Bought a 2021 F900R in mid-March. Enjoying the bike very much except...my 70-something butt is very uncomfortable after about 1 hour on the road. I'm strongly considering the Sargent seat: it's fairly priced (with the Rally discount), and Sargent offers a 30-day full refund if I'm not satisfied. It almost seems that there's no great risk here. Any thoughts are much appreciated. Jim, Chicago
