I saw you posted the same question on the Italian forum.
Technically speaking it's feasible.
You would need new spacers, a new collar (both can be machined without too much hassle) and new bearings (industrial supply shops are your best friends).
Not so sure about brake discs, though they are the same size as OE ones.
So if you have time and money or good workshop skills and the asking price for the Aprilia wheels is really good I would say why not?
you can fit them when you do like DesperateSP2 instruct you.
Looks well but not not easier to handle than SP2 oem wheels.
Take mag oder carbon wheels and you want else.
