Rider Profile
| Best For | Friendly and predictable enough for newer riders moving up, yet has enough punch and a characterful triple engine to keep experienced riders engaged. |
| Purpose | Designed as a versatile everyday roadster that excels at commuting, weekend blasts, and learning to ride briskly rather than as a dedicated track or long-distance tool. |
| Rider Fit | A low seat height and modest 195kg wet weight make it approachable and manageable for riders of varying heights and confidence levels. |
| Character | The 660cc triple delivers a smooth, torquey, and vocal power delivery that feels lively without being intimidating. |
| Not Ideal For | Not the ideal choice for riders wanting serious off-road capability, high-speed track dominance, or dedicated two-up long-haul touring comfort. |
