Kawasaki engineers have combined revisions in cam lift and timing in order to boost low and mid-range torque. Adding to the special characteristics of this engine are a heavier flywheel with double the mass of the KX450F’s unit and a wide-ratio five-speed transmission with gears that have been specifically selected for off-road competition.
The Kayaba AOS inverted fork provides superb damping and steering precision with tuning specifically optimized for light, easy handling characteristics. Oil and air are kept in separate chambers for stable damping performance during long events and low-friction seals contribute to smooth fork action.
The KLX450R’s chassis has been specially set-up to be nimble while negotiating narrow trails or maneuvering between rocks and trees.
:shock:In fact, a fully-equipped KLX450R only weighs about 22 pounds more than the KX450F.
