While riding my Buell’s (kind of a HD but, considered a sport bike). I used to drop my hand low and way out, almost like reaching to get a five slap. Funny how many did the same in return. Of course I was an odd site. I was wearing black leather on a sport bike. That kind of threw people. I wave when I can, my passenger usually will (and gets a kick out of it). I will give a nod when I am busy protecting myself. What a great topic. In the class it is usually mentioned that KIA owners don’t seem to wave to each other. Sometimes old JEEP owners will. We are a pretty strong community (motorcycles in general). Just see what happens when you are broke down on a major highway on your way to a rally. EVERYBODY at least slows down to check on you.
