Rider Profile
| Best For | Best suited to intermediate or experienced riders who enjoy a light, flickable single that rewards aggressive throttle and brake inputs. |
| Purpose | Built for sharp cornering, tight twisty roads, and urban blasts rather than long-distance travel or off-road work despite its dual-sport-derived chassis. |
| Rider Fit | The tall 875mm seat height and narrow, upright ergonomics suit taller or more confident riders comfortable with a bike that feels lanky at a standstill. |
| Character | A punchy, torquey single-cylinder supermoto that trades outright top speed for razor-sharp handling and playful, wheelie-friendly character. |
| Not Ideal For | Not a good fit for riders seeking touring comfort, pillion-friendly ergonomics, or serious off-road capability. |
