How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Best suited for urban commuting, playful street riding, and light dual-sport style exploring rather than long-distance travel.
- Built for
- A quiet, torquey, clutchless supermoto that rewards flickable handling and instant low-RPM punch over outright top speed.
- Not ideal for
- Not a good fit for riders wanting long highway touring range, high top speed, 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.
