Warped rotors

bought a new screaming eagle ultra in 2011 with fancy front rotors looked nice - within a few weeks the front rotors were warped bad to the point the front brake lever would bounce in my hand was driving me crazy not to mention could be a safety issue especially when wet. took it in they asked if I was towing - no and never had anyone on the back - they told me it was rider ware and tear and would not be covered under waranty and the fancy rotors were $250 each - they did highly recommend that I have them switched out because they were not safe in that condition - I told them to take back the bike and asked for the number to harley corp and highway safety dept - I sat in the corner for a half hour - they told me they would make an exception and replace the rotors free but only once - for the next year I was very carefull with front brake often only using back brake, down shifting like crazy - always thinking about it - at about 9k miles the rotors warped - I gave the bike away cheap. found out later this is a big prob with harley accross many models - not big enough rotors - more metal = they will take more heat and stay tru. I just bought a new '14 ultra limited - because harley has fixed the prob with bigger heavier rotors on this model - with integrated brakes I just use the front brake anytime as much as needed - with 6k miles on no prob just smooth braking
