I have considered a backrest for my '08 for a couple of weeks now. I've been thinking about getting a tail box with a built it backrest and mounting it to the front of the cargo rack, extending over the seat a bit. I'd have to be sure I could get my saddle bags under it (maybe use spacers) and I'd have to be able to get it off without too much trouble to get at the battery etc. BUT, it would give me a backrest, storage and hopefully leave a bit of the rack open at the back for tent, fishing rod holder etc. Looking for a good deal now, will post pics if I find one I like.
