Rotors

Postby toanogreen » Mon May 13, 2013 9:11 pm



I had my wing inspected last week and I had to get new tires. He said everything else was fine. I got the tires from another shop (better price) and I had them put them on. The guy calls me up and says that the rotors are shot. He said they were so bad he didn't want to let me ride home. Not having any more cash for this (over $1000 just in parts) I just told him to put on the tires and I'll take it home. I picked it up and rode it home. Two days later I took it back to the original inspector and he said he didn't see any problem. I am going to have someone else look at them again. Note: The bike only has 62K miles.

My question is what are the specs on the rotors? I'm sure they are somewhere, but I can get answers here faster than anywhere else. If I do have to replace them, what should I get; OEM or aftermarket? I don't do heavy or hard riding, but I do ride to work regularly.

I don't know the spec for your rotors, but it is usually marked on the middle of the disk "min thk 4.5mm" or something like that, so you can measure the thickness of the disk and see if it is okay. Be sure to measure the thickness in the middle of the pad swept area (Not at the outside edge of the disk).

Thanks. I will check to see. The more I think about it, I will probably go on and replace them either way. I know the rear needs to go, but should I go ahead and do front as well?

Rotors are not cheap, unless they are warped or worn out, I would not replace them!! If you have to replace one of the front, then it's good practice to replace both as they work together, but if the rear is worn and you change it, you do NOT need to change the front unless they are also worn.

I suppose it's possible but I would be surprised if the rotors are worn out at that mileage.

I believe there is 2 different min thicknesses. 5 and 6 mm. Like already mentioned, they are printed on the outside of the rotor.

Brand new rotors cost over $300 each, so if you needed all 3, $1000 is reasonable.

But used can be had for between $20 -$100 each.

However, with only 60K plus miles on yours, it is very unlikely that you require 1, and even more unlikely all 3 of them. But it could be. Age has nothing to do with the longevity of brake pads and rotors, it is how you drive it. If you wore your pads down to the metal and continued driving it, you could make toast out of your rotors with the original set of pads.
