OK my seasoned friends. What the hell is this all about?
I don't think I have ever felt this on my scoot, but I'm on an older and maybe stiffer '99.

I'm interested in the comments. Great video.. I've experienced it once on my Wide Glide. But, I, like the video, was under power(maybe more than needed) in a turn. It appears that the rear wheel is tracking differently than the front due to the turn, load, and power being applied...It's probably due to the suspension "give" that the stabilizers, everyone recomends, are designed to address..

Also interested in replies as my Softail "wallows" on fast left hand bends. Does not appear to be as bad on right hand ones................

Cool video.

I have been told that when you get the death wobble the first thing to check is wheel bearings.

The "death wobble" is a bagger issue only as far as I know.
It seems to be a problem only on high speed wide sweeping right turns. I've never experienced myself and I live in the Southern Missouri Ozarks where twisties are pretty common.
Personally, I think it's driver error, but maybe I'm wrong. Again, I've never experienced it. Seems the best cure is to go into right corners at or close to the posted speed limit. I say that because the ONLY time you ever hear about it is when the rider is going 25+ over the posted speed limit.

I've never experienced that on a Softail. I'll admit the Softail is not to best cornering bike out there, but I've never felt anything like that when pushing it.

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!

Never experienced that.Could it be from excess weight on the rear of the bike (police radio and such) and the sidewalls aren't up to the task?

That is what I would think because that is what it looks like.
But supposedly this is a Highway Patrol test run and one would think that they would get the tire type right. Hell, it would have to be really heavy to get that kind of action. Now iI'm thinking it looks like low air pressure... Can't be.

Whoa, no no no no no. It is a HUGE issue on Dyna's as well. So much so that the Dyna forum sponsor IS True Track. I had it big time on my Low Rider and many Dyna owners complain insensately about it. For me, new tires, motor mounts and a True stabilizer was what what it took to square the bike away.
