Hi all.. I ride a 2016 F3 Limited. Started with the stock seat. Could go about an hour and had to stop to walk around. Went with the comfort seat from BRP. Much better but not great. Ordered the Airhawk Cruiser R (large) seat cushion. Think this might be the answer after I get the air pressure just right. First ride was a little over 2 hours. No pain!! Inexpensive option to a custom seat. FYI.. I am 6.3 and 190 lbs.
