Break rotor, what does it fit?

[Varmit57]

I bought a set of wave break rotors from a guy on Ebay that was suppost to be for a 400ex. I used the fronts and put the rear in the cupboard. Now about a year later I pulled it out and noticed that it is not the right size for a 400ex.

I would like your help in identifing it.

The bolt pattern is 4 x 3 5/8" and the outside diamiter is about 7-3/8". its a custom built flamed style and has no part numbers.

Thanks......

Probably for a 250R if its smaller.

I run a 250R axel in my 400ex and the bolt patterns are the same, this one is a lot smaller........

I may be way off the wall here but could it be a front rotor? I ordered a rear wave rotor and when it cam it looked like a front rotor not a rear so I had to send it back.

I checked and the Fronts have only 3 bolts.
