Rider Profile

Best ForBest suited to intermediate-to-advanced off-road riders, as a small-bore two-stroke motocross machine demands active riding and precise clutch and throttle control to stay in its power band.
PurposeBuilt purely for motocross and cross-country racing on dirt tracks, not for street or commuting use.
Rider FitIts ultra-light dry weight and tall seat height favor smaller or lighter riders who can still comfortably manage the high seat and aggressive riding stance.
CharacterA high-strung, revvy two-stroke that rewards aggressive riding, quick gear changes, and an active body position with sharp, flickable handling.
Not Ideal ForNot suitable for riders wanting a comfortable, relaxed, road-going or touring motorcycle, or anyone seeking passenger capability or long-distance comfort.
