I've ridden 20something mph on the HD, & my former S200 as well as 50mpgish gusts with steady 30ish on the 650.
It can be done, & really the 20something wasn't heinous.
Slowing down helps a lot, and leaning into it of course, but you do have to be on point and need to keep away from other vehicles as much as you can so you have the room to maneuver, sometimes not intentionally. The gusting was really the hardest part in my experience, that & the rain and potential for hydroplaning that tends to come along with those.
