I have a backrest that came with my 2015 RT S, and I like it. I have to remove it when my wife is riding, as she is short and can't get her leg up and over the seat with the backrest there. Also it gives us more room. As for my last ride, a 2000 Honda ST1100ABS, it did not have a backrest, but on long trips, I used a Kuryakan bag on the passenger seat to provide a backrest and was very thankful for it. As for me, Ilike it.
