Former MotoGP racer and current World Superbike rider Danillo Petrucci work with a fellow in Italy in creating two custom specials. One is called the Handy Man and was built starting with a Desert X.  But the real sweet one is the Modified V4 Panigale that has some 916 styling. I really like it and I like the exhaust tips.
