I live in eastern Washington. There is a nice loop I like to ride some evenings after dinner that takes me down into Oregon, east along the Columbia River, and back into Washington a bit west of Walla Walla.
I was on my GS adventure, with panniers and top box on, in an area where a county sheriff often likes to set up a radar trap. It was a 55 zone, and I was cruising along right at 55. I see what looks like a bike in the distance behind me and think it could possibly be a motor officer, so I stay right at 55. It gets closer and I see it's a couple, two up on what looked like a Fatboy. I hold my lane position and speed. They swing out to pass me and I keep my speed exactly the same. I didn't do a thing. The passenger, a lady, is in short shorts, a tank top and flip flops. I make a mental note to hope she has an opportunity to speak with someone who has had skin grafts and then reconsiders her riding attire. To each their own though. This guy proceeds to aggressively swerve back, right in front of me. His rear tire was less than 5' from my front when he whipped over. They both extend their left arms and give me the bird, and then high five each other! He then blips the throttle several times, as if the sound of his manly ride will surely impress me. At this point the part of me that was saying it's just a couple out for an evening cruise was replaced by a voice telling me "oh hell no!". I realize I probably looked much less cool than them, and probably a bit goofy, in my riding gear, boots and full face helmet, on the funny looking foreign motorcycle.
I rolled my throttle on. By the time I was at about his 8:00 he realized I was passing him and I heard his bike start to make a lot of noise, but not exactly leap forward with any sort of urgency. I didn't even look over at them as I passed. He continued to try to catch up, and I witnessed a couple of really stupid passes in my rear view. Even though the GS is far from a sport bike, I think he thought his hog should suck me up and spit me out. Somehow I think he was genuinely surprised. He became smaller and smaller in my rear view and when I hit the twisty section of the ride I never saw them again.
I have owned some different looking bikes, and have always been amazed at some of the comments from some of the HD crowd, like "when are you going to get a real bike?". I travel quite a bit on a bike, and really enjoy talking with other riders. I would never insult someone else's bike, no matter what it was. One time, when I was on a panhead, I had a guy on a much newer HD tell me my bike couldn't be a "real" Harley. Where do some of these folks form their ideas and come to think that HD is the only company that makes real bikes? I don't get the air of superiority at all, or their apparent disdain for anything with two wheels that isn't an HD.
Oh well, thankfully they still seem to be a rather small minority.
