Rider Profile

Best ForThis is a serious off-road weapon best suited to intermediate through expert riders who already have dirt bike experience, not a first-ever motorcycle.
PurposeBuilt for cross-country and hard enduro-style off-road riding, with the durability and lighting/spark arrestor considerations typical of a closed-course and trail-legal race bike rather than street commuting.
Rider FitThe tall 37.7-inch seat height, 256-lb wet weight, and aggressive ergonomics demand good rider fitness, leg length, and confidence standing and shifting body weight on rough terrain.
CharacterIt has the raw, high-strung feel of a factory-style motocross-derived engine tuned for tractable power delivery over rocks, roots, and trails, rewarding an aggressive, active riding style.
Not Ideal ForThis is not the right choice for new riders, commuters, highway travel, two-up riding, or anyone wanting a comfortable, low-maintenance daily street bike.
