Verify that psi and bring er up to 38-40 and see if that shimmy goes away. There has been a lot of speculation about those bearings.
Heres the good news, it's not always the bearings!
It may be a bad tire...dealer will usually replace..if they do replace you tire have them replace the valve stem with a steel one (you may have to pay but worth the bucks if you have it break on the road)
It may be low psi...increase pressure.
Heres the bad news, Honda has not been willing to step up to the plate on any I came across posting this type of trouble. There are some really reputable dealers out there that are willing to absorb the labor loss for good customer relations.
Bottom line, if you prove it to be the bearing just replace them and have peace of mind! With a little luck the class action suit against Honda will extend into the VTX line.
