Kind of hard to describe, but I am trying to chase down a noise/vibration in the front end of my 12 Harley Ultra Limited (16,000 miles). When I lean the bike just a little (like to change lanes) I get a little bit of a whirr noise and the slightest hint of a vibration. Doesn't happen when running straight, or when making the same maneuver to the right. Only to the left. Also does not happen when banked hard (like for a sweeper turn, or a turn at an intersection).

First thought was a bearing just starting to act up. Or maybe a little loose? Or could just be tire whine, but only on one side?

Any ideas or anybody ever have this happen to them? Figured I would throw it out here first. My next step is pulling the front wheel and checking the bearings....

 

I'm gonna guess, Wheel bearing...

 

 

wheel bearing

 

I had the same thing on my 09, only when leaned to the left. It was my rear tire. Replaced it and not more whirr noise.

 

I had the same problem on mine. Dealer found bad wheel bearing and replaced it. No change in vibration. They and another dealer said cupped rear tire was the cause. I just put new tires on the bike but it'll be a few months before I can ride. Hopefully that'll fix the problem because warantee is over. Joe

 

I've changed my front tire twice, had the bearings checked and repacked and I have the same exact issue. Going down a smooth road and just shifting to the left it still feels like a bad bearing but isn't.

It's so minor I don't let it distract me too much. Everything is solid and tight.

I've wondered if my alignment may be off just a little.

I'll be interested in hearing others comment on this post.

 

Check for rear wheel alignment . Friend of mine had same issue and that is what the problem was.

 

on my 2011 it was rear tire . dealer said put 42 pounds in it , it was gone I ran 35 it was cupping very little .

 

Had same symptoms on my then new 12 RKC,took it for granted dealer had checked tire pressure,they hadn't.Filled the tires up to proper pressure and it went away.
