OEM Aprilia Cylinder Head Brace Kit for Tuono 660 - AF1-2B006263
The RS660 uses a pair of rear cylinder head bracing brackets that are not found on the Tuono, nor the Tuono Factory.
Complete fitment list at bottom of this page.
This kit is all the parts you'll need to add the RS660 bracing to your Tuono 660.
We're not sure what the function of this kit was, but Tuono 660 owners that intend to do serious track work may want to have this kit on their bikes.
Installation instructions are not provided, but installation requires a not insignificant amount of disassembly. Plan to remove both side fairings and be very comfortable with working blind: the inner braces install in a very tight space between the cyinder and frame. Level 10 patience is required.
