The guy on the bike was Steve Jobs. When he was photographed by National Geographic in 1982 he didn’t want to pose standing with his arms cross in front of rows of computer terminals. Props for that, my opinion of him may have just gone up slightly. I tell you what though, the thing about those BMW motorcycles is they have horizontally opposed cylinders. Most American and Japanese motorcycles have two cylinder engines in what’s called a V-twin formation. The engines are pretty well oriented inside the frame. What you see next to Jobs left foot is a cylinder head sticking out farther than anything on the bike, which is just find unless you were to drop the bike and go for a slide. Since he wants to look cool for this picture he is not wearing a jacket, helmet or gloves so the damage done to that cylinder head is probably the least of his worries. The picture was probably taken at a very low shutter speed so he is probably not going as fast as the blurry background wire wheel spokes suggest. Hey kids, remember film? No, probably not. Replace shutter speed with frame rate for comparison.
