Rider Profile

Best ForThis is a small-wheeled competition motocrosser built specifically for younger or smaller, developing riders, not adults or beginners to motorcycling in general.
PurposeDesigned purely for amateur motocross racing and off-road training on tracks scaled to junior riders.
Rider FitIts tiny 66 kg dry weight and low-for-motocross seat height suit lighter, smaller riders such as pre-teens and young teenagers rather than full-sized adults.
CharacterA high-strung, free-revving two-stroke that rewards aggressive clutch and throttle work with sharp, flickable handling on rough terrain.
Not Ideal ForThis is not suitable for adult commuting, highway travel, two-up riding, or anyone seeking comfort, storage, or long-distance capability.
