Rider Profile

Best ForBest for intermediate to expert off-road riders; the light two-stroke punch and tall seat suit those with real dirt skills, not first-timers.
PurposeA dedicated hard-enduro and trail weapon built for technical terrain, hill climbs, and woods riding rather than any pavement work.
Rider FitFeatherweight at 96.8kg dry with a lofty 950mm seat and 370mm clearance; roomy, upright, and demands a tall rider to touch down confidently.
CharacterRazor-light, flickable, and eager, the fuel-injected TPI two-stroke delivers a lively, revvy hit with almost no weight to hold it back.
Not Ideal ForNot for commuters, tourers, passengers, or anyone wanting comfort or highway pace; poor on paved roads and impractical for daily use.
