Electric Starting

An electric starter was regarded as essential in the design brief. A lightweight, highly reliable electric start system is employed for fast, easy, trouble-free starting. A manual kick starter is retained as a backup. Having both electric and kick starter means the bike can be quickly restarted if the engine stalls or has to be stopped.

Wide Ratio 5-Speed Transmission

The KLX450R’s gear ratios have been selected to specifically suit off-road competition. 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. Great, grippy footpegs are standard and ready to race.

Smooth Suspension

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. The high-performance race-spec KYB AOSS 48mm inverted front fork and superb rear suspension have been tuned for off-road competition and to minimise rider fatigue over long distances.

Powerful Disc Brakes

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.

Digital Instrumentation

Fully equipped for off road competition the KLX450R instrument panel lets the rider see what the bike is doing….right now.This lightweight digital instrumentation includes a speedometer, twin tripmeters, odometer and clock. Also fitted with a full completment of warning lights (not shown).
