sorry, had some activation issues and the new years didn't help matters.
For the seat, any areas showing wear have been shown in the pics. The imprint in the front saddle is shown in the second pic, the piping wear on the rear is show in the third and fourth pic, and a minor rub is shown in the fifth pic. The hoop part for a back rest is just a small ring of leather in the rear of the rear saddle. I don't have the back rest, I believe it can be ordered from Corbin or maybe it's for a universal set up. I will take more pics of both saddles along with the hoop and post them up tomorrrow.
As for the windscreen I'm reading that several people have it on their 08/09's with no issue.
