Hello mechanics and enthusiast. My question is a bit hard to explain and visualize so I added a photo:
This is an image of Honda Beat's rear. I came upon this question while I was cleaning it this morning.
My question is, what is the purpose of this design? I mean, it makes more sense to just fully isolate the inner engine parts from mud and rain instead of having this flimsy cover as protection. Is it to cool down the engine? But most of the time mud gets to the wiring cables inside. And why a flimsy cover instead of a solid plastic mudguard?
