Ok, I know about and have used Dyna Beads in the past and will be putting them in the current new tire, but I was wondering since II discovered that the last tire change even though I requested the beads be transfered that there were no beads when the tire was changed last week. This got me to looking for other alternatives and dealers (local) for dyna beads or others. During the process I found www.centramatic.com and their permenant balancing system for motorcycles. It mounts a unit behind the rotor that has an active balancing system in it. Now these are more money then the dyna beads but they are install and forget about them and not likely to be "lost" during a tire replacement. So my question to the forum is has anyone ever tired these and if so what do you think? Mike I've mailed them and they say the model mhd 200-202 would be right for my 08 K-9, they also come with a 30 day money back gauruntee from authorized dealers.
