It would be extremely rare to have a major internal gear issue on a bike with 11k miles.
It would be far more common to have the noise be related to something that has been done to the bike after it was sold at the dealership. Some goofy mechanic messed up an adjustment, or some aftermarket part was too cheap for real world duty, or it was installed incorrectly. These are the things I see everyday.
Lets see a video and keep in mind the quality of the videography can directly influence the ability for me to spot the issue. So don’t “put the blinders on”. I want to see the whole bike, the aftermarket mods, the drivetrain, how you ride, etc.
I’ve seen videos come back where the guy has a car tire on the front, fork oil leaking down on the brakes, a chopped off rear fender with a custom wheel from a Harley poorly fitted up with homemade spacers, duct tape streaming off of loose wires hanging from under the tank. And then the guy rides it at 1700 rpms on the open road, never shifts over 3000 rpms, unless he’s doing a 6th gear burnout. All kinds of weird crap.
