A friend has an old BSA. Some big thumper from the '40's. First time I saw it run was on its centerstand on a concrete floor. You had to keep an eye on it, because it would vibrate across the floor and ram itself in to whatever else was in the room if left alone đŸ˜‚
You could say the same about my 2006 640, I stopped to take a leak and left it running and found the damn thing 30 yards away on the other side of the road.
