Whining from the back end - F3-S SE6

Hello all! New owner here. I just bought a (leftover) 2015 F3-S SE6. It had 15 miles on it and had been sitting at the dealer. This is my first bike, and I'm still learning all the in's and out's. I am noticing some squeaking during braking - am I correct to attribute that to the fact that it sat for so long? Will this go away or do I need to contact the dealer? Also, I am noticing a whining noise around 3rd or 4th gear, it sounds like it's coming from the back end. Does anyone have any advice? I'd like to call the dealer about this stuff tomorrow. 2 years old or not, this is still a new unit and they should've inspected it better, these noises can't be normal!

Just so the whining isn't coming from your passenger :yikes:

How is the belt tracking on the rear sprocket? Is is too tight against the flange? Never heard of that causing whining, but you never know.

Otherwise, maybe bad Rear wheel bearings from new.

When in doubt have them check it out. Good luck.

:congrats: on your purchase! :2thumbs:
Since the bike is so new: all of the bits and pieces are still getting used to each other. It always takes a while for everything to settle down, and get used to the program...
