John, I also have a 2005 America. I bought the bike with 1600 miles on it and it already had a warped front disk. Evidently Triumph has had a problem with factory defective disks. Mine was replaced by the local dealership for free under warranty.
Take your bike in and tell them you think you have a defective warped rotor and see if they will replace it.
