Could be cupping in the tire also.
That's a hum only new tires will fix

OP already stated no abnormal tire wear.

 

Subscribing. I have the same noise coming from my front wheel, worse when leaning left than right, but present any time I'm turning. Mine's a 13 with 14K miles. Been out of town all this week but will look into it when I get home. Good luck and keep us posted.

 

I suspect it's just tire noise. Every bike I have had has developed a hum when leaning slightly off center after a few thousand miles. My tires would do it even though there was no visible signs of uneven wear.

 

That drive belt should be as tight as a banjo string...

 

My 2011 has made that noise before, but with a few more miles on the tires than that. When they start to wear down, they will make that noise when riding sweeping corners at speed.

A tell-tale sign of a bearing gone bad is they will usually leak, spraying grease all around your hub area. If that's clean, they probably are good.

 

Does anyone know the bearing number?

 

Ya, that's always a good way to take out the bearings for sure.
I don't care what the book or dealer says there is no good reason to have the belt that tight. Only reason their tight from the factory is because a new belt will stretch a little then become snug like is should be.

 

Curious about the bearings as well. My front, right bearing is throwing grease. Not sure if that is a good or a bad thing. It is odd though.
