Re..motorcycle etiquette, Sorry but there is none, motorcycle riders are and have been treated like outlaws ever since i have been riding. Some people give a dam and most people don't. I build costom Triumphs and ride them and I also have a 2005 America and also a 1966 B S A stock 650. If I was to get into the different kind of behavior I get from cagers and from other riders I would be here all day. If you put your hand out to a fellow rider and he doesn't acknowledge it, he is either watching something more important (a cager about to run him over) or he is just arrogant. If he does wave back (in my books) he is acknowlegding the fact that wether you ride on weekends or ride 24/7 like myself he understands the brotherhood (and sisterhood as my girlfriend rides right beside me all the time) that everytime you throw your leg over your steed you not only run the risk of enjoying what riding a bike is all about but you risk your life in wanting to feel that freedom. Just don't take it personal. Just look at everyone else on the road as if they are out to run you down and you will survive wether you ride with an etiquette or not. How ever you ride just make sure it is defensive and curtious and you will be fine. And most importantly, keep the wind in your face and as many bugs on your teeth as you can. Smile all the while.
