Having done CSS Levels One and Two, the most valuable lesson I brought with me from CSS is " DON"T PANIC!"
At every given speed, line, corner entry, straight line, most of us are never near the limits of what the bike can do. However WE do make mistakes. How we react to the situation at hand determines the outcome. I've make many mistakes on track, going at high speeds, yet my worst outcome was just running off the track. Where as many other riders lowside, highside, wipe out, hit other riders. On the track, having the run off room, I choose to stand up my bike instead of grabbing the brakes, chopping the throttle, or anything else that could upset my bike at full lean. On the street I just slow my pace down. In the canyons, I usually do a slow run to check the conditions for gravel, leaves, etc. Then I turn around and run it again at a faster but not race track pace.
