Rider Profile

Best ForThis is a full-blooded competition motocrosser best suited to experienced or intermediate off-road riders comfortable with a peaky 2-stroke powerband.
PurposeBuilt purely for motocross track riding and racing, not for street use or general transportation.
Rider FitThe tall 958 mm seat height, aggressive ergonomics, and physical demands of a light 2-stroke race bike require good rider fitness and reasonable inseam length.
CharacterSharp, explosive, and razor-agile, this bike rewards aggressive riding and precise throttle control with rapid acceleration bursts and flickable handling.
Not Ideal ForThis is not suitable for commuting, touring, carrying passengers, or riders seeking a comfortable, low-maintenance everyday motorcycle.
