I have an 850 Polaris touring ( 2 up model) and have the Camoplast T4S model tracks for it. I only used them one time and am selling them but for that one time, because I was in powder snow, I didn’t get soaked and my undercarriage, that is the tracks themselves, didn’t get plugged up with snow. The other guy I was riding with who was on an 800 Can Am and had a different brand of tracks didn’t have any trouble either. We rode for 2 days and went through only a little more fuel than if we were riding with tires and bucking a foot to 15″ of snow. But we were able to go pretty much any where we wanted to go. The snow was probably 6′ deep with 1 1/2′ of powder. We had a blast. We went back to camp at the end of each day but other than gas them up, we didn’t do anything to prepare for the next days outing.
