How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's built primarily for trail riding, technical off-road terrain, and enduro-style adventures rather than pavement performance.
- Built for
- It has the light, nimble, and responsive character typical of a small-displacement single-cylinder enduro machine, prioritizing agility over outright power.
- Not ideal for
- This is not the right choice for riders wanting highway comfort, long-distance touring range, or a passenger-friendly setup.
