How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for trail riding, enduro competition, and technical off-road terrain rather than pavement or long-distance travel.
- Built for
- A lightweight, high-revving single-cylinder enduro bike that rewards aggressive, standing-up riding with sharp handling and strong suspension travel.
- Not ideal for
- Not a good fit for riders wanting a comfortable street commuter, a passenger-friendly bike, or a machine suited to sustained highway touring.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
