First:
Here in FL the semis will run you down if you're strolling along at anything less that about 80 so I'll skip right past "how fast have you gone" type stuff. That said...
Next:
Sorry, not the newer RK, but with roughly 550-600 lbs aboard total (including us), my '07 FLHR never even whimpered unless there were some damn gusting cross-winds like going across a causeway on a blustery day.
Finally:
Recent experience is RG, not my 30,000 mile old RK, but the frame improvement is quite noticeable to me. Therefore I'm betting a good rider would do VERY well indeed with a new FLHR.
