Front Disk and Disk Guard for the WR 450

After the last race I noticed that my stock front brake disk is out of round enough that when I spin it on the stand, it stops when it comes to the places it's been hit by other peoples roost. The stock unit is a floating disk that Yamaha wants $150. to replace. I found and purchased an EBC contour rotor for $89.00 and am searching for a plastic disk guard. I got one from CYCRA they said would fit, but it doesn't. It's for the YZ

and the bolt holes don't line up.

My question's are;

1.) Is anyone else using a non-floating front rotor, what type, any problems?

2.) Have you found a front disk guard that works on a 04 WR 450? Has anyone tried the ACERBIS universal.

My bike has the floating front disc. Why do they build them like that? What is the advantage?

I have the acerbis on my 04' wr450 and it works great and easy to install.

Supposedly, the advantange of a floating disk is when it gets rock hits or dings, it can allow the disk to move a little so it can pass through the caliper with out binding. Several of the high end oversize rotors offer this feature...

usually at a price of over $200.00

Does it mount via the axle hole? Or does it bolt on somewhere?
