Just wondering from those who have the Razr's for their xx, how is the clean out when you get in some really sticky mud? The mud I find where I ride is so sticky that even when you're in it spinning with plenty of ground clearance, the stock tires will be so packed that no tread is visible. They'll look like a slick tire. With no tread grabbing, you don't go anywhere. How do the Razr's clean out? I'm ordering a set tomorrow from a local dealer. I'm getting them for $79 each!!
