How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for motocross racing and track training, with a peaky 2-stroke powerband and race-tuned suspension rather than any road or leisure use.
- Built for
- Sharp, 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 for
- It is not suitable for adult riders, commuting, passengers, or anyone wanting a comfortable, road-legal, long-distance machine.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
