    Hello, I just bought some fenders for my bike, and they vibrate my bike alot at high rpms. I'm wondering if anyone knows of a way to stop the vibrations, or at least dampen them a bit in my fenders? It doesn't seem like I can tighten anything or put any other brackets on, or maybe another bracket at the ends of the fenders would work? Any suggestions? Thank you. :)

    Here's some more pictures, to give you a better idea of what's holding the fenders on.

    i run fenders on all my bikes. it looks like (to me, anyway) that your fender struts are pretty cheesy. plus, they've got a lot of extra parts to rattle around. i usually use WALD fenders, that are heavy duty, and have been around for a hundred years. they still make them, along with struts and other brackets.

    here's a link to a place: Fender Parts | BikepartsUSA.

    i've heard of people using undercoating spray paint on the insides of them, too. i think i'm gonna try that out on my next one.

    just make sure they don't come loose, or you're OTB.

    If you must use fenders, use GOOP on and around all brackets...very strong, i also use Goop on the motor mounts and around the mount bolts after install...great product...strong and flexible...Dennis

    These fenders were the best ones the pro shop had there. They were $50! They seem to have cured themselves though, I no longer have fender vibration, and I didn't do anything. lol. So I guess it's all good. I keep checking all the fasteners, nothin's coming loose. I'm curious how the vibs stopped, but oh well I guess! lol, my bike doesn't vibrate much, so I don't think I have to worry too much. I'll always check them though. I routinely check everything now, since I have alot to inspect. lol. Thanks to everyone for your help! :)

    I got the blue ones at canadian tire, and the red ones at walmart. I still have two more power ports to use, so I'll be putting even more lights. I probably won't run them all at once, but I will have options for different lighting combinations. :) Here is my Neon thread. :) http://motorbicycling.com/f26/neons-11686.html

    Use some adhesive backed weather strip inside the fenders...helps considerably.

    Got a car stereo shop nearby? If so stop by and ask if they'll let you have scraps of Dynamat. Very dense, self adhesive and it'll easily conform to the inside of your fender.
