Brake Vibration
So, my latest go around with the dealer experts.
At the end of September went on a ride to Las Vegas, via Death Valley, on the way to the valley floor from the West approach you drop down into the Panamint valley before you get to Death Valley proper. There are some really nice curves going into Panamint on the downgrade. That is when I noticed the entire front of the bike shaking whenever I applied the front brakes. So... I have finally gotten it up to the dealer this past week so they can check it out. Here is what they found was causing the vibration... They found the rotors are within factory run-out specifications, so they installed (replaced) front wheel bearings as they have decided that the bearings are the culprit in causing the vibration under braking. But they are going to test ride it some more and see if the vibration is gone... Now, I failed to mention to them that I took an advanced riders course in which during the "panic" braking portions I was smelling roasted brake pad smells, I didn't want to get into the blame game of something along the lines of, I had failed to keep the tires inflated with factory approved air. In my 30 some years of working on the four wheel vehicles I never ran into a wheel bearing that caused a vibration under brake application, there were the few bearings that were worn or sloppy enough to allow the rotor(s) to push the pads back enough to give the driver the feeling of no brakes, until the pedal was pumped once or twice and the pads were pushed back to close contact with the rotor. So Harley's must have some pretty unique wheel bearings that are smooth at high road speeds, but cause vibration under brake application... Sigh...

Yeah, maybe your fork tubes are floppin' around in the triple tree.
You need a fork brace. Or a wrench. Yeah, that's it. Wiper fluid is depleted.

Probably overheated and warped the rotors.

Hummm, maybe possibly...
But the Rushmore platform has "full" floating rotors, the bolt is tightened through a "sleeve" spacer to attach them to the hub of the wheel. Also, yes, does have linked ABS, but at lower speeds are un-linked. Also I did notice some ABS cycling during the advanced course, there was a bit of a pavement bump just prior to where you were panic stopping, so the rear tire would hop and the ABS would cycle and when the rear tire hit back onto the ground I was being told that I was locking the rear wheel, I explained that the ABS was in cycle and when the tire contacted the ground there was probably a bit of tire scrub noise upon touch down when it had to start "rolling" again.

Well picked the kitten up today, a quick blast down the road and lightly applying the front brakes confirms they are not fixed!
Anything above 40 MPH, just enough pressure on the front brakes to feel that they are starting to grab the rotor. And... It instantly feels like the road surface becomes very rough and the windscreen starts to shake and shimmy... Beside them not fixing the brake shimmy shake, I now have a collection of oily hand prints on the forks, front fender and the exhaust heat shields and both muffler bodies. I can't wait for the survey e-mail... *

I wouldn't wait.
Send a friendly note to MOCO and see if you get a response.

Putting a full floating rear rotor on my '06 really improved the brake reaction time...

Brake Vibration
I wouldn't fix it on my dime yet, I would call HD and complain that a safety issue was not repaired and I expect satisfaction
