Best for
Designed as a lightweight two-stroke enduro for trail riding, learning off-road skills, and casual commuting rather than outright speed.
Built for
A playful, buzzy little two-stroke that loves being thrown around trails and tight corners but runs out of breath on the open road.
Not ideal for
Not for riders wanting sustained highway speeds, long-distance touring comfort, or a passenger-friendly ride.

Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
