In my experience the only parts that fail - I believe it's vibration - are the bolts that hold the the two fitted pieces/clamps directly onto each side of the handlebar. They are the largest bolts included in the hardware. The trouble is that if that happens on the road - happened to me twice - you are likely to loose the the clamps which, unlike the bolts, can not be found in any hardware store. I went to a specialty fastener store and bought - what I was told - higher quality/strength bolts. I change them out every couple of thousand miles - or before a trip - hopefully before they fail. I also zip tied the clamps so that if the bolts again fail they will hold together and not hit the road. Looks shade tree but whatever. Bogdan> > > I got my cf 30 shield yesterday.

I am guessing that only one side fails at a time, so the windshield doesnt fly off in your face! I can see how if one side failed though, it might load up the other side and cause it to fail too. Have you ever had any close calls because of this? I'm thinking maybe of drilling some holes in the windshield vertical mount bars below where they mount on the bar clamp, and safety wire loop it to the handlebars. If you safety wired both sides, only one would fail at a time. I can see now why it fails. The entire windshield force puts a levered bending moment on those handlebar clamp bolts. That must be the reason that they say this shield is not rated for touring cause the fatigue looks like it will get those bolts every time. I'm going to have to figure a way to relieve the stress on those bolts. Any ideas out there ?> not hit the road. Looks shade tree but whatever. > > Bogdan
In my experience one side fails at a time. The situation was not dangerous. It was inconvenient; last time this happened I was in the state of Coahuila in Mexico. Since I went to the better bolts and have been changing out the bolts I've had no problems.

Sounds interesting. I'll waiting to see how hard it is to do and how it works out. I also like the shield. Yours sounds like a fix and forget about solution.
