What they actually probably saved was needing to design a whole separate engine case for each bike in their lineup to match all their exhaust configurations.

The idea of having a little pipe protruding out is a different kind of bad design. Things that poke out from engine cases tend to snag or get punched in during a crash, turning what would be some scrapes on the block into a completely totaled engine.

And, specifically because oil doesn’t boil at those temperatures, it can be at much higher temperature than water can be as a liquid.

We tend to have a mental model of how much damage water can do at its “max” temperature, because liquid water stops existing after a certain temp.

But oil can be so much hotter than that, and still just be a liquid. It’s dangerous in that way, because while a drop of water at near boiling can only do so much damage but a drop of oil can be holding a lot more heat and hence cook a lot more of your flesh before it runs equalizes with the surroundings
