Rider Profile

Best ForThis is a full-blown motocross machine best suited to intermediate through expert off-road riders who already know how to manage a high-strung, clutch-dependent two-stroke-like power delivery from a modern 250cc four-stroke.
PurposeBuilt purely for closed-course motocross racing and aggressive off-road riding, not for transportation or general road use.
Rider FitIts light 109.2 kg wet weight and tall 955 mm seat height demand an active, standing riding style and reward riders with good fitness, leg strength, and confidence throwing the bike around.
CharacterSharp, flickable, and eager to change direction, with a stiff perimeter aluminum frame and race-tuned suspension geometry that favor jumps, berms, and rapid transitions over comfort.
Not Ideal ForThis is not the bike for commuting, highway travel, carrying a passenger, or riders wanting a plush, low-maintenance, easygoing ride.
