How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a nimble, urban-friendly supermoto for weaving through traffic, flicking around back roads, and having fun rather than covering long distances quickly.
- Built for
- A cheeky, playful little street bike with sharp steering geometry and supermoto styling that rewards revving it hard and throwing it into corners.
- Not ideal for
- Not for riders wanting sustained highway speed, long-distance touring comfort, or serious off-road capability given its road-biased 17 inch wheels and modest 125cc output.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
