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.
