Anybody know what these marks are on my CB125R 2025? It’s definitely not dirt or road grime, as motorcycle degreaser cleaner doesn’t seem to budge it. It is a fairly new bike, so didn’t know if it was fixable, and if it was corrosion, I would expect better quality from Honda.

Started to notice what seemed to be rust forming around and inside what I believe to be the drain tube in the filler neck of my CB125R. Any ideas what this is, or what could be causing it? I’m pretty new to motorcycles, and it doesn’t seem normal for something this new.
