It is easy to peg the Aprilia Tuono 660 as simply the “naked version” of the fully faired Aprilia RS 660 sport bike, but the more and more I think about this Italian middleweight-twin, I feel that distinction is a misleading way to regarding the smaller Tuono.

The better way to think about the Aprilia Tuono 660 is to regard it as Aprilia’s road-focused 660 offering, whereas the RS 660 is geared more towards track enthusiasts.

As one can see, the Aprilia Tuono 660 doesn’t really have a lack of fairing, just more of a bikini approach, in contrast to the RS 660’s one-piece design.
