After a front tire renewal and machine balancing at my dealership a couple of weeks ago, I noticed a slight "hop" at high speed. Rather than take the bike back for tire rebalance or living with the annoyance, I ordered a Dyna Beads kit from InnovativeBalancing, LLC.
Wow!. Those little beads work wonders. After pulling off the lead rim weights and installing the beads (which must be done VERY slowly), all hint of instability is gone. My bike - a K75S - has never handled better. I've now ordered another kit for the rear tire and can't wait to install it.
