Rider Profile

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