Countersteering is a basic principle of turning. As you lean, you are actually pulling on the handgrip opposite the lean (turning the wheel out). Therefore, you are turning the gyroscope (wheel) away from its direction of travel. The gyroscope will attempt to correct, causing the bike to turn (the bike is attached to the wheels you remember). Try this little experiment on your bike - drive straight, pull on you left grip very slightly and watch yourself start to bank and turn right. Countersteering is related to physics, not "precession[?]". When you come out of a turn you are letting up on the countersteer, not increasing it. Please take an MSF course.
