Now this is a machine I like for various reasons.

First it is beautiful (to my taste anyway), made by a small (yet successful) company which gave itself the strength to kick the HRC's ass around the tracks  in 125 and 250 GP racing.
This is a V-twin, set at 60 degree, with a very typical noise (different from the Ducati's).
Aprilia delayed the release of that bike for months, and many people went on about the fact that Aprilia couldn't make a 4 stroke bike to save their lives. Now the bike is out a couple of years, NO KNOWN ISSUES have arised and the bike has been very reliable since day one (except for few models which were recalled for a faulty rear wheel shaft)
Nice performance considering that even R1's were recalled for a faulty rear sprocket !!!
