The high-powered, lightweight 4-stroke engine is derived from the Championship Winning KX450F and features several tweaks including increased flywheel mass for greater low-end torque.

Featuring dual overhead camshafts lifting lightweight titanium valves with dual progressive valve springs, the KLX's head boasts revised cam lift and timing to boost low and mid range torque.

A lightweight, highly reliable electric start system is employed for fast, easy, trouble-free starting. A manual kick starter is retained as a backup.

The MX inspired aluminium chassis features centralised gravity and inertia points to deliver incredible traction, light handling and confidence inspiring high speed stability

The KLX450R's gear ratios have been selected to specifically suit off-road competition. Likewise, the engine is tuned for a broad delivery of power to optimize the gear ratios. The gear sets and center cases are very compact allowing the frame to be narrower at the rider‘s ankles.

Kayaba twin chamber forks take care of the big hits up front while Kawasaki's legendary Uni-Trak rear suspension gets the power to the ground. Fully adjustable damping at both ends provides easy tuning and setup.

Petal brake discs front and rear reduce unsprung weight, and help clean the brake
pads for more efficient braking. The forged aluminium rear brake pedal has a heavy duty mounting bolt and a large “foot” with sharp teeth to provide a solid feel. An integrated rear brake fluid reservoir provides increased reliability.

Fully equipped for off road competition, the KLX boasts a fully featured instrument panel including speedometer, odometer, twin trip meters and a clock.
