NEW swingarm with revised rigidity to match the main frameKawasaki’s engineering team has worked closely with the factory racing teams to develop an industry-leading slim aluminum perimeter frame that is capable of providing precise cornering through excellent front-end feel and the ultimate agility at high speeds.

Revisions have been made to the shift drum and shift fork, resulting in a weight savings. While the base settings on the KX450 motorcycle are based on extensive testing and racing, the motorcycle provides a huge range of technology and adjustment to help ensure every rider can experience the incredible ability of this extremely capable motocross bike.

Derived from Kawasaki’s factory racing efforts, front-end traction has been improved thanks to a new larger- diameter 22 mm front axle shaft. Engine covers were designed to be smooth in order to not impede rider movement.

The lightweight bridged-box piston uses the same design as the Monster Energy Kawasaki race team’s factory race bikes, contributing to strong performance throughout the entire rpm range. The four-pin DFI couplers select maps that are designed for standard, hard or soft terrain settings.
