How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for cross-country and hard enduro-style off-road riding, with the durability and lighting/spark arrestor considerations typical of a closed-course and trail-legal race bike rather than street commuting.
- Built for
- It has the raw, high-strung feel of a factory-style motocross-derived engine tuned for tractable power delivery over rocks, roots, and trails, rewarding an aggressive, active riding style.
- Not ideal for
- This is not the right choice for new riders, commuters, highway travel, two-up riding, or anyone wanting a comfortable, low-maintenance daily street bike.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
