Rust on lower fork bracket

[Guth_imp]

Not sure what the explanation could be. There is plenty of wetness here in the Pacific Northwest. I just gave my CB a good look and find no signs of rust. Dirt and road grime, yes, but that's it. My bike is really due for a washing.

I'm in the Pacific Northwest too. I keep it in a dry shed where I keep my tools and nothing else in the shed is rusting. It does get wet sometimes when I'm out on it but nothing out of the ordinary. Rode plenty of bikes in wet weather and never ran into this before

I'm guessing that they will measure the paint film thickness and find out not enough paint was applied.

Maybe there is something to the production run theory. Wonder if the VINs of the bikes in question are close together?

Mine is Vin# 82

The CB is no different then the old UJM's. There's a lot for the eye to see which is the beauty of the bike. Along with that comes pitted shocks rusty exhaust collars (but our rims should stay in decent shape) There is just to much to view not to see imperfections. The newer bikes today have rear mono shocks and are covered with painted plastic parts.

Look at the barn finds of the 70 and 80's, most have low miles but are rusted beyond repair. Whether you store it or ride her its going to age.

Just ride it and enjoy it.

Thats exactly the conclusion I've come to, I think they have made them the same as they did 35yrs ago.
Anyway, did the rear fender yesterday and its looking loads better today, took front fender off today, clean and treated with Acf50, 10 min job.

The CB is a beautiful bike and if it takes extra care to keep it looking good then thats fine with me,

Any protection used under the fenders will have a very difficult job. That's a spot that is constantly being washed and abraded by road chemicals, sand, pebbles, and water thrown up pretty forcefully by the tires. Without additional protection, even a thick chrome plating will eventually be worn through to bare steel by the tire wash.

Something under there is probably better than nothing but if its painted or under coated, it will be difficult to get good adhesion to the chrome plating. If some paint ever chips off a little, that spot will become a trap for corrosion to start and eat under the rest of the paint or coating.

Makes me think about attaching some sacrificial zinc anodes like they use on boats.

Since I have a 2014 on order, I'm going to make two assumptions: 1. All those suffering premature rust problems live on the ocean shore. 2. Honda fixed the problem for 2014.

There... now I feel a lot better.

Deanohh,

I work on a lot of small craft at my friends shop and own boats of my own. Sacrificial zincs on boats and outboards, outdrives, etc. work because they have a medium for current flow, i.e. water. The zincs do nothing for corrosion when the boat or motor is out of the water.

There are a number of corrosion processes. Corrosion control is a BIG DEAL in aviation and there are no zincs on any Naval aircraft that I have ever seen as they just wouldn't work. OK, seaplanes, I've never seen one...

Google corrosion types. It will be an interesting read. There are many types.
