First off was the loose front end when I bought it. Tightened up and seemed OK ... for four years.


Though it was not as rock solid as my last full height 883/1200 standard Sporty. While there was no uneasy feeling at high speed it never has returned to straight from a handlebar shake as quickly as my old ride. I've previously chalked this up to less suspension travel and spoke wheels.


Also, if the bearings were damaged from their previous looseness, then the occasional bottoming of these short travel forks couldn't have helped them.


I've got standard firmness Progressive springs in the forks with 5.25" spacers and I'm now inclined to move up to 5.5" just to give them a bit more pre-load. But that's for after the current problem is sorted out.


I was told the tires were balanced. The front was supposed to have been re-mounted, but based on the ribs around it, it's still not perfect. I'll try a spin test of my own. But at 60mph there is zero vibration and perfect straight line tacking.


If new bearings don't fix things I'm thinking about leaving it with the dealer until they sort it out because at that point the ball is clearly in their court.

Post a picture of the tire where you think it doesn't look right.

The pics on my phone.

There are 3 ribs running around the bead. Both after the original install and the dealer's redo there's a bit of variation looking around the rim. They're not uniformly parallel to the rim.

The service Reps seem to think I'm being too picky, but they're not the ones who like to occasionally run down the road at 100mph on my Sportster ... but I do.

Do the ribs on the rear tire look true to the rim?
And the front rim runout, was the runout verified to factory specs? It’s in the book...

Here is one for the books: There is a local independent shop that I have taken my wheels/tires to that is notorious for mounting the front tires, on Sporty's or any make that has the disc on the left side, the wrong direction. I had to stand and watch, to make sure the tire ran in the right direction. Since most motorcycle tires are directional, this might be something to check because this can cause a lot of vibration with some tires.

Some tyres balance really well. Others require a lot of adjustment. If the tyre had to be reseated was the balance re-checked?

Update:

I'm taking the bike to HD on Thursday. In preparation, I backed off the bearing tension to 1.5" - 2" fallaway.

At that setting wobbling can be induced anywhere over 50mph. That shouldn't be hard for a test rider to find. Then the can run up the speed until they chicken out and back off. Nobody wants to crash. I sure wouldn't want to hit any bumps with that shaky front end.

Also, I lifted the front wheel and spin tested it. Eyeballing it for wobble it looks like about 1/8" deviation as it spins. I don't know how much it would take to produce the handling problems, but there it is.

What brand of tyre is it?

Very occasionally you get a bad tyre. I had an Avon that was defective many years ago. When I rang the fitters they politely took the P***.
Yet the tyre had strange ridges in the sidewall. They spoke with Avon. Turned out to be a moulding defect. Avon changed it. I politely took
the P*** out of the fitters! More recently the same fitters told me that they think the quality of manufacture is not as consistent as it was
due to out-sourcing.

When you have new tapered bearings the adjustment sets up precisely. If the bearings are worn you get a mushy adjustment - like you describe.
I would change those bearings - because your neck is worth it.

If you've got a local friend the quick and easy way to eliminate or confirm the wheel/tire as a culprit or contributor is to "substitute a known good part".

That is, swap the front wheel/tire from a Sportster riding buddy and go for a test ride. I mean it's pretty dead simple and quick to do and then you'll know.
