Tuono 660
Aprilia's Tuono 660 deploys the RS 660's 659cc parallel-twin in a naked chassis — 95 hp with cornering ABS and traction control in a 403-lb package at $7,000–$9,000 used, making it the most electronically sophisticated option in the middleweight naked class at this price. The Aprilia dealer network is sparser than Japanese brands; confirm a nearby dealer before committing.
