How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a small-displacement enduro for off-road trails, tight woods riding, and learning fundamentals rather than any serious speed or distance work.
- Built for
- A playful, nimble little two-stroke enduro that rewards revving and momentum over outright power, with genuine off-road hardware like a perimeter frame, long-travel suspension and disc brakes.
- Not ideal for
- It is not for highway commuting, two-up touring, or any rider expecting real acceleration or sustained high-speed cruising.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
