Rider Profile

Best For	This is a full-on competition motocross machine best suited to experienced off-road riders and racers, not beginners.
Purpose	Built purely for motocross racing, it excels at jumps, berms, and rough closed-course terrain rather than any form of street use.
Rider Fit	The tall 925mm seat height, lightweight 106kg dry chassis, and aggressive four-stroke power delivery demand strong rider fitness and confidence standing on the pegs.
Character	Sharp, explosive, and razor-focused, this bike rewards aggressive inputs with rapid direction changes and strong acceleration out of corners.
Not Ideal For	This is not suitable for commuting, touring, carrying a passenger, or any rider seeking comfort and low-maintenance road use.
