Rider Profile

Best ForThis is a full-blown 250cc four-stroke motocross competition bike best suited to experienced or seriously committed intermediate riders, not beginners.
PurposeBuilt purely for closed-course motocross racing and off-road jumps, berms, and rough terrain rather than any form of street use.
Rider FitExtremely light at around 104 kg but demands strong physical fitness, aggressive body positioning, and clutch/throttle control since it has no electric start or road amenities.
CharacterA razor-sharp, high-revving racer's tool with premium suspension and a stiff aluminum frame that rewards precise, committed riding.
Not Ideal ForNot suitable for commuting, touring, carrying passengers, or any rider looking for comfort, low seat height, or road-legal equipment.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
