I have no trouble at all on long or short trips with the standard seat without a back rest. If I spent the bucks for a Corbin anything I would doubtlessly love it too. I am 6'3" and 250 if you need that to judge for size. I have had cycle riders come up and look and sit on my seat and say it in the stock form is far superior to what they have. One guy at a car show yesterday asked if it was memory foam or similar stuff. Works just fine with me and like I always say it came with the bike. Bill
