Below are good descriptions of how to make slow tight turns on a
big touring bike. It applies to most motorcycles of any size.

This technique will turn your cycle around in a two-lane road, leaving about 6 feet to spare.

The key to making nice, tight U turns is centripetal force. It is the force you can feel when you hold a spinning top, and try to move it suddenly. The top resists - the faster you spin it, the more resistance you feel. To make centripetal force work to your advantage, you induce spin into your engine components by revving the motor. Not blipping the throttle, but by running up to, and holding at around 2,500 RPM. The centripetal force exerted by your spinning engine components under these conditions is considerable - more than enough to hold you, your bike, your pillion and luggage upright while you maneuver through your turn.
