This is an interesting thread. I have a 2020 F750GS with the standard seat and find it very comfortable. I can ride hundreds of miles with no discomfort at all. Although the bike came with a standard seat, I recently purchased the low seat to get my feet closer to the ground. I can still ride for hundreds of miles without any discomfort. Granted, all of my riding is on the tarmac. I do not go off-roading.
Not to brag, but my wife is always telling me what a nice bum I have so maybe that has something to do with it? Having a meaty bum
When I say "meaty", I am only 170 pounds so it's not a fat bum, but rather a firm one. I should also note that I have lower back issues which flairs up from time to time, but never when riding on my Beemer.
So are most of the riders here complaining about comfort, talking about their on-road, or off-road experience? Every time I get on my bike it just feels so comfortable it's hard for me to comprehend these particular bikes being uncomfortable. Perhaps when posting we can put our height, weight, and inseam to see if there is a trend? I totally get the people with "boney" bums having comfort issues, but i'd imagine that would be on any bike.
