How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's a purpose-built motocross weapon designed for closed-course racing and serious off-road trail riding, not general transportation.
- Built for
- Expect a razor-sharp, high-revving single-cylinder engine paired with premium WP suspension that rewards aggressive, athletic riding with incredible agility and feedback.
- Not ideal for
- This is a poor choice for commuters, passengers, long-distance tourers, or anyone wanting a comfortable, low-maintenance street-legal daily ride.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
