I use them and have no problems. When I had the bike dynoed Doc said a couple times the bike jump around at high rpm, that hasn't happened while riding.. also, that could have been the cheap shocks harley uses. Over 8k on them and I've seen no problems.

 

I've used them in 2 bikes without issue

Here is my 2 cents!
The principle is all tires are spinning on ball bearings, and nothing will roll smoother than a bearing at any speed.
A balanced tire with dead weight will match the tire rotation with the bearing at ANY speed. The Dyna beads, or other beads will NOT balance the tire at certain speed, especially at low speed, and it requires AN AMOUNT OF TIME for the beads to distribute, or concentrate at a "right location" to balance the rotation.
You can see in the "demo".
A weight will NOT come off the rim, if there is a proper preparation the bonding surfaces.

Here is an article from the company in the above post, which has confirmed my theory: beads cannot comparing to the traditional balance method.

Use whatever method that make you feel good, but to be real. You know what to use!

 

I have used them in three bikes now and I think they are the finest thing since bubble gum. Will never go back to static weights. What the previous poster says about them not working at low speeds is true but is of no consequence as you will never notice it at low speeds.

 

Have them and will continue to use them.

 

I used Dynabeads in my last 3 sets of tires on my previous bike. I changed my own tires and never saw beads embedded in the tire casing. I plan to go back to using them when I change out the original equipment tires on my new bike.

 

I've been using and recycling them. can't complain... much... tires and ride seem fine. Bike... another story.

And no, the dyno beads are not somehow causing a special scientific vibration harmonic that is running through my bike destroying the rest of it. It's just a problem child at this point.
