Best model in my option esthetic wise, the high mount just has a clean race look to it. So far 5k miles in with no problems. I do also garage keep my bike and run water weter to keep my engine temperatures lower than others. So as far as the discoloration I've heard Delkevic being notorious for, I have yet to experience it for myself. Great product at and at its price point you can't get any better than this!
