Rider Profile

Best ForThis is a competition-bred enduro machine best suited to riders with solid off-road experience, not newcomers to dirt bikes.
PurposeBuilt for serious enduro racing and technical trail riding, with Six Days-spec parts aimed at hardcore competitive use.
Rider FitIts tall seat height, minimal padding, and 111 kg dry weight demand good fitness, strong legs, and confidence standing on the pegs.
CharacterA light, razor-sharp, high-revving single that rewards aggressive, active riding and punishes hesitation on rough terrain.
Not Ideal ForNot suited to riders wanting a comfortable commuter, a passenger-friendly machine, or long paved highway touring.
