I find that relaxing a bit helps in crosswinds. That sounds illogical, however, I find that loosening up a bit on the death grip and focus on "herding" the bike helps. It won't keep it from being blown around, but once I get it in my head the bike isn't going to go tumbling like a tumble weed and focus on just keeping it on the black stuff, it goes better. Similar to learning to ride on gravel and dirt. Many at first tend to "tighten up", hoping to gain some control, and in reality, are hindering operation. I have far more miles on heavier motorcycles, that are not prone to "giving to the wind", which makes it a little unnerving sometimes. Especially when trying to hang with larger, heavier motorcycles out on the road. I have ridden in a wind storm that was so bad I stopped and removed the front fender, as I was certain the front end was being lifted off the asphalt on occasion.
Riding with other type bikes presents problems sometimes, as those bikes may handle the wind better than the tall, top heavy, high fendered KLR 650. On the flip side, you can see and travel three times more of the Black Hills on a KLR than the street bikes can.
My last suggestion would be to slow down, unless you are evading a jealous husband. There are few places I need to get to anymore that I can't get to at 50 MPH. While I agree 80 MPH would be nicer, I prefer to get there in one piece, and have some kind of enjoyable ride behind me, rather than a hard core fight against the wind. Like a sailboat, sometimes we have to adjust to the wind. If that does not fit in your plans, you may have chosen the wrong vessel.
