How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Designed for off-road trail riding, light enduro competition, and learning technical dirt riding skills rather than any road-focused use.
- Built for
- A lightweight, high-revving two-stroke enduro mini bike that rewards momentum, throttle discipline, and active body positioning over raw power.
- Not ideal for
- Not suitable for highway travel, long-distance touring, carrying a passenger, or riders seeking strong outright speed.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
