Hello, new member here, first post. 
(I have tried searching the forum for this but came up empty handed so I'm hoping someone can answer this or point me at a thread that does.)
I've recently purchased a brand new 2023 C400GT that the dealership had on deep discount as it's been on their sales floor for a couple of years. Although it's a couple of years old it only had 30 km on it from a test drive or two so I'm considering it to be in "brand new" condition. The first thing I've noticed is that the brakes (pretty sure it's the front, not the back) squeal quite loudly at times, especially when braking at very low speeds in city traffic. It sounds just like what I've heard when indicators on a car's breaks begin to squeal, letting you know you need to change pads soon, but these are brand new pads and discs, so I'm wondering if this is a problem, or just what these bikes sound like. So far there's only 450KM on the odometer, and I've really only ridden in dry weather so far.
Is it possible that this is just condensation moisture forming on the disc while I ride, which then gets evaporated after a couple of brake applications, then re-forms enough if I ride long enough without braking so that the sound happens again? As mentioned, I haven't ridden in the rain yet, but ambient temperature around here has been around 8-11Celcius (46-52F) and it is a humid environment so I'm wondering if that might be all it is. I haven't seen moisture condensing on my windscreen/body panels at any point while riding it so far, but perhaps the metal discs are getting cold enough from windchill while riding to form condensation on them, while the plastic fairings/windscreen do not?
Or is this just part of the break-in period for new brakes of this type? I've only owned one other brand new motorbike of any kind (Honda PCX150 scooter) that had a disc on the front and a drum on the back and I don't recall this happening when it was new (or after putting on a new disc and pads a couple of years ago). Is it possible that this is a normal break-in sound for the brakes on this bike and it will go away once the pads and rotors have married properly to each other? Is it possible that this is normal for most new brakes until they are run in, and that I just got lucky with my Honda's brakes? Any ideas or suggestions would be appreciated.
