Rider Profile

Best ForThis is a serious enduro machine best suited to intermediate to expert off-road riders comfortable with a peaky two-stroke and tall, minimal seat.
PurposeBuilt purely for technical off-road enduro riding, trials-like terrain, and competition rather than street use.
Rider FitThe featherweight 101 kg dry chassis and tall 945 mm seat height demand good rider fitness and reasonably long legs to manage standing riding and technical sections.
CharacterA raw, aggressive two-stroke enduro bike that rewards active riding with explosive power delivery and razor-sharp handling in the dirt.
Not Ideal ForThis is not the bike for commuting, highway touring, carrying a passenger, or riders wanting a comfortable, low-maintenance ride.

Character map is an editorial estimate based on this bike's specifications, not a lab-tested measurement.
