Yes it's called a rear seat cowl (here in the U.S. anyway) The dealer I got my bike from ordered me one, but it won't be in for a few weeks. And F.Y.I. the bike won't actually be a mono-post, it's just a cover that looks like this picture that Revol posted. There are bikes that are either mono-post or bi-post, you can't carry a passenger on a true mono-post as the sub-frame isn't strong enough to carry a passenger. My buddy has a Ducati 999 that is a mono-post, and the rear part of the frame is lighter, but not strong enough for a passenger.
