Bloody rust!!!

[Poecilotheria]

Just cant see how its happening, bike is always covered and cleaned. Never been let to be poured on in rain without its cover (oxford good quality one) but my clutch and front brake adjusters are now showing rust, my front disc was literally stuck to pads. My discs are cleaned weekly, its driving me crazy.

They're made from unprotected metal.

The brake discs in particular are exposed to the elements as the friction rubs off any coating to protect them from the elements. Add in heat from friction you get surface rust. It even happens on cars brake discs.

A cover won't prevent rust. If it's outside, it'll be exposed to moisture one way or another. Steel parts will be particularly vulnerable.

Storage in a garage usually will prevent rust, especially if it's heated.

The adjusters I would replace with alloy ones and any bolts that are starting to go I would look for your nearest plating firm, and ask them to Cadmium plate them. Don't let them fob you off with Zinc or Zinc Nickel.

That is super helpful, thanks. It seems good to have acf 50 looking at the control and test pictures.

I just got a pair of nissin off a scrap bike, I have looked for plate firms and there is one not far from me so will get them done before fitting I think.

I rode a £800 Chinese 125 through three Scotch winters and it was still pristine when I sold it on. It was ACF-50'd when fresh out of the crate, and re-applied each Autumn. Correlation doesn't imply causation, but I'm a believer.

That said:

There's a German product which I bought a while back (but rarely use) to stop discs from rusting. They allege that it has no effect on braking performance. Apparently used by motor dealers who display their vehicles outside.

AHB Disc Protector

[Loui5D]

The local allyearbiker guy has said that they offer another treatment other than ACF-50 called XCP one.

The promotional pack they sent to him made it look really good (as you'd imagine)

Tbh if it lived up to half of what it says it's almost as good as acf50

I spray a bit of ACF50 on to a soft cloth and wipe it on metal parts...exhaust down pipes and other places. Then I leave it for a day or two, when I start bike up to ride it the ACF50 seems to evaporate off as it smokes off looking as if bike is about to catch fire. What is best way to apply ACF50 ??

My Honda CBF125 had rust issues, to be fair, not as bad as my BMW Sertao.

My Honda I knew would need looking after from the threads on here, and unusually for me I cleaned it meticiu I can't spell that, carefully.

Yet I noticed rust streaks just inside the little fairing on both sides from a fastener.

Sertao ditto from the sides of the oil cooler but worse after being left out in the rain, once.

[Rogerborg]

Sad times, but common on both bikes. I'd have thought that all the oil leaking from the cooler would have kept the rust at bay though.

bike chain lube helps if you cant be arsed with ACF 50
I use chain lube on most exposed parts and reapply when needed hence why my msx is totally rust free

Maybe I ride to fast or too many miles but one application of ACF 50 does not last me a winter, tbh at the moment I am happy if it lasts two weeks.

Seems like I am always fecking cleaning the thing, despite liberal coatings of ACF I still have pits appearing on fork, wing mirrors and down by the tank hinge. It does take some abuse this time of year with all the salt.

I see daffodils and blossom so spring is here so the gritters can go back to wence they came and I can get back to my monthly cleaning schedule.

cheap silicone spray is the answer
its not a lube remember , just spray it on anything you dont want to rust including the exhaust , just keep it away from brake disks ,
its easy and cheap
