I have tried almost every seat for the Harley touring. I’ve had the Harley Sundowner, Harley Hammock, stock seat mod by Mean City. I just can’t seem to get more than 150 miles before I get sore. We currently have a 2021 Triglide with a Mustang Summit seat. It’s prob the best I’ve had but it’s still not “there”. The only two seats I havent really tried are Ultimate or Corbin. I did have an old Corbin on my first 2006 Harley that was used that we tried but it was just too hard. Although I only ride that seat for couple hundred miles and I have heard they take long time to break in. Oh and I forgot we have not tried the Road Zepplin seat. So I guess I’m looking for opinions on the three seats Corbin, Ultimate, and RZ.
