I'm a little confused by your post. Did you mean a backrest for the driver? If so, Harley makes an adjustable rider backrest that has I believe a 30% adjustment forward to back. I have it on my Ultra and it works great because I can tilt it forward and up if I need or want. It's a little pricey but it's the best money I've spent on my bike in a long time. The non adustable backrest did not work as it was too far back. This one you can adjust it to your liking.
