My old BMW GS (motorcycle) engine jumped timing chain for whatever reason and completely gave up the ghost on a busy highway in Poland, a random motorcyclist on a streetbike saw the white smoke cloud and understood what happened to me as I coasted to the side of the road, he stopped, asked a few details and said "get on your bike, I'll push you to the nearest shop". I didn't speak Polish and his English was not great too, but we managed to understand each other. To this day I do not know how he managed, but he was able to control the gas on his bike, align himself to the back and off the side of my bike and kept giving me these push impulses so I could keep moving, and moving we were, we travelled ~6 miles to safety doing ~30mph, I thanked him and we went out separate ways. This experience feels surreal, I literally didn't spend any time in danger lingering on a busy road side or waiting for a trailer, which can take hours.
