Rider Profile

Best ForThis is a serious enduro machine best suited to intermediate-to-advanced off-road riders comfortable with a punchy two-stroke powerband.
PurposeBuilt purely for competitive and recreational off-road enduro riding on trails, woods, and technical terrain rather than road use.
Rider FitIts very low dry weight around 101 kg and tall 940 mm seat height demand an active riding style and decent rider fitness and leg length.
CharacterA light, aggressive, high-revving two-stroke enduro bike with premium long-travel suspension that rewards precise, energetic riding.
Not Ideal ForThis is not a good fit for riders wanting a comfortable daily commuter, a passenger-friendly bike, or long-distance paved touring.
