The result is a smoother ride AND a better look - Dyna Beads eliminate the need for ugly lead crimped-on spoke or stick-on wheel weights on your rims. Unlike messy liquid balancing medias, Dyna Beads don't thicken or harden over time. When you need to repair a tire puncture they don't interfere with plugs or patches.

DynaBeads can be used in tubed or tubeless tires, and they also work for scooters, ATVs, or automobiles, and other tires. Contact us by phone if you have non-motorcycle application.

Dyna Beads dynamically balance tires on the move, resulting in a smooth ride that lasts the life of your tire. In fact, your tire will remain perfectly balanced until replaced. By contrast, a tire balanced "the old fashioned way" with lead weights can become unbalanced in as little as a thousand miles. You'll know when that happens because the handlebars start to buzz, and if you look at the front tire (while it's spinning on the road) you'll see it vibrating. That's because the wheel is no longer in balance.  As rubber wears, the wheel gradually becomes unbalanced.

So how do Dyna Beads work? Imagine this scenario - you have a washing machine going thru the spin cycle with 3 pairs of blue jeans. As long as there's water in the drum, the machine spins in a perfectly balanced fashion, but as soon as the water drains out, the machine starts that old thump-thump-thumping noise because the load is unbalanced. Pour back some water (or in the case of a motorcycle tire add some Dyna Beads) and the load re-balances itself.

A more technical explanation goes something like this: The tire/wheel/ axle assembly is constantly spinning in an elliptical motion due to the inperfections inherent in tire and wheel manufacturing. If the wheel was perfectly balanced there would be no vibration at the axle, but because no tire or rim is perfectly balanced, you must add lead weights to smooth out the spin. An unbalanced tire bounces up and down because the suspension is storing and releasing energy each time the tire spins thru a rotation. It's a complicated ballet between the various components, with the heaviest point of the wheel pulling the axle off-center. Add balancing media (Dyna Beads) to the inside of the tire and the laws of physics will distribute the beads to a point opposite the heavy point of the tire/wheel asssembly, and the tire will return to a neutral (balanced) spinning point. The tire stops bouncing and any vibration goes away. Whew, enough technospeak! 

For the adventuresome riders who change their own tires, and for those who travel to the far corners of the world and have to change their tires in the field, Dyna Beads provide a perfect solution to "field balancing" tires when there's no other method of balancing available. You won't have to rely on the "old red dot at the valve stem" method of tire balancing, hoping that the light spot of the tire will offset the heavy point of the rim (it seldom does).  

So how many Dyna Beads do you need in your motorcycle tire? 
    Smaller bikes require 1 ounce in both the front and rear tires... order DB-2
    Medium-to-large bikes require 1 ounce in the front and 2 ounces in the rear... order DB-3
    Large bikes (Gold Wings etc) require 2 ounces in front and rear...  Order DB-4

When in doubt, order the "next size up".  Additional DynaBeads inside the tire won't hurt anything, they'll just help keep the tire balanced and they'll automatically redistribute within the tire, based on the natural unbalance of your tire.  By contrast, not having enough Dyna Beads can result in an unbalanced tire because there won't be enough of them to offset the wheel imbalance.

** Here's a recent testimonial posted on a web forum.  We didn't solicit these comments, they're straight from the customer:

“There has been quite a bit of discussion on the GS list about DynaBeads, and when I first saw them I was smelling “snake oil”.  But I decided to get some and test them out.  I put them in a worn, cupped, out of balance TKC-80 mounted on an '89 R100GS.  After several thousand miles in seven states the tire has certainly seen better days.

To begin the test, I put 1 oz. in thru the valve stem without removing the lead weights.  I rode about 150 miles over various terrain, including some of Lower Alabama's finest dirt roads.  It rode like a newly balanced wheel.  Speeds varied from 20-40 on the dirt, and up to 80-ish on the pavement.  I was impressed.  Next, I chiseled off the weights and rode another 150-ish miles.  This time I didn't do any dirt, but speeds topped out at 83.4 mph.  It felt exactly the same as the previous ride.  I'm sold!

That's all there is to it! As soon as the wheel starts to spin, Dyna Beads will dynamically and automatically re-balance the tire.  When the wheel stops spinning the beads drop to the lowest point of the tire and wait for the next rotation and balancing cycle.
