I agree that H-D riders can be very tolerant of BMW riders. I went to Cold Spring near Santa Barbara, a noted biker bar of sorts with the H-Ds out front, Euro bikes to the left and crotch rockets waaaay down the hill to the right. I, of course, got asked by the bartenderette what my ride was. At the time, it was a 1983 R65. The biker to my left asked if it was out front. I had to tell him no, as I was out west on business. When asked how I got there, I pointed at my friend next to me. They asked what he rode - a GSXr 1100 I said.
After the deafening silence of a lot of seconds, they said he could stay because he was with me.
