Long before I ever did a wheelie, almost since new, my front wheel sqeaked a tiny bit, especially in the colder weather. It is sometimes audible with the motor off when I roll the bike. Sometimes not. My front brakes will make a little squeek under light application at very low speed. High speed, no sound. Rusty rotors are not uncommon. I believe it happens from even slight deposits of salt. It should ware off with use.
Warped brake rotors are mentioned by owners at times. It could be caused by long, hard braking at high speed. Warped rotors need to be resurfaced or replaced. Feel for a pulse in the lever to indicate warpage.
I think the comment above about searching for an unmodded bike is valid but sellers often undo mods before selling and keep mods or sell them sepparately. I've removed flies, I have done some revs to about 9K, got a few low wheelies with soft, natural touchdown - the bike runs perfect. I have 100% confidence in it or I would not be doing that stuff at all, ever. Keep in mind that the bike is really not best run at under 3K rpm (fuel economy is lower under 3K and engine ware might be a little worse, too). The bike is capable of 0 - 60 mph in 2.5 seconds. You can land yourself in jail for doing topend in first gear on any highway in this country. Second gear is potentially faster than the top speed most of the cars on the road are able to attain. You still have 4 gears after that. The bike likes to go fast. It wants to go fast. Low miles are good but reasonabley hard running isn't any big deal.
I really haven't heard much about little mysterious problems that got worse and worse until the thing broke down. I think if it runs good and you have evidence of proper routine maintenance, it will continue to run good for a long time.
