How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a lightweight, nimble enduro for trail riding, green lanes, and playful off-road exploration rather than outright speed or long-distance travel.
- Built for
- A buzzy, high-strung two-stroke single that feels most alive when revved hard, delivering an eager, flickable, go-kart-like personality rather than sustained highway pull.
- Not ideal for
- Not a good match for riders wanting a comfortable long-distance tourer, a passenger-friendly bike, or strong stability and outright speed on paved roads.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
