Championship - Winning 2005 Kawasaki KX250F - The 2005 model returns with updates for even better performance!

The Kawasaki KX250F competition motorcycle returns for 2005 with several engine and chassis updates, making this championship-winning motocross bike the envy of the competition.

And the KX250F is indeed worthy of such envy: in its first year of competition, Team Pro Circuit / Kawasaki / Chevy Trucks racer Ivan Tedesco rode this four-stroke Kawasaki to victory, clinching the 2004 AMA THQ Supercross Series 125cc Western Regional Championship.

2005 Kawasaki KX250F To help keep the KX250F on the leading-edge of such exhilarating power and performance, Kawasaki engineers began by making refinements to the engine. The liquid-cooled 249cc four-stroke engine has improved low and mid-range response courtesy of a modified intake port, a straightened exhaust port, and revised ignition timing for improved top-end and over-rev performance.

To help maintain an optimal performance temperature, the radiators are 40mm longer for improved cooling efficiency, and the throttle cable is revised for smoother operation to enhance rider control of the broad four-stroke powerband.

The KX250F’s quick-shifting five-speed transmission is improved with stronger third and fourth input gears, and the clutch friction plates now have fewer friction elements to provide the rider with a more direct feel. The stainless steel clutch cable and cable liner are changed for smoother operation, and a new clutch adjuster is added to the lever perch, making rider adjustments on the track quick and easy. 2005 Kawasaki KX250F

The KX250F chassis and suspension are also improved. The head pipe wall thickness is increased for improved handling and the 48mm inverted Kayaba forks have new, low-friction seals for smoother action. The fork mounting bolts have also been moved on the top triple clamp for easier maintenance.

The KX250F’s high-performance disc brakes are stronger than ever and feature new front brake pad material for enhanced performance, while a new front brake lever provides the rider with better feedback.

Changes to rider accommodations include new footpegs that are wider and offer better grip; a new seat cover with high-grip top for sitting while cornering and smooth sides for transitioning from sitting to standing; and wider handlebar mounts to help prevent bending.
