The Tuono 660 is essentially a naked RS and it takes a similar route as the larger Tuono takes with the RSV4. In typical fashion, the aggressive looking sport-naked puts a lot more of its mechanical bits on display, but it still sports a flowing design. As is the case with any modern-day performance Aprilia, the Tuono 660 will also feature comprehensive electronic rider aids. Called the Aprilia Performance Ride Control (APRC), the six-axis IMU based system includes three level cornering ABS, adjustable wheelie control, traction control and engine brake control. It also gets an up/down quickshifter and cruise control. The motorcycle has five ride modes - Commute, Dynamic, Individual, Challenge and Time Attack. These modes can be accessed via the TFT dashboard.
