Just got these in and this is the third set of tires I have us these on. Very happy with the out come. Good milages.

I had these on my previous wing & was very pleased with them, so will be installing them in spring b4 the 2012 riding season.
Have them in my 08 Raider also & not a bit of problems to date.

Have had these on my 1500 for over a year now. While on a trip through Arizona last year I lost a ( or some ) front wheel weights. The bike shook badly at highway speeds. Put in the Dyna Beads as a "quick fix". Never did have the tire rebalanced as the Dyna Beads have taken care of it just fine. 10K miles later I think I well try them on the next set of tires I put on bike.

My initial review was on 8/2/2009 (still there!), and I thought I should update.

I have had Metzlers my whole biking life, and yes, they have a stigma of cupping and trashing quickly. Most I ever got was 10,000+, but I desire their stickiness. I only make this point, to make another. I am on the same set of Metzlers I had mounted at my 8/2009 post. No weights. I now have 14,000+ miles on this set and they are showing MINIMAL cupping (and I mean minimal). They are silky smooth at all speeds, and the tread is still very deep. I have no doubt they have 5,000 to 7,000 miles left to go. My theory is a combination of the beads and the All Balls tapered bearings (a MUST on our bikes) have lengthened the life of the tires. That, or I was blessed with a surprise from the Metlzer Tire Gods. I doubt the latter. Oh, and I have had racetech springs since 2006.

Not to be long on this, but do I believe the beads are an easy and very inexpensive way to keep our tires balanced through their life.

The beads seem to work just as described.
I installed them in a 2009 Goldwing/Roadsmith Trike.
I put 2 ounces in the front tire and 3 ounces in the rear tires.
