care to explain that?

I really don't understand why.

While ductile iron is good, it's a cast material.
Stress risers like deep scratches, I'm more concerned about them in a cast material.

You shouldn't have any problems with cracking or breaking of Ductile rotors.

OP's rotors are prob not iron as they are stock.

The pics color balance made them look like iron

But none of them create a merry atmosphere of insouciance and bonhomie quite like a revving motorcycle.

Here's another picture, with flash, three days after washing them.

I will wet them overnight to see what happens.

It could have been nice/interesting if they were iron 8)

What makes me believe they are not iron:
   sold as steel stockers from a S2R 1000
   looks exactly like that   
   buttons have the flower shape washers on the inside = semi floating? (aren't all iron full floating?)
   traces of rust looks like on my own steel rotors
   (anything forgotten?)
