How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for cross-country and enduro-style racing, prioritizing light weight, high-revving power delivery, and serious suspension travel over comfort or practicality.
- Built for
- A raw, high-strung single-cylinder racer that rewards an active, aggressive riding style and punishes passive throttle input.
- Not ideal for
- This is not a good fit for new riders, commuters, or anyone wanting a comfortable, low-maintenance road-going machine.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
