How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for playful, flickable fun on tight city streets and supermoto-style circuits rather than outright speed or distance.
- Built for
- A high-revving two-stroke minimoto with sharp, go-kart-like handling and an eager, buzzy character that rewards aggressive cornering lines.
- Not ideal for
- Not for riders wanting real highway speed, long-distance comfort, or a passenger-friendly machine.
