Going too fast has nothing to do with your stopping distance. We time every rider coming down the chute, and the faster you go, the more stopping distance we allow you to get your motorcycle stopped.
This takes extreme mental and physical skills, it's not easy but it's something that will save your life, so do not take it lightly. You found out what areas you need to improve on, so go out and practice on your bike before even considering riding out on the streets. Remember, our natural human reaction whenever a hazard unexpectedly appear right before our very eyes is to SLAM on our brakes. Yes, you can get away with it in a car, but do it on a motorcycle, you will find yourself crashing before you even get to the hazard. Maximum braking is applying both brakes without locking either wheel. Or Swerve might be another option which a lot of riders forget to do. A crying shame in my opinion. If you never practice braking or swerving on a regular basis, you most likely will fail when the time comes to execute your corrective action.
