Please excuse me if there is already a topic on this. Has anyone tried this seat yet? I looked at one at my local dealer and it looks like it would be pretty nice. It has a removable rider backrest on it that is fully adjustable. The passenger pillion on the stock 2013 Heritage kills my lower back after a hundred miles or so cause I start slouching and it pokes me right in the lower back. Any help would be appreciated. Thanks.
