I suspect they're the same, they're both working similar sized two pot calipers... if anything the KX will have a smaller piston to keep from being too agressive?
I can't find the piston size for the KX but I can see inferences that it's a 10mm to 11mm unit, the Ninja is listed as either a 13mm or 1/2" bore, so it looks like the Ninja would give a bit more volume.
