I don't have the Rivco, I have the Kury- Ergo II. Looking at your pic, it is very similar. They do stick out somewhat, but the Kurys will fold up, maybe the Rivco also does, when not in use, but they have to stick out a bit, or you wont get your legs around the lower fairing so to rest your feet. When mounted properly, they don't interfere with turning/leaning.
