I am trying to read everything I can about track days before I go to my first one in a month or so. My wife got me a copy of Twist of the Wrist which I just started reading. I read in a magazine that a lot of people shift their bikes without the clutch. I tried this a couple times today and it shifts very easily with a simple throttle off shift. Is the wear this saves on the clutch worth it? Does it shorten the life of the trans at all?
