Rider Profile

Best ForThis is a competition-focused motocross machine best suited to experienced off-road riders comfortable with a tall, aggressive, race-oriented setup.
PurposeBuilt purely for motocross tracks and rough off-road terrain, not as a road-legal or all-purpose machine.
Rider FitThe tall 960mm seat height, kick starter, and light 108kg dry weight demand good physical fitness, leg length, and confidence standing on the pegs.
CharacterA raw, high-strung single-cylinder motocrosser with sharp throttle response, minimal weight, and razor-sharp handling for jumps and berms.
Not Ideal ForThis bike is not for commuting, touring, carrying a passenger, or riders seeking comfort and low-effort ergonomics.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary).
