How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Designed as a supermoto-styled commuter and fun urban runabout rather than a long-distance or high-speed machine.
- Built for
- A light, flickable, playful small-bore supermoto that rewards revving and aggressive cornering over raw straight-line speed.
- Not ideal for
- Not a good fit for riders wanting sustained highway speeds, long-range touring comfort, or serious two-up travel.
