- Built primarily for serious enduro and technical off-road riding, with road-legal status intended mainly for connecting trails rather than for street-focused use.
- Built for
- It has the character of a raw, torquey open-class enduro weapon, favoring aggressive, direct rider input over smoothness or refinement.
- Not ideal for
- This is not the right bike for new riders, commuters seeking comfort, or anyone wanting a smooth, plush machine for long paved touring or carrying a passenger.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
