I had my wife in my gt, cherohala from Robbinsville to tellico with stop in the falls, and while that count for a few hours riding, she can complain for a lot longer about the seat....
... saying so, I had my sister, I have to say a bit overweight and we rode about 7 hours for 3 or 4 days around the smokies, 40f, and that was in my old cbr1000rr... no major complains outside of having to thaw her to be able to get out the bike... the last day there, for a change, we went e to the underground sea attraction instead. ...
So,.. it's not just the seat, a lot have to do with expectation and interest.
I remember once in Westchester, NY. Went for a ride with my wife, I had a Yamaha warrior then, when we stop in the dunkin donuts to grab a coffee and meet the group, she was like, now we get back right? Lol... we went all the way to Albany that day and back....
