I pull up to a light, and some guy pulls up next to me on a new 600RR wearing a t-shirt, shorts, and a helmet. We start complementing each other's bikes and then I shut my helmet and rev the engine. Waiting for the light to turn, he's reving away also. Light turns, and in about 3 seconds he is barely discernable in my mirror. Now, I know that the bikes depend on rider, but wow did that bike get beaten like a wife that doesn't cook and talks back too much. Of course, I slow down since I'm speeding like crazy, and he flies by me about 2 seconds later. Must be a real newbie or the clutch and starts are not nearly up to par as the 636.
