I've run the Polaris wheels on my Viper for over 7,000 miles, my 97 XTC for 4,000 miles. Installed in my Attak at 553 miles (when I bought it) and pulled the skid with 3200 miles and the original hyfax that were on the sled when I purchased it. Didn't machine any mounts, just blue loctite and tightened them down. No delaminating wheels, although I did replace all the beaings before my first trip this season.The 1.25 Predator that I installed at the same time looked like new. No burnt or missing clips, no melted hyfax coating the clips. No rumbling when riding. This is the EASIEST mod you can do to increase hyfax life. I am a LARGE guy and don't baby my machine! Don't agonize over it. Install Doo or Polaris wheels and RIDE!!
