I feel like I'm the only person on the entire Internet that is comfortable on stock or near-stock BMW seats every time I read one of these threads!
I am another!
I might not be really fired up about the stock seat, but I don't dislike it enough to spend $1,000 or more to replace it. I have no issues running a 1,000 miles day.
I run a 2018 R1200RT and added Bead Riders as I like the air flow under my butt. I also ran Bead Riders on my Harleys.
