REFINED POWER DELIVERY FOR IMPROVED HOLESHOT PERFORMANCE
A host of features and improvements make the 2008 Kawasaki KX™450F motocrosser easier to ride and more
reliable than ever. A newly-revised powerplant and improved shifting highlight the improvements made to
the dominant AMA and World Supercross GP Championship winner.
With little doubt about the ample power of the KX™450F the 2008 engine received smoother, more user-friendly
and linear low-rpm throttle response and torque delivery. These changes result in reduced fatigue, allowing
riders to go faster for more laps – and isn’t that what it’s all about? The improvements were achieved with
new wedge-shaped crank webs, combined with a new heavier flywheel, resulting in reduced engine vibration and
better low-end performance. Reliability of the engine was enhanced via a new connecting rod material with a
harder surface, a revised gear ratio and rotor on the oil pump for increased oil circulation and the
piston-cooling oil jet was also redesigned to prevent oil from being trapped under the piston.
The bottom end changes are coupled with a new shift cam shape and a wider track on the shift drum to permit
easier and more consistent gear selection in the KX™450F’s five-speed transmission. An ultra-smooth coating
on the intake ports improves intake efficiency and throttle response, while revised ignition data provides
easier restarting and a new five-bolt oil pump cover rounds out the engine upgrades.
Already a great handling motorcycle, the 2008 KX™450F further benefits from new engine mounts spaced 10mm
farther from the engine. This allows a slight decrease in torsional frame rigidity, making for quicker
turning and increased rear wheel traction.
Complementing the chassis change, the Kayaba fork and shock settings were fine-tuned to improve the
front / rear balance for quicker turning and slightly stiffer settings were made to improve the bottoming
characteristics. The overall suspension action is even smoother now through the addition of the
friction-reducing Kashima Coat treatment on the inside surfaces of the outer fork tubes and the shock
reservoir.
The 2008 KX™450F is available in Kawasaki lime green, with new black alumite-coated rims for a factory
appearance, and aggressive graphics.
