which is comfortable for just sitting there, but makes it more difficult to stay "on top of the bike", or to keep my weight forward enough for handling the bike as precisely on the curvy roads. So I use the stock SM-R seat more.
Try one right after the other IN THE CURVES and see if you can feel the difference.
This is probably a dumb question, but do you know if the R seat fits on the SMT? My SMT seat pushes me too far forward.
