Why I do not ride a motorbike

When I was young and stupid I hanged out with a boy who had a big Kawasaki motorbike and one day he was going to give me a lift for several hours in Greece. Going from Evia to Pirgos Dirou in Peloponnese. I had no helmet and we drove 190 kilometers per hour. Suddenly the chain jumped into the rear wheel and got stuck in it. The motorbikes wheel stopped spinning and the motorbike slided straight for the mountain wall. As of a miracle the bike stopped just a couple of centimetres from the stone wall. I have heard that the bike should have volted when this happens but it didn´t. Not to mentioned a burnt leg and bruises in two other accidents so it is really safe to say that no more motorbikes for me.
