Fitment - RSV4 09-20, Tuono V4 11-20
Genuine Aprilia motorcycle item, number 856543, part number 28 in the diagram.
The coolant manifold provides a localised connection point for coolant lines when installing multiple heat exchangers as it's an easier and more secure way of plumbing. These can occasionally fail and leak due to corrosion in caustic environments.
As this is a genuine item, it will be a direct replacement for your damaged or broken one.
