I have used dyna beads in my Harley tires for several years. I tried them initially because I hated sticking weights on my chrome wheels. They worked great for me and my Harley is much smoother (always going to have some engine vibration, of course).
The beads work better for narrow tires, however. If your have a lateral imbalance (need weights different on each side of wheel) the beads don't correct for that. So, I have my tires balanced the conventional way first and then add the beads while leaving the weights in place. This has worked well for me and provided a very nice balance in my opinion. I'm over 50k on my original KO2's and may get 60k from the look of the tire tread. Always rotated ever 5k.
