Rust on lower fork bracket

[Guth_imp]

Thanks Avi. It's always a shame and rather disheartening to see rust appearing on these bikes.

It's really hard to tell for sure, but looking at the images you've posted even if the rust didn't exist, the bike looks like it is need of a good overall cleaning. In the second image, aside from the rust, it looks like the rear fender; the chrome shroud on the rear shock; and the frame itself all look somewhat grungy. (Or perhaps this image is just misleading?)

In general, you shouldn't be experiencing rust like this. Still, from looking at the images provided you might need to perform a bit more upkeep on your bike compared to others depending on the particular conditions where your CB resides.
