I have the GL 1800 Seat with Driver Backrest, Passenger Backrest with Full Dark Red Inlays on my 2012 Wing and it just looks so great. I have made over 80 000km since I got the seat and I am really very happy to have made the change.
I have one on my Road Glide Ultra. Been on there awhile now. Best seat ever. The seat is actually a little longer than OEM and much better padding - which makes it only slightly more difficult to secure on my bike because of the tour pak. Other than that - fantastic seat.
