Having found the stock seat on my 2018 RTL to be less then comfy I thought I'd take a run at the Air Hawk Cruiser Large seat. Well after following the instructions to a tee, I found the seat to really be no better then the stock one I have. At least for me that is. So I'll be sending it back. I might give the Ultimate seat a closer examination to see if perhaps it doesn't fit my needs. But that is a pretty big cash lay out if it's doesn't work either.
