ground. To do this, Kawasaki engineers combined their experience designing steel perimeter KX frames and techniques used to construct the Ninja® ZX™-10R sport bike chassis to create an all-new aluminum perimeter frame. Comprised of forged, extruded and cast aluminum parts, the strong twin-spar design gives the KX450F optimum balance of torsional and longitudinal rigidity.

The KAWASAKI KX 450 F utilizes newly designed, high-capacity Denso radiators, which provide superior cooling under racing conditions. With its tightly packed radiator cores and new fin design, the new radiators improve heat dispersion for consistent engine power characteristics and dependability.
