Mustang as popgun and others have mentioned warped rotors are rear, it takes a lot of unusual force to distort the shape of one, let alone two rotors.
Let me tell you my story, the brakes on my cb919 were fine when i bought it second hand, one day i put it away after a wet ride and some time later i found some rust on the rotors from under the brake pads, i cleaned it off and from then on it developed this "pulsed braking", the brake pad residue had been partly and unevenly removed and the braking was somewhat less after the " cleaning ", it took quite some time to replace it and finally came mostly right by replacing all the front pads.
Rotors were never warped, i measured them with a micrometer dial but the grip on them was uneven.
