How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for motocross racing and off-road riding, excelling on dirt tracks, jumps, and rough terrain rather than pavement use.
- Built for
- A high-strung, four-stroke single that rewards aggressive riding with sharp handling, strong mid-range punch, and razor-quick direction changes.
- Not ideal for
- Not suitable for commuting, touring, passengers, or riders seeking a comfortable, low-maintenance street-legal machine.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
