Rider Profile
| Best For | This bike suits riders with some experience who appreciate classic air-cooled four-cylinder character rather than outright modern performance. |
| Purpose | It's best suited to spirited weekend sport riding and backroad cruising rather than track days or long-distance touring. |
| Rider Fit | A moderate 203kg weight and modest power make it manageable for average-sized riders without excessive physical effort. |
| Character | The 654 Sport offers a nostalgic, mechanical riding experience with a smooth-revving in-line four and vintage sport styling. |
| Not Ideal For | It's not the right choice for riders seeking high top speeds, off-road capability, or serious long-haul touring comfort. |
