According to my Indy who does a lot of performance builds, one issue that has surfaced lately is that Harley had installed a batch of 114 cranks with excessive run out. However, it would only come into play if you wanted to do engine work. If you leave the motor stock, this probably would not be a problem.
I did 4000 miles on my 23 Road King with no issues, but when I went to do a big bore I needed a new crank because the stock one was out of spec. That was $2K I wasn't planning on spending.

I had about 18K miles on my 2018 RGS with a 107. No huge issues, but it was noted in a service at around 15K miles that the transmission fluid was low, but they never measured the engine oil to see if it was transferring.
When I brought it up to the techs, and the TSB about the transmission breather, he printed up an estimate on how much it would cost me to have done. I told him there was a TSB, and that it was noted in my service. They weren't going to cover it because there was no evidence of sumping.
I kept an eye on the fluids and eventually traded it anyway.
The 121 has been great so far, about 3K miles. Some cruising 2-up and some hauling @$$ with no passenger.
Off topic, but the one issue I have so far is that there's no aftermarket cams available for the VVT engine. I've pinged a few companies who mentioned that no one would release one until tuning and testing have been done, which is a given. So maybe some are in the works.

Sumping and transmission oil transfer to the primary are 2 different, not related issues.
