The 2008 Kawasaki KX is a series of motocross bikes that range from the Kawasaki KX65 and KX85 youth motocross bikes to the four-stroke engine Kawasaki 250F and 450F bikes. With the unveiling of the 2008 model lineup, the Kawasaki 250F and 450F bikes have been updated, while the KX65, KX85, KX100 remain unchanged from the 2007 models.
The 2008 Kawasaki KX65 is the entry-level mini-motocross bike offered by Kawasaki for those young riders who want to enter the motocross ring. The high-performance two-stroke engine provides plenty of power for those riders who are looking to learn the skills of motocross riding on the track. The engine is coupled with a six-speed transmission and automatic clutch to ease the rider into learning to control the bike over the demanding motocross course.
As a rider grows, both in skill and size, the next step is the 2008 Kawasaki KX85. The 84cc engine provides that much more power, and is also equipped with plenty of high-end technologies. This bike was designed for riders of varying skill levels and is equipped with a six-speed transmission, the Kawasaki integrated power-valve system, and a tuned exhaust pipe.
The 2008 Kawasaki KX100 was designed to provide a link between those riders who have outgrown the mini-motocross ranks, but may not be ready for a full motocross bike. As well as having a larger, more powerful two-stroke engine, the KX100 is equipped with larger wheels and tires and a high-tensile steel frame with a low center of gravity to provide an appropriately sized bike for teens. The goal of the design was to allow more skillful riders to continue to focus on skill improvement, without having to worry about controlling too much power.
The 2008 Kawasaki KX250F sees a host of refinements for the launch of the new model year. The engine remains the same as found in the 2007 model, with the redesign of the crankcase, shift lever, and suspension leading to improved shifting, better reliability, and improved handling of the KX250F motocross bike. The adjustments to the rear shock give the rider a slightly higher ride height, so handling is quicker and the overall ride has a more aggressive feel.
The improvements to the 2008 Kawasaki KX450F mean that the motocross bike is easier to ride and handle, and more reliable. The changes made to the engine resulted in reduced vibration and better low rpm performance, which meant that rider fatigue is reduced, and riders can travel faster for more laps. Reliability of the engine was also improved with the refinements made to its components. Changes to the chassis and suspension lead to quicker turning and overall better handling of the KX450F.
