This motorcycle swing is not something that should be tried by amateurs at home! Sturdy ropes suspend a motorcycle from a long crane arm high in the air, but again, the balance and the measurements have to be exact, just one miscalculation can lead to disastrous results.
How can this swing be safely accomplished? The motorbike needs to be completely suspended, with no initial contact with the ground. Once the rider is in place and the motorcycle is completely level, the rider can lean backwards and let the rear tire touch the ground. At that point, the rider accelerates gently to start the swing’s motion. The same acceleration made several times at the same point in the rotation arc will increase the speed of the swing, the trick is for the rider to not lose their balance.
For braking, theoretically, the rider would do the inverse to slow the swing’s inertia. Watch this video clip to find out how it’s done properly, but please remember this is dangerous, and you should not try it at home:
