There is always something that messes up. You are the one who needs to deal with it. For example, when it rains here in Bengaluru, the Kutcha road (for approx 200 meters from my home)turns into a sludgy road. My motorcycle will be completely filled with dirt after raiding for a few meters from my place.
Once my motorcycle is dried, it becomes very difficult to clean. It needs a complete water wash. The problem with water washing is, the motorcycle will lose its shiny color after a while. You need to grease the vehicle too. At least, it has come to my experience that, the chain definitely needs it. Else, it’s going to make a lot of sound.
So, there is always an opportunity cost.
