Eager to learn - No RSV...yet

Aug 2018
Indianapolis, IN, USA
Greetings, all! I am a Aprilia newb, and I wan to learn about the RSV Mille, particularly the R. I have my eye on an 07, and want to know what I should look at/for, and if there was such a thing as a special SP (homologation) version in '07. I have read conflicting stories. I even called a local dealer, to which they responded I don't know. I don't even know what to ask. I have seen Apes before, and I do enjoy them, but am definitely a newb
