Acerbis Universal Footpeg Covers are a must have if you ride in a lot of muddy conditions. I have after market footpegs on my KTM-450XC-W and they fit just right. They were snug when installing them so I just sprayed a little WD-40 on the I.D. of the covers and that really helped to slide them on and then to position them. So far they have worked great. I will keep my eye on them to see if I get any cuts or tears on them as it is very rocky here in the Northeast.
