Rider Profile
| Best For | Best suited to newer or lighter riders who want a nimble, confidence-inspiring small-capacity supermotard for learning sharp handling and braking control. |
| Purpose | Designed as a light, flickable urban and backroad supermotard rather than a highway or long-distance machine. |
| Rider Fit | Its low dry weight and 900mm seat height make it approachable for shorter or less physically strong riders, though the tall supermotard stance still requires reasonable inseam and balance. |
| Character | Fun, playful and eager to be thrown into corners, with sharp steering geometry and a small tank that reward an energetic, city-and-canyon riding style. |
| Not Ideal For | Not a good fit for riders wanting sustained high speed, long motorway touring, passenger comfort, or serious off-road capability. |
