its not as easy as just replacing the buttons. You'd have to drill out the original buttons and the install the floating ones.  Those are like $10 a piece. I think there are 12 buttons on the dual rotors bikes. Not cheap, you might as well get the floating rotor to begin with

Thats for the front, but what about the back??

[bryant8]

the back I don't believe its a necessary thing to do. Only about 20% of the total stopping power is in the rear when you apply both brakes. If you did it would probably require a rotor carrier

[LYD]

Thats what i thought. Kewl!  Maybe a later date for the front.  I know fussion629 (ruben) did his full floating front rotors. I can talk to him on how hard it was.

While we're on the subject of floating rotors, does a '04 "base" model 999 have floating rotors?  What about the twin 320mm rotors on the 620 Dark?

there should be noticeable play in the rotor if they're floating...you can jingle the buttons by grabbing on the rotor and moving it back and forth.

I've heard the term, but I have no idea what a floating rotor is...

[never2loud]

I think I know just about enough to be dangerous on this subject, but here goes:

If you look at a front rotor, there's the shiny silver outer perimeter that gets clamped by the caliper pistons. 

Then there's a separate inner part of the rotor that is made of a different material that the front axel goes through. 

There are half a dozen little bobbins that hold the two separate parts of the rotor together; the bobbins allow the two parts of the rotor to move slightly when the brakes are applied so it is termed a "fully floating" rotor.

Why this is an advantage, I'm not entirely sure    Probably has something to do with heat dissipation/warpage issues...


Help me out here, David... Please

haha, floating rotors allows for slight warping in your rotors.  usually what happens if you're not floating is that if the braking surface is warped, the caliper moves back and forth going over the undulations.  Moving caliper sends vibrations up through the forks, etc ... Floating braking surface allows the disc to move around while the caliper stays put and all the vibrations don't transfer up through the bike. 

unless you have majorly warped rotors, you shouldn't notice a difference in braking power...

AHA!!!! (light bulb turning on) I just learned something about motorcycles on a motorcycle forum... What are the odds?!?!?!? 

Now let's cut this techie mumbo jumbo. When's lunch?

oh, before we do that, I forgot, you can float your rotors FOR FREE

If that could possibly make my Duc make even more clattering noises, I'm in.

my full floating after market rotor on the monster is ridiculously noisy

do tell

Talked to randy today about full floating rotors and doesn't recommend them for street use.  He said they are great for racing, but not for street!  Call him and ask him!!
