Well, maybe by that time they'll have the 6th gear whine at 35-40mph figured out....

If you have nothing to lose, just go to the dealership. It sounds like it's either normal or not a concern, but I'm sure you'd rather be safe than sorry.

 

If its under waranty then take it to the stealership...they will tell u that u shouldnt have it in 6th gear going that slow (even if ur in 6th going just over 80+....ur still goin to slow) and they will just laugh at u behind ur back. If u try that rear stand thing ur bike is gonna slip and, well if u have ever seen the movie ferris bueler's day off then u allready know what is gonna happen. Dont worry bout the noise. There really isnt any need for u to even be in 6th gear anyways right now. Wit 800 miles on it u should still be brakin it in, imho. Take her out for a couple hours this weekend and hit 4th gear at the most (no more than 120mph) and u will be fine.
