Back in the late 90s early 00s we were into Ducatis, both on road and track. We an others in the Ducati community had a string of warped rotors, on new/low mileage bikes. To cut along story short - the conclusion was inferior quality in either material and/or production. and nothing you as a rider did would make any difference. Either they warped or they didn't. We routinely replaced the OEMs with ISR discs which never warped and had better bite. Costly yes but so worth it. If my CB developed pulsating I'd not faff about trying to fix it. I'd go straight to ISR and consider it cheaper in the long run.
