Rider Profile
| Best For | Best suited to younger or novice riders, often on a learner license, who are building skill in a lightweight, low-powered supermoto package. |
| Purpose | Designed for playful, nimble city riding and light supermoto-style fun rather than any serious speed or distance work. |
| Rider Fit | Its tall 870mm seat height and 85kg dry weight favor a rider comfortable balancing a tall, flickable bike but who doesn't need much muscle to manage it at a stop. |
| Character | A tiny, high-revving two-stroke supermoto that rewards eager throttle use and sharp cornering lines over outright pace. |
| Not Ideal For | Not a fit for riders wanting highway speed, long-distance touring capability, or a passenger-friendly setup. |
