Fork tube rust

[melfl_imp]

Every CB1100 2013, 2014 In my area has pitting and fork tube rust. Little to nothing else has rust. Are there any options for stock size chrome fork tubes? Anyone else with this problem? Even the bikes with low miles that sit inside have it.

G'day Melfi. Welcome to the forum.

The CB1100 (heck, any motorcycle owner for that matter) folks in England tend to treat their frames with ACF-50 (and similar competing products) once or twice a year to combat corrosion.

ACF-50 is made in my old home town of Mississauga, Ontario, Canada.

You may find a lot of it is light surface rust rather than pitting. Get some aluminium foil, scrunch it in a lose ball and wet it. Then lightly rub the fork tube. You may find that takes it all off. The soft aluminium will not ruin the hard chrome but no need to pres hard regardless as that can have a little dulling effect if you really go at it.

Remember to wax the fork tubes to help protect them, especially from high humidity and salt air. Under those conditions, putting a cover over the bike can accelerate corrosion. It can trap moisture and create a sauna as the sun beats on the cover.

Yes, my fork tubes began rusting, and pitting. I live in San Diego, Ca, and several miles away from the coast, so salt-air is not an issue, especially since my bike is stored in a closed garage. I take excessive care of my motorcycles, and of all the bikes I have owned (over 25) , none have experienced rust like my CB1100. I have two bikes over 45 years old stored in my garage that have experienced less rust then my CB1100. I have seen excessive rust beneath the fenders, and on the handlebars. My bike has only been ridden in a mild rain twice since I have owned it, and I cleaned and dried it each time immediately upon returning home. I used the excuse of pitting on my fork tube to purchase a new pair of stock, Honda Big Piston forks (used on the 2017 year model). I believe that Honda cut corners when they applied the chrome plating on my 2014 Dlx.

Back in the day, I bought my used Kawi Nomad from a dealer 40 miles from the ocean. There was not a speck of rust on it. Within six months, the forks were showing rust from riding up and down Pacific Coast Hwy. My 2013 CB, with less than 8k miles, is showing pitting on the forks too.

Even though I live 50 miles from the coast my 2013 suffered from rust on the fork tubes, triple clamps and oxidation on the cam covers. Never had a bike this rust prone before and I stayed after the rust constantly. The only real complaint I had with it.
