Rider Profile

Best ForThis is a competition-focused youth motocross bike intended for young, developing riders who already have solid off-road fundamentals, not beginners on their first bike.
PurposeBuilt purely for motocross racing and track training, with a peaky 2-stroke powerband and race-tuned suspension rather than any road or leisure use.
Rider FitIts low seat height, light overall feel, and compact chassis are tailored to smaller, lighter riders such as pre-teens and young teenagers progressing through the junior MX ranks.
CharacterSharp, lightweight, and eager to change direction, the 85 SX rewards aggressive throttle control and active riding with explosive acceleration typical of a small-bore 2-stroke.
Not Ideal ForIt is not suitable for adult riders, commuting, passengers, or anyone wanting a comfortable, road-legal, long-distance machine.
