Rider Profile

Best ForThis is a purpose-built children's motocross machine designed for young, developing riders progressing through junior competition ranks, not for adults or beginners of any age.
PurposeBuilt exclusively for motocross and off-road track racing to teach real race craft on a scaled-down, competition-grade two-stroke.
Rider FitIts tiny 53.5 kg dry weight, low 730 mm seat height, and light clutch and controls are tailored to a child's small stature and limited strength.
CharacterA snappy, high-revving two-stroke with a six-speed gearbox that rewards clutch and throttle skill, encouraging aggressive, race-focused riding.
Not Ideal ForThis is not suitable for adult riders, commuting, touring, passengers, or anyone seeking road-legal or long-distance capability.
