Has anyone added one of these to their ST yet? I'm looking to get one of these soon but I wanted to get some expert opinions first. My wife would like to have a backrest and I'm not happy with the BRP option. If anyone has made this addition please post some photos and/or give any advise or opinions you may have concerning this item. I intend to install it myself. "gulp"
