yepThey're awesome! DO IT!!
no problems here, had it up to 130-140 and no shakes or any signs of something wrong.
Although it will turn you gas cap backwards...
I bought them to put in my tires this go around but didn't do it yet. I have since ridden my bike upwards of 90mph and no vibration with no beads or weights. I think I'm going to just let it be...
What are you guys running that you have not needed weight?
Ride On is a much better product that also is a tire sealant...
