hey Kinarfi Ive been looking at the rzr a lot and friends of mine have polaris quads wich are belt drive very similar set up I guess that can be kinda a common thing with them, specialy if your going in the water mud or big climbs with lots of wieght. Last time i went out my buddy was on his 4x4 polaris quad hammered the hell out of it all day then when we were just cruising home he lost the belt.
