i've never spoken to them but every now and then(3 times that i can recall) i get behind one on a tight trail and they won't move! are they thinkin' ? that they're fast enough to run with a yz 450? i try to be polite and ride just revving it up a little behind them ,but it always ends up with me having to pass them in a fit of rage,dumping the clutch in 2nd gear with my 120's spitting whatever terrain it happens to be into their smug little faces,while my 102 db exhaust rears them into a deafened state that they could have avoided just by getting the heck outa the way!!!!
