I purchased a 2008 Vector with 107 miles. My first non Arctic Cat since 1976. So here is the problem. The hyfax seem to wear quickly. I put a new set on and rode in good snow and trails and 400 miles later the are 1/2 shot. The leading edge or front are perfect but the flat surface of the rails are in bad shape. Do I have the track too loose or is this a Yamaha issue. I do see they have a carbon fiber set of hyfax availabe that they claim 5000 miles of wear. Never had this problem with cats. All comments welcome. Thanks.
