Designed with mid-level to expert riders in mind, the KX450 motorcycle has always been built with one goal in mind: to put riders on the top step of the podium. And for over 40 years KX brand motocrossers have been extremely successful at doing just that. To maintain its edge in this fiercely competitive class, the 2019 KX450 benefits from a new engine mounted in its leanest chassis to date, enabling it to turn even quicker lap times, and make it the most powerful machine in the paddock.

Complementing its already high performance, a number of new features – including finger-follower valve actuation, electric start and a hydraulic clutch, which are all firsts for a Kawasaki motocrosser – further elevate its race-winning potential.

ELECTRIC START

Being able to restart an engine quickly after a spill can mean the difference between keeping your lead, or having to fight your way back through the pack. Kawasaki’s first electric start on a motocrosser makes restarting the engine as easy as pushing a button.

EVEN MORE POWER

The new engine boasts an increase in peak power of approximately 2.5 kW (3.4 PS), while a flatter torque curve makes it easier to get on the gas. Finger-follower valve actuation (a valve train designed by Kawasaki’s MotoGP & World Superbike engineers) enables largerdiameter valves and more aggressive cams. Downdraftstyle intake and reduced friction loss (care of new plain bearings for the connecting rod big-end) further contribute to the power gains.

LIGHTWEIGHT ALUMINIUM PERIMETER FRAME

An evolution of the current design, the new frame features revised rigidity and includes the engine as a stressed member. A new swingarm also contributes to the revised rigidity balance and increased rear traction.

HYDRAULIC CLUTCH

Kawasaki’s first hydraulic clutch on a motocrosser offers more direct feel and lighter lever action. Less play as the clutch heats up during heavy use results in more consistent feeling.

HARD-HITTING FUEL-INJECTED 449CM3 LIQUID-COOLED, 4-STROKE SINGLE WITH FACTORY-RACER ENGINE TUNING

The new engine boasts an increase in peak power of approximately 2.5 kW (3.4 PS), while a flatter torque curve makes it easier to get on the gas.

Downdraft-style intake and reduced friction loss (care of new plain bearings for the connecting rod big-end) further contribute to the power gains.

STRONGER BRAKES

A larger-diameter ø250 mm rear disc complements the oversized ø270 mm front disc, delivering stronger stopping power. A new front brake master cylinder offers better initial control, while contributing to overall.
