Rider Profile

Best ForThis tiny-capacity two-stroke enduro is best suited to younger or novice off-road riders, or experienced riders looking for a lightweight play bike rather than raw performance.
PurposeIt's built for off-road trails, motocross-style practice, and learning enduro skills rather than any road-going or touring use.
Rider FitIts very low dry weight and small frame make it extremely easy to manhandle, pick up, and throw around, ideal for lighter or smaller-statured riders.
CharacterA nimble, buzzy little two-stroke that rewards revving and playful riding rather than outright straight-line speed.
Not Ideal ForIt's not for riders wanting highway capability, long-distance comfort, or carrying a passenger.
