I noticed that the ITP C series wheels have a sticker on them stating not for high performance use. I was curious if anyone had broke any of these wheels or had any other problems with them ?

 

I noticed the same thing!!! But, I have 2 friends that have a set on a trx520r and a yfz470 and they havent had any problems with them. They do a lot of hard/fast trail riding and not much MX. They probably have that on there as a precaution so if anything does happen ITP wont be held accountable........JMO
