Rider Profile
| Best For | Best suited to riders with some experience who appreciate a characterful boxer engine and shaft-drive quirks over outright sportbike performance. |
| Purpose | A muscular, style-focused naked bike meant for spirited street riding and weekend backroad blasts rather than track days or long-haul touring. |
| Rider Fit | The tall 835mm seat height and 239kg wet weight demand reasonable rider height and confidence at low speed, though the wide bars keep steering effort manageable. |
| Character | Torquey, distinctive, and mechanically charismatic, with the boxer's low-end pull and shaft drive giving it a relaxed, unmistakable personality rather than razor-sharp aggression. |
| Not Ideal For | Not a good fit for riders seeking off-road capability, a passenger-friendly plush tourer, or cutting-edge outright acceleration. |
