Conclusion - what gets stuck

You Aprilia Tuono 660 keeps what she promises. She is a sporty-racy naked bike with gaaaanz a lot of character. The price of 10,500 euros is somewhat ambitious, especially compared to the sister RS 660, where the QuickShifter is in series production. Despite the surcharge of 219 Euro on this bike we would definitely recommend the QuickShifter, because it fits a) to this bike and because b) the 6-speed gearbox is a bit boney and hooky.
 
The Tuono doesn't leave you cold, it's not perfect and that's a good thing. Each ride becomes an experience and design as well as volume let a Tuono biker stand out from the crowd - bike!

The test bike was provided to us by Zweirad-Technik-Schielmann in Bokel - thank you very much.
