BigDoug, nice job on the control after a blow out.
Please don't take this the wrong way but I'm assuming that was you in the pic standing next to your bike before it was loaded?
I don't know the size of your partner Linda or the weight of the bag you had on the back but if that was you, you're not exactly a small boy.
The load index of the Avon Cobra AV72 is 84 (1,102 pounds, 500kg).
Max load on the R3, according to Triumph, is about half that (517 pounds, 235kg).
Not saying this was the cause, but depending on the combined weight, it may have been a factor that Triumph or Avon will use to not honor paying to repair.
