Rider Profile

Best ForThis is a demanding, race-bred enduro machine best suited to intermediate and expert off-road riders comfortable with a light, punchy two-stroke.
PurposeBuilt for competitive enduro riding and technical trail work, with Six-Days spec parts signaling serious off-road racing intent rather than casual use.
Rider FitThe tall 940mm seat height and 101kg dry weight make it agile once moving but demanding of rider fitness, leg length, and confidence at low speed.
CharacterA sharp, aggressive two-stroke enduro bike with premium suspension components that rewards an active, attacking riding style over rough terrain.
Not Ideal ForThis is not the right bike for new riders, commuters, passengers, or anyone seeking a comfortable, road-oriented touring experience.
