Opinions on Dyna Beads for tire balance?

So, looking to put in a set of Bridgestone S21 tires and while looking at 90degree stems I ran across these Dyna Beads at Jake Wilson.

Read a bunch and it seems a lot like them, even some installers said good things. Only noted neg appears to be them sticking in valve-stems causing issues when adding air. (And making a mess when changing tires)

Many reviews were from big cruiser owners. Any BARFers have experience with Dyna Beads on a sport bike?

Voodoo exotic snake oil bs.

If it was legit then racers and manufacturers would be using it.

Balance your wheels the old fashioned proven boring way.

I believe they were invented for use in big rig trailer tires.
That should tell you all you need to know.

FYI, it's fairly easy to make a home made balancer setup with some wooden blocks, brackets, and decent ABEC rated bearings. I think I have <$10 in my set... Or go off and spend a few bucks on some - they're out there, from <$30 to Marc Parnes stuff that's in the hundreds.

You can easily balance to within a 1/4oz, which is more than adequate for anything a bike will do, Moto GP included. (If I recall, both WSBK and Moto GP still static / hand balance tires. If it's enough for them, it's certainly enough for me.)

I had several liter bikes that I changed my own tires on and never bothered to balance. It was never an issue but I rarely ever go over 120.

Just put a handful of 1/2" nuts in your tire next time you mount 'em. Should do the trick for a lot less dough. :party

I use them.

If what you're talking about are tiny ceramic beads, I'm using something similar right now. Bought it off Amazon for cheap. I ride my cbr about 700 miles a week, commuting, and I ride pretty hard. Do all my own maintenance, so balancing a tire isn't something I'm into. Before I changed this set of tires I had a pretty significant tail wobble, now it's smooth as butter. Is that the beads, the air pressure, swapping back to the stock exhaust, realigning the bike, I really don't know. I've got 4k since I put them in, and the bike vibrates less than it did. Ymmv. Running Michelin pilot power in the back, Michelin road 2 up front.

I’m guessing you changed the rear tire at the same time you installed the magic beads. Is it possible that a new tire is what made the difference? Just asking.

Oh totes! I ran the absolute shit out of those tires. Like I said, all I can attest to is that I have no wheel weights on my bike right now, and she acts balanced af. If it works for you, great, if not, hey, maybe I'm just lucky?

So less flippantly. For the first... 300 miles? after I installed the new tires with the beads when I'd hit potholes or debris at speed it would feel like the beads got loose or some shit. Idk. It absolutely settled down in the time since. There's a brutally torn up patch on 17 I hit every day, and she stays steady now.

How do I quantify an effect I can't see or effectively document? *Shrug*

I knew a guy that worked at a shop. He "had to" take an old gen VMax home one nigh to test ride it. He put new tires on it & for some reason decided to test out not balancing the tires. I think it was the front he said that was way out of balance on the balancer.

Said he never noticed much of a wobble until over 100 mph. Even then, nothing he felt worried about. Shrug. Moral of the story? Balance your tires, but don't stress about it (& don't spend good money on snake oil).
