I first came across Dyna Beads at a vintage motorcycle event. I was intrigued enough to pick up a brochure, but I was not really enthusiastic enough about it to take the time to read it for a couple of weeks … but I’m glad I did. I haven’t tried them on a motorcycle yet, due to the fact that my machines are currently off the road (general inertia getting in the way, as usual), but now being impatient to see if Dyna Beads do what is claimed for them, I tried them on my car … and yes, they do. They really do. Super smooth.
