Would like to check something...

I have a Mtronics RV12 esc, is it okay to run these X2 motors from Orion (http://www.modelsport.co.uk/?CallFunction=ShowSpecification&ItemID=23564)

And what does the x2 actually mean...2 brushes ?...

Thanks :)

Yes, I think so.

x2 means 2 winds, double wind, ie two (thinner) wires wound in parallel instead of a single (x1) wire. x3,x4 are (were) also common.
