I bought this seat pillion for my 09 Dyna from a forum member a couple years ago. I used it several times but now I have an Ultra and no need for it. This is the HD 52689-09 Detachable passenger pillion that mounts on the HD Luggage Rack 52796-09 and is detachable. It is the pillion on steroids. It is wider and has a welded luggage rack off the back. I have more pictures if you want them. Retail on the small pillion is $199.99. I am selling this one for $150 shipped.
