Was happening to me, very mildly. And yes, after I shimmed down the front bearing, it was gone. It's supposed to be a dresser only issue...

Rear tire pressure was at 40, checked when I got home. Front was high but don't think that contributed to it.
I've always been under the impression that the bagger wobble was close to, if not cured, when HD upgraded the frame in '09.

My Sporty was another matter. It was possible on that bike to hit a series of fast stutter bumps at just the right speed and bump spacing and have the front wheel jump from lock to lock, yanking the bars right out of your hands! Fun-NOT!
I've experienced that on a Sportster. Coming back from Laconia heading back down to Cape Cod. It was somewhere between late night and early morning and I was buzzing down RT93 half awake. I hit a series of bumps like that crossing and overpass and the bars came out of my hands for a second before I got the bars back under control. Talk about a pucker moment.

Gunslingertom, yes....you are correct. It was time to move on. Really diggin' this Softail. Can't wait for the apes!

Now I have a question. Has anyone on this board ever heard of this problem about other bike manufactures? Has anyone heard of a Goldwing wobble, an M109 shimmy, or a Ducati dance? Just wondering if this is a Harley issue or is it a universal motorcycle problem? I got to figure that if a Hayabusa did this at 160 or so miles per hour there would be some little Japanese engineer slicing his belly open just on principle.

I'm blown away! At 47 and riding scoots since I was 12, I have never seen or heard of this. Seems almost impossible to have an engineering flaw like this.
Bikerlaw, the vid you posted really drives it home.
Time to bust out the bamboo sword so it hurst more.

Well, she sure is purty. Congrats on the new ride.

I've ridden and owned ton of vintage European bikes and never experienced this. I have also had my share of Jap bikes and still nothing. Never owned a Jap cruiser though.
So I've never experienced this phenomenon on anything, and still not my bagger.

Waaay back in a day and old Czech Jawa 350 did that to me. The rear bushings were probably worn from sidecar use (here you go, similarity with dressers' rubber suspension) and I made the matter worse by pouring some crap into the rear shocks. I flew over the handlebars. Still have a road-rush scar on my wrist

I had the wobble on a Suzuki GS 1100 I used to own a long time ago.

I had an 09, and it was better, but not cured. The problem is yaw, without the 3rd link keeping the rear swingarm and the rear of the transmisson straight and true with the front of the engine you get a rear yaw. Or rear steer, you really have to push it to get it to happen. Usually above 80mph and laid over, the longer the turn, the more likely it is to appear. The "Trakula" kit will all but eliminate the "rear steer" issue, and even better is you do the late model swingarm ugrade.

Coming from the mountains, and having before and after the third link experience on a 2005 Road King DD.......it is WORTH the cost of the upgrade. I will be doing my 89 soon.

I had "wobble" on my 1979 wing and my 78 CB750K.....it was cured by a steering damper on the 78 and I never got it to go away on the wing. I believe that its mainly an issue with "older" designs.......like the one our bikes are based on. It can be cured with a 3rd stabilizer, like Eric designed into the Buells
