Engine architecture
V-twin → V4 → Twin
The Tuono name has worn three different engine architectures. 2002-2010: V-twin (RSV1000 derived). 2011-current: V4 (RSV4 derived). 2021-current: Parallel twin (RS660 derived). Aprilia uses the Tuono badge on whatever middleweight or large naked they currently have.
Power range
105-175bhp
The Tuono 660 Factory makes 105bhp. The Tuono V4 makes 175bhp. Two completely different bikes wearing the same name. The 660 Factory is restrictable to 35kW for the A2 license; the V4 is a hyper-naked competing with the BMW S 1000 R.
What the Tuono invented
Naked superbike
The original Tuono 1000 R (2002) was essentially a naked RSV Mille. Aprilia stripped the fairings off their superbike and added high handlebars. Other manufacturers had done it before but Aprilia made it a category — what we now call hyper-naked.
Real cost change (660 vs 1000R)
−$3.2k
Tuono 1000 R was about $11,070 in 2006 ($18,630 today). The 2026 Tuono 660 Factory is $15,458 — about 17% cheaper in real terms, though the bikes are different (the 1000R was a litre-class hyper-naked, the 660 Factory is a middleweight with Öhlins suspension).
Why the 660 exists
A2 + cost
The Tuono V4 is a $24.3k+ premium hyper-naked. The Tuono 660 Factory is for riders who want Aprilia DNA at near-A2-license prices. Same engineering pedigree, different power, restrictable to 35kW for A2 licenses.
