Hi I have two questions; Does using the beads effect the tire warranty, How much do they cost? I currently have Metzler 880s on my 07 Mean Streak.
Some tire manufacturers are old-fashioned and out of touch when it comes to weight balancing so in those cases they will void the warranty for just about anything except looking at your tires so just check first to ensure they will not void your warranty. The operative word here is "SOME" and not ALL.
However, all major motorcycle tire manufacturers only mention references to liquid sealants used inside of tires for voiding their warranties and millions of people use the beads. Just check with your particular tire manufacturer or retailer about using Counteract or Dyna Beads in your tires but chances are in your favor that they will still honor the warranty if you use this dual dynamic-static balancing system.
Please NOTE that Counteract or Dyna Beads are NOT recommended for use in track/race tires. The inner liner on those tires is softer and subject to scrubbing wear from the beads particularly with the hard braking that is done during corner entries.
As for cost it averages around $40 standard for a bike (install included) at my shop and goes up from there depending on how much is used or needed. The cost is based on the size of a tire so the larger the tire, having a trike setup or darkside setup will use and cost more.
It costs about the same if you do it yourself and isn't hard to do but the beads are what cost you whether you do it yourself or buy from a dealer like me. However, if you have weights currently in place it will require their removal prior to bead conversion since you can NOT use both balancing systems. I also give extremely competitive pricing based on a person's area dealers but all dealers are required to start at a set retail price mandated by the company and the only additional charges would be labor or extra materials used above that if needed.
There is a relatively inexpensive small clear plastic bottle that is available for purchase and it can be reused indefinitely for future use. It has a long nosed inverse conical shaped tip for inserting the beads into the valve stem and it's very easy to install the beads. A relatively inexpensive special filtering type valve stem is then used in place of the ordinary stem since the new valve stem merely retains the beads inside of the tire. The old valve would get clogged with beads if you keep it in place. You do not have to repurchase and replace the special stem every time you use beads in the future unless it is damaged similar to the normal valves in use that fail and need replacement.
To check pressures simply ensure the stem is at least anywhere from 10 o'clock to 2 o'clock position and tap the stem to ensure all beads drop out of the stem area. Once you install the beads they will no longer be visible. They do make a low almost imperceptible sound when you first install and then ride to balance your tires but after that you shouldn't be able to hear them. If you leave a vehicle or bike sitting for a long amount of time the static charge that retains them in place inside of the tire will dissipate and all one has to do is drive the vehicle or bike again to rebalance. Once the beads are in place they are designed to stay in place due to static cling.
