This is the first time my bike is on stands. I did what everyone does, I gave the front wheel a spin. I heard the front brake rub in one spot. Took a closer look and the right side of the rim isn't true. The right side of the rim looks ok. I have never hit a pothole or anything. I had noticed the rubbing a long time ago but HD never diagnosed the problem. Bike is out of warranty. Any possibility it's a bearing? How can this be fixed?

I doubt it's a bearing. It doesn't take a huge bump to put a slight bend in a wheel.

If you haven't noticed it while riding, don't worry about it. It's not a big deal.

Are you sure it is not deposits left on the rotor from your brake pads?

Yes, it's bad enough that I can see the rim move in and out. I will measure Monday but it could be a 1/16 of an inch. Just on one side, the other side of the rim is pretty solid. It feels jittery on spirited rides. Although it feels ok during inner city speeds.

My '08 XB service manual shows max runout, both radial and lateral, as 0.030in, or 0.75mm. The measurement is taken at the tire bead seat.

Hope this helps, Dave

It probably isn't bearings, but you might as well check them to make sure, its simple enough. It wouldn't surprise me if the wheel were just not made that well. QC from China usually isn't tops.

I sell newspaper equipment, do close tolerance assemblies and 0.75 mm seems like a lot.

If you feel something at speed, it might just be out of balance. You could get a rough feel for this by marking the low point with a grease pencil and position some kind of placeholder (a tool or any other object for general reference) then spin the wheel a little and see if it lands with the same point down each time. Spin both directions. If it does land near the same point each time, chances are good that the wheel needs a balance job.

FYI the front wheel on mine has this exact same condition on the same side, doesn't seem to affect the bike at all.

Greg, does your brake rub in one spot?

Yup. Doesn't seem to cause any issues with breaking. The rubbing at the rotor was the thing that made me look at the wheel and see it was also out of spec. Some day I'll probably get a new wheel, but right now I can't even seem to get the motor assembled so not a real rush.

Not considering a new wheel at this point. What I may consider is sending it out to get straightened. So far the that has stood out was this one I found.

I am pretty sure there is a shop in Houston or SA that can do it.

Although that website is pretty convincing that they are the best.
