ChassisIrvine, CA (12/18/06) - Kawasaki has released new information and the final specifications on their hottest new race ready ATV, the KFX450R. From the factory, this new ATV comes equipped with a high-performance narrow aluminum frame and a power plant based on the highly acclaimed KX450F motocrosser. In addition to the KFX450R’s aluminum frame, it also features an aluminum sub-frame and swingarm which are made from the same lightweight aluminum as the frame.
Engine
The KFX450R’s power plant, based on the highly acclaimed engine of the KX450F motocrosser, was newly designed for use in an ATV racer. Adding fuel injection, an electric starter, fitting a reverse gear, lowering the centre of gravity by tilting the cylinder bank angle forward, re-tuning the engine for low-mid range torque to suit the weight of an ATV, and revising the intake and exhaust systems are among the many changes.

Chassis
A machine’s racing performance is often limited by the performance of its frame. And since swapping frames is no easy task, the KFX450R comes equipped with a high-performance frame right from the start.
The KFX450R is the first ATV in its class to offer a completely aluminum chassis: frame, sub-frame and swingarm are all formed from lightweight aluminum. But more than for its weight saving potential, aluminum was chosen for its highly rigid properties.
The highly rigid aluminum frame contributes to the KFX’s excellent rough-road handling and traction. The frame’s high rigidity (especially its torsional rigidity) makes the KFX extremely stable in corners and allows the suspension to be easily set up to suit course conditions.
