Rider Profile

Best ForBest suited to intermediate through expert riders who already have off-road or motocross fundamentals, as this is a purpose-built race bike, not a beginner machine.
PurposeDesigned purely for motocross and off-road track competition, prioritizing light weight, sharp handling, and high-rev four-stroke power delivery over any road-going comfort or practicality.
Rider FitTall seat height, minimal suspension give at rest, and a firm, aggressive riding stance demand good rider fitness, strength, and confidence standing on the pegs.
CharacterA raw, focused competition tool that rewards active, aggressive riding input with explosive acceleration out of corners and razor-sharp direction changes.
Not Ideal ForNot for commuters, passengers, long-distance touring riders, or anyone seeking a comfortable, low-maintenance street-legal machine.
