The thing that i find unusual about that is what does Rossi have to do with Ducati? Is that a mock up or have they made the bike?
It's a concept sketch, doesn't need exhausts Ducati VR|46 Concept by Steven Galpin - Asphalt & Rubber (it's in the swingarm)
Looks nice. I was expecting it to be dayglo and stickers as usual (which looks like ass) but this has some style. Nice concept.
