I have owned and used the BF XL with backrest for 10+ years, and it works well. I installed it on a Suzuki M90, Kawasaki Concours and most recently on the F6b. Last month I purchased a Ultimate Seat with a driver backrest for the F6b. As such, I don't have to have the BF on the bike when doing short rides. I recommend the BF with backrest as an interim purchase.
