<p>KX™450F with Link Inc, Gateway Cycles, FMF graphic kit. Very nice, very low time bike! Senior ridden. 4-speed trans.</p><p style="margin-bottom: 1em;">Kawasaki, the brand that introduced the motocross world to perimeter frames and awe-inspiring powerbands, has unveiled an all-new flagship in its leading-edge KX™ motorcycle line. Every aspect of the 2006 KX450F, from its ultra-powerful four-stroke engine to the trick aluminum frame and suspension, reflects its purpose as a championship-winning race bike. Kawasaki engineers stressed every detail on the new, liquid-cooled, 449cc four-stroke engine to ensure that it provides maximum power and traction. Featuring double overhead cams, four valves and a Keihin FCR40 carburetor, it combines amazing acceleration with smooth over-rev capability so the rider can use very ounce of its incredible power on the racetrack. Hand-finished intake ports maximize intake efficiency, while lightweight titanium valves and aluminum valve retainers reduce reciprocating weight for reliable valve control at high rpm. Plus, double valve springs provide stable operation under intense racing conditions. To ensure quick and easy starting, the KX450F features both an automatic compression release and hot start system. The KX450F 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. The KX450F comes equipped with a tapered titanium exhaust pipe that expands in diameter from 38 to 41mm, contributing to its broad powerband, and the silencer features new, long-fiber packing. Kawasaki 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 KX450F 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 frame was designed so that the center of gravity and key chassis dimensions would work together to enhance the rear tire’s abi
