Rider Profile
| Best For | Suitable for newer riders as well as experienced ones seeking a light, characterful single-cylinder cafe racer for everyday fun. |

| Character | A charismatic, torquey single with cafe-racer styling that rewards revving it out and flicking it through corners. |
| Not Ideal For | Not ideal for riders wanting high-speed highway touring, pillion comfort, or any off-road capability. |
