I have the 2015 RT-s oem backrest. It was easy enough to install. When I sat on the bike it pushed me out of the seat pocket. There is not any adjustments for this. I had to use shims on four of eight mounting points to get it back

Adding to that, my oem backrest would not allow a full szie passenger. The oem is solid and comfortable, but I have never had a backrest at this price point, $425 that did not adjust?
When touring, it has been critical for me to be able to make adjustemnts on the fly to change my sitting angles, [both forward and back ] thus increasing my saddle time.
Is there an adjusting backrest out there or is everything a fixed set point like my oem?
