I really liked the R and the naked look. It has a ton of torque and handles very well... it was a lot of fun to ride. The R, under 9K RPMs, I feel it pulls harder than my 2020 RR. The 2020 RR is really restricted in 2nd and 3rd gears in the USA due to EPA regulations (well documented at BrenTuning and an RR forum). I had no mechanical issues with the bike at all... though I only put 5K miles on it. I put just over 5K in 3 months on the RR also and so far no issues.
My only complaint about the R were the handlebar and footpeg vibrations. I added heavy bar ends that "fixed" the tingling in my hands. I ruined the camera on 3 iphones due to handlebar vibrations and using a Rokform mount. Rockform would send me something new to try, but after 3 failures I stopped trying. Lucky, Apple repair each time for free as a mechanical failure. For the footpeg vibrations I think my right foot must be sensitive... I experience similar footpeg vibrations on the RR but not quite as much. After awhile I did add a little bigger wind screen on the R that made a big difference.
On weekends, I could ride the R for a hours comfortably from a seating position - the seat itself and the vibration issue were the cause of discomfort... I would have done a seat mod/replacement if I keep the bike longer. Other than bike protection mods, I wasn't planning on doing anything else. After I went to CSS in May of this year and rode the RR, I knew I wanted one. CSS at the time had one 2020 RR but students couldn't ride it. I couldn't afford 2 bikes at the time so had to trade the R in. I'm 53 and on the RR, my knees do start to hurt after a few hours of riding where that did not happen on the R. Always, when I get tire on the RR, I do notice putting more weight on my wrists if get lazy with gripping the tank with my legs. On the R, I never had an issue with weight on the wrists when I started getting tired.
