OK, I'm calling BS on that story. I ride most every day, and often "enthusiastically". There is no way in the world that ANYONE can be riding at a high rate of speed and drop his drawers.... probably not even at a sedate speed. One's right hand must stay on the throttle, right? So your buddy had to stand up while playing cat and mouse, and drop his pants using his left hand only? Sheesh
I live on SR 20 in Washington and the summer is alive with motorcycles heading into the North Cascades. My obsevation is that all Harley riders, while not strictly obeying speed limits, tend to ride safely and usually in groups of 6 to 20 or more. However, the high revving, high power imports tend to ride solo or in groups no bigger than three. Their speeds border on insanity often passing my front door at 80 to 100 plus, passing cars in dangerous places and sometimes forcing oncoming traffic onto the shoulder.Motorcycles are 2 wheeled suicide machines.
