This may be a stupid question but....

In lieu of spending $15 on Dyna Beads, I wonder how slipping about 10 or 15 BB's from a BB gun in the tire before mounting would work?

I personally don't see much of a problem... Do you?
 
I had never heard of dyna beads so I looked them up online. I can't quite wrap my brain around how, exactly, the beads find themselves opposite the heavy spots. I did notice that in the pictures showing you how to intall them, the wheel in the photo had wheel weights on it.

I say drop some bb's in you tire and report back.
 
You would think that the beads would be attracted to the heavy spot and make the problem worse.

I would vote for a nice static balance.
 
MCN studied Dyna Beads extensively and concluded what most of us already suspected: They're a gimmick and do not work for motorcycles.

I'd rather run no balance weights at all than pour a bunch of flotsam in there.
 
Doing the tire change myself to save 50 bucks.

A little research on Dyna beads will show they do in fact work. Physics or something :rolleyes

I did some more research and it seems like some people are using airsoft pellets. Might just give those a try.

Interesting.. I'm curious to hear from people on this forum who have tried them. There is quite a bit of positive reviews for them on other motorcycle forums across the web.

Whatever. You initially wondered if your question was stupid, then you roll your eyes at me for an informed and thoughtful reply? I don't think you're looking for honest input at all; maybe you need affirmation for your clever choice?

I trust MCN's report far and above the bullshit "research" you'll find online. That is why they studied them: There was a lot of curious buzz about them back then (over 5 years back), and their readers requested it. They were thorough, they revealed Dynabeads as inferior to static or dynamic balancing, they allowed Dynabeads representatives to respond and rebut, and they put them in their place with scientific logic.

And for all who offer anecdotal claims that Dynabeads work very well in their motorbike wheels, I'll bet dollars to BBs those guys would have come to the same conclusive mindset with no weights or beads at all, especially if they were placeboed into thinking Dynabeads were installed when they really weren't. These are the same guys who tape magnets to their fuel lines and report mystical, 10-20% bumps in both HP and MPG.

But you go ahead and try them, let us know how they work out.

My apologies, I didn't mean for the roll eyes to come across in a negative way, nor was it directed at you. Just a general bit of sarcasm towards those who don't believe they work.

Of course, I haven't tried them yet so I can't really say they do work. What I have found though is more positive reviews for them than negative.

I'm probably going to end up trying airsoft pellets as I have some at home. I will definitely post the results!
 
Yeah i dont believe they work.


Here is an excerpt from an email sent from the guy at no mar tire changers.


Dean, Dynabeads do not work on motorcycle tires despite their faithful followers opinions. They can't work and it has been proven in published tests in Motorcycle Consumer News a few years ago. **What happens to the beads under hard acceleration? **What happens to the beads under Hard Stopping and re-acceleration? **What happens to the beads when there is a heavy spot in the tire that elongates the tire. They certainly don't move to the opposite side. **Have you ever tried to install a tire without tire lube? **Tests prove that there is better results with no beads and no weights than adding the beads. **It is faster and less frustrating using a static balancer than feeding the beads through your valve stem. **If they actually worked, or even worked better, Don't you think they would be the preferred way to balance a wheel? The beads were designed for non-pliable, non high speed rated Tractor Trailer tires which have a square tread design. (Which probably don't matter much anyway). Trailer companies generally do not balance trailer tires. It would be equivalent to balancing an ATV tire or a kids dirt bike tire. Many people want to believe the beads work like a "Magical Goo" spreading themselves amongst the tire and evening everything out. The only basis for this "wish" is the hope of an "easier softer way", instead of learning something new. There should not be any mystery in wheel balancing after kindergarten. It is the same principle as the "Teeter Totter". If two kids of equal weight are on each end they balance. If one kid is fatter, then he sinks to the ground. The fat kid won't lose weight (we've seen that before)so we need to add some weights to the skinny kid's side to get it to balance. It is the same with a wheel and tire on a static balancer. Heavy spot sinks to the bottom. Add weights to the top. Turn it a little and adjust the amount of weight until it will not move on it's own. Pro-Race teams have been using this method for years. It is fast, simple, and perfect. Steve.



If you gonna come back with results dont just say "they feel great!" Get some data. Have them dynamically balanced and report the outcome.

Mix some voodoo science with some anonymous positive reviews on the interwebs and viola, the result is the cult of Dynabeads.

Now you can't afford Dynabeads so instead you're going to load the inside of your tire with airsoft pellets? :facepalm

Any reason for not using the tried and true conventional method of balancing your wheels?

Oh wait, what was the question?

The internets told him so.

I've been using airsoft BBs in my last 20+ motorcycle tires. get the biggest/heaviest one they make. the only downside is you have to put them in before you close up the 2nd tire bead.

do BB/dynabeads work? don't know but I've had zero balance issues.
 
Ok, "the list"

1) countersteering
2) Oil type/weight
3) Harley's
4) Dyna beads
5) High beams all the time
6) Tire pressure
7) Gasoline octane
8) rear brake usage

surely I've missed a couple :dunno
 
Been using Dyna Beads in my touring ST3 and one of the race bikes. I too was puzzled about how and why they work so thought I'd try them. So far they work as advertised. They were first developed (in super large size ) for truck tires. I'm halfway through the set of tires on the ST and so far so good. The race bike not so much as you chew tires up each race and lose the little balls in pit lane! (hey, my balls fell out!)
Cheers all.
