Started to notice this after the 1000 mile service. At around 55 mph or beyond, I hear a random screeching coming from the vicinity of the right rear wheel. Doesn't do it all the time and it's not a constant screech. It'll go something like "screech, pause, screech-screech-screech, pause, screech" if that makes sense. There's no pattern to it. It sounds for all the world like metal on metal at the brake. Told them about it at the 5000 mile service, but the tech said they couldn't reproduce it and the brake wear is normal. I can see they test rode it by the odometer reading, which I took note of before dropping it off. I can't hear it when wearing my full helmet, but I CAN hear it when wearing my half helmet with open ear flaps, but even then not all the time. That's what's so annoying about this noise. I can't reproduce it on demand either, but when it's screeching I can't miss it.
