If you go strictly off of the manufactures specs, the Can Am belt would be better based on the materials it is built with. That being said, lots of people are running the Gates C12 belt and have not had any problems with it (Myself included). I personally think the OEM belt is way overpriced at $164 and you can get a C12 from vendors on the forum for as low as $79…..I would highly recommend you get a C12 and try for yourself. It will save you a bunch of money over the OEM and perform just as well….
