Now hold on there big fella!

I am an old school waver because that was the way I was brought up. In the 50's from about age 5, riding poker runs on the back of my Dad's Harley or Indian, I was taught to wave to other bikers. There were no Jap bikes then, and even the Brits were considered somewhat exotic, but you waved at ALL bikers regardless. Back then, it was part of the mystique of biker world, almost like a secret hand signal acknowledging that you both understood the "magic".
I've owned 2 Harleys; an Ultraglide, and a 1200 Sporty, and of course the Harley guys waved at me when riding one of those. However, when I was riding another make, many no longer waved, which made me consider how pretentious and snooty the whole custom had become. I've even had Harley guys start to wave then withdraw their hand when they realized I was not on a Harley - funny!
One thing that kinda irks me is my Beemer isn't usually offered the respect of a wave, even tho it has a heritage in Europe much like HD. BMW started out making aircraft engines, but due to the Treaty of Versailles after WWI, Germany could no longer make "military hardware". The result is, they started making motorcycles, producing their first boxer motorcycle in 1921.
I guess some Beemer guys are a little clicky, but the ones I've met are wavers and not hostile in the way some Harley riders seem to be. Having owned both Harleys and Beemers, one distinction I noticed is a Harley is expected to be shined and polished when you ride into a rally like Sturgis, whereas Beemer guys are completely opposite, almost taking pride in the mud splatters, dirty windshields, and camping equipment bungied on.
One last thing is, I don't wave in town. I'm usually too busy shifting and avoiding cages to be bothered.
