'lantabusa, to answer your question, labusas folk come here to heap contempt upon other riders - I am referring to some of DP's posts on a recent thread - because they figure they are better riders/more hard core.
To summarize, if you aren't flogging your Busa, or not riding it to the edge of the tire, or you ever have an accident, then you are not meeting the labusa's standard, aren't a hard-core rider, and therefore deserve the contempt of better riders.
But what those guys haven't considered is the simple fact that an average (ho hum) professional racer is going to smoke the majority (if not all?) of labusas riders. And yet those racers aren't posting and letting us know how bad we ride, because they have no need to tell us how good they are - they already know. Does Carl Fogarty have to tell the world that he is a better rider than I? I think not.
It is the same thing in other sports. You have your local scratch shooting golf hero, who can smoke everyone in town and thinks he is great. Then one day he joins some low level tour, shoots an 85 trying to qualify, gets smoked by the competition and realizes that there are lots of players out there much better than he.
