So I'm looking at getting an aprilia because I've heard they are reliable, I love the looks and it's just something different than most people have. I'm a freshmen at the univ of utah and for my sophomore year I can get a new bike (well new to me, it might have to be used) so it won't be for awhile but I'm going to the aprilia/ducati dealership on saturday. I'm looking at the Tuono and the rsv, but what is the difference between the r version and the factory version of each? thanks
