My vote was FAILED before 5k miles. Around 3k miles I first noticed it. I've never tried to wheelie or anything outside of normal everyday commuting.

I've rode over 6,000 miles in less than 10 months.

Between 30-60mph coasting, the death wobble is ALL too real.

At exactly 6,001 miles I switched to DR II's.

Now, when I'm at highway speed, my front handlebars have SO much feedback my arms shake.

The input from the front end of the bike is much more prominent now.

It seems the new tires are now bringing out this issue even more.

Some random mechanics at Del-Amo told me it's NOT the head bearing, it was because the tire was soooo bad. FALSE.

So it looks like if it's going to fail then its going to happen pretty quick.
That's usually how it works, called the bathtub curve in engineering. A part usually either has infant mortality or fails due to (old) age. Though the concept does seem rather obvious when written down!

Even if theyre not bad its probably worth swapping to tapered bearings anyway. They feel much better that stock.

It seems like if you’re going to have a wobble issue when riding hands-free, chances are it will happen before you hit 5,000 miles.

My bars wobble when I'm in gear and let go of the bars while decelerating... Is this the issue with the head bearings and if so, do I need to replace it and where can I get better ones that'll fix this?

Going through all the head shake problems at the moment and jumping through all of Kawasaki's loop holes to get things taken care of under warranty. The bike is covered through most of January 2018. They want both tires replaced which the front will be done tomorrow, the rear was done last week and made absolutely no difference. I'm hoping the front tire is the problem but don't hold a lot of hope there, the tire is still in good shape by looking at it, the rear was close to the to the wear bars. Right now the bike has just a tick over 5000 miles on it.

Just a bit over 42,000 miles my steering started giving me a thumping feeling, lifted my moto up and noticed the steering would settle right at the middle instead of turning smoothly. I do about 90% freeway riding and 10% street. About to replace the bearings in a few days when the new ones arrive but these stock bearings had a good life with me.

Could be tires or wheel alignment as well but before spending any money, check your bearing. If you're not sure how, watch this video from Ari Henning on youtube. It won't let me post a link because I'm new to the forum.
