Rust on front rotors... But from what?

Same old fuxking rust on my pani too !
Never on my 1098s nor Ktm 690smr.
Just ride it anyway........that's part of the deal with iron disc .........it's normal.

I always use WD40 to clean off the sludge from my chain for years....then I use chain lube after! Never had problems with my chain....whats wrong with using WD40 on o-ring chains?

There's an argument that says if WD40 gets past the O-ring it'll degrade or completely remove the grease applied at the factory and knacker the chain. Depends who you talk to as whether this is actually the case. Also any excess lubricant left over will continue to degrease the chain after you've re-lubed it.

Everyone has their own ideas but I would NEVER use WD40 on discs. For me a lubricant that degrades performance is a definite no, regardless of whether it will wear off or not.

There are plenty of products on the market that will do a better job than WD40. I've always had great results with Wurth Brake and Chain Cleaner. Only £5 a can, for the amount you'd use it the cost is negligible.

I'll sometimes use WD40 for other cleaning although prefer GT85, smells nicer!

Just ride it!
My opinion is that you dont put WD-40 on your discs or Armorall on your tires!

Panigale is so sexy it made me want to give it the Jackson ....... treatment?

Seems like WD40 on the rotors would be an effective way to turn that rembrant in his living room into a picasso.

That is awesome.

And I agree, I thought the WD-40 comment was a joke, along the lines of putting armor all on your tread (which I knew a guy who did). People do what you want, but the concept of putting a flammable lubricant on brake pads and rotors seems patently absurd and dangerous. And for no reason, since riding will naturally wear the rust off. Might as well put a coat of RustOleum spray-paint on your rotors as well.

I will never view a ....... painting the same. Thanks. Though the Pani is certainly Georgia O'Keeffe-esque.

Wait, I shouldn't have painted then with rust oleum? I even found a red to match the bike. Maybe I can take it off with some WD40.

You mean "low information folks" like DarioDuc?

Hey efna .... off. If you have nothing positive to bring to the thread then dont comment at all. Get a life and try not to feel so high and mighty on a ....... online forum. I dont want to read through your sarcastic ........ so quit your commenting.

Why thank you for your heart-felt retort. Would you care to borrow some WD40?

For whom it may apply: "To each his own"

Use some WD-40 on it at your own risk, will make the brakes a little slick for a minute til it wears off. Otherwise, it'll come off when you ride it.

That is most stupid thing I have heard anyone say on this forum.

It is good for cleaning your wheels, let's not discount this great product completely!

I dont think anyone is discounting the product. Its great for many uses. I always have a can on my shelf. I just offered some to DarioDuc too!

Shouldn't be worried about rust on the rotors...

This happens all the time with cars and bikes. The rotors in my cars and bikes get rust "traces" on the rotors after any sign of moisture... car wash, humid environment, etc. It shouldn't be a concern. just ride it for a few minutes and it's gone.

Different issue but since it was mentioned here... the tire protectant on the tires... I remember this happened at a carwash some years back. A carwash employee was a newbee and wanted to impress me and to get more tip from me and he applied tire protectant on my bike tires. I noticed it and told him not to do it on motorcycles anymore and had him wipe off and rode it carefully as if it was brand new tire installed. Wore off in minutes.

Should never let your guards down on any surface you ride on... especially on the streets. Oil spills, coolant drips, construction debris(such as dirt trail), pulling out of a slick carwas lot(mix of water and tire protectant and soap), etc.

I ride as if a mix of all of the above is going to happen at all times. Don't take it for granted

On a different note... I know a motorcycle collector that has got many collectible bikes in his office and he has his maintenace guys apply moisture repellants on the metal parts such as rotors for "looks". That's ok.

Not worried about rust on the rotors themselves... But on the balance of the parts on the brakes? Is this normal? Does anyone else have similar rust on their brakes?

I don't understand this whole thread. Rust is an interaction of Iron /oxtygen / moisture. So any metal that has iron in it, and is not painted /treated adequately, in a climate with greater than 0% humidity, will rust. Simple physics.

Simple chemistry.

2Fe(s) + 2H2O(l) + O2(g) 2Fe2+(aq) + 4OH-(aq)

Fe2+(aq) + 2OH-(aq) Fe(OH)2(s)

Fe(OH)2(s) =O2=> Fe(OH)3(s)

Fe(OH)3(s) =dehydrates=> Fe2O3.nH2O(s)


You must be one of those "low information folks"

Rust causes an increase in entropy, therefore physics.

That's a stretch, so does this thread...
