Did my first track day this week at Lime Rock Park in NW CT. I rode my Beemer, and everybody else in my class (track novice) rode race replica sportbikes. Only a couple of the class of about twenty were first timers, so I got passed a lot (although I did pass two or three myself). I did run off the track once, but kept the bike vertical. All in all, it was both a humbling and enlightening experience, but one that I'm very glad I had. There really isn't any substitute for the track (with instruction from the coaches) to learn how to ride aggressively at speed, in relative safety. I learned that my bike and tires would take care of me at much greater speed/lean angles than I had known before. My formerly significant chicken strips are now mostly gone, and back on the street I can feel a difference in my riding. Not huge, but it's there. If you get the chance, this training is worth the effort.
