easy to install, saves your A#@ (backside)
I got the two piece with the driver back rest. It goes on just in just a couple of minutes. As far as comfort? Well, this may sound like I have stock in the company but, the first day I put it on I took the bike out and put 400 miles on it and I felt great. There is no way I would have done that on the original seat. I would have had a numb rear end long before. Along with the Driver back seat, foot pegs, and the throttle master it was like sitting in a easy chair (almost). Best investment to comfort on my bike to date.
