2016–2018 race electronics
GenerationThe late KX450F combines its 449cc single with launch-control and mapping options for the motocross track. Inspect clutch, brakes and original electronics; hard race use shows up there quickly.

About this model
About the Kawasaki KX 450
The Kawasaki KX450 is a motocross competition bike built around a 449 cc four-stroke single-cylinder engine. Kawasaki introduced the KX450F (later renamed KX450) in 2006 as a four-stroke answer to the dominant Honda CRF450R. Over the years the KX450 evolved into one of the most technically refined bikes in its class, with electric start (from 2019), launch control, and traction control standard on later models.
The KX450 targets experienced motocross riders competing on official motocross tracks. The engine is tuned for maximum performance, not road comfort, it is not road-legal. Not a beginner's choice; the power and sharp calibration require riding skill. Rivals are the Honda CRF450R, Yamaha YZ450F, and KTM 450 SX-F.

Before you buy
What to check before buying
- Check valve clearances and cam lobes; 450 cc motocross engines require frequent valve adjustment (every 15–20 riding hours).
- Inspect crankshaft and connecting rod for wear on high-cycle competition engines; worn crank causes vibration and power loss.
- Check the fork and monoshock condition; poorly maintained suspension is a safety hazard on track.
- Verify engine hour meter readings match actual wear; motocross engines run harder per hour than road bikes.
