Aprilia

RS 660

Aprilia's RS 660 extends RSV4-derived APRC electronics — cornering ABS, traction control, wheelie control — to a 100 hp parallel-twin sportbike at 403 lb, filling the mid-size sportbike slot between the Ninja 500 and full litre-class. The sparse dealer network is the one recurring ownership concern; buyers outside major metros should verify service access before purchasing.
