Anytime I corner at above necessary speed there is a fear--level dependent upon my speed. This is just natural survival instinct! Your brain has realized that you are not indestructable and is reminding you of this fact. I just overcome the fear (this is pushing your limits) and ride on. You stated you crashed which has caused this feeling, time will increase you trust in your ability and equipment back to your old limit and possible beyond. There is nothing unusual about hesitation after an accident. Just ride where you are comfortable till that level rises
