Rider Profile

Best ForThis is a serious competition-oriented enduro machine best suited to experienced off-road riders, not beginners, especially given its unique 2TRAC two-wheel-drive system which adds mechanical complexity.
PurposeBuilt for hardcore enduro and technical off-road competition, with the 2TRAC front-wheel-drive assist system designed to boost traction in slippery, rocky, and muddy terrain.
Rider FitThe tall seat height, minimal weight, and aggressive suspension travel demand good rider fitness, balance, and off-road skill to control the bike standing on the pegs over rough ground.
CharacterA light, high-performance liquid-cooled single with premium Ohlins suspension, race-bred DOHC five-valve architecture, and an innovative hydraulic front-drive system that sets it apart from standard WR450Fs.
Not Ideal ForNot a sensible choice for commuting, highway touring, carrying a passenger, or riders wanting low-maintenance, road-focused comfort.
