The seat is quite firm and smooth, so you will slide back at 60+ mph (the hump is too far back to help in this regard). Of course, this is an issue with any bike without any wind protection. It works, however, and is one of the best looking aftermarket seats IMHO. I'd really like to find an exact 750 MkIV Roadster replica with the 16 pleats and strap, but I have searched high and low and they seem nowhere to be found.
