The WR450F of this period is a fuel-injected enduro bike with a 449 cc five-valve engine, built on a compact aluminium frame and suspension derived from the YZ250F. It was pitched as an easy-to-ride, versatile off-roader with a digital enduro computer and a fully adjustable KYB rear shock. Press tests praised its smooth, tractable power but noted its weight.
