Very interesting Cat! I asked that same exact question not a month ago and got refered to their rules which clearly state the RZR is restricted to the green trails only!
I got hammered by the bunch at PRC over it and have not posted there since except for threads I was immersed in.
I even cancelled a long planned trip to the HM trails because I would be holding my buddies back who love to find the hardest trails that I would not be legal on. Here at home they have a tough time following me in my RZR!
What really Ps me Off is they are so slow to recognize and approve a good machine and can't just let riders decide for themselves just how much trouble and expense they are willing to take.
Think about it for a minute. I know guys who have some real well built full sized rangers that will do just fine with them behind the wheel. I also know some guys who have other approved machines who can't drive well enough to get over a stump or up a steep grade!
I think it has nothing to do with the machine and everything to do with who is behind the wheel!
Just because a guy has a dirt bike doesn't mean he can drive it in the dirt!
All these regulations and width rules serve only a bunch of idiots who have no clue how to ride or get past obsticles and thats what off road driving is all about.
I'm expecting the next hurdle to be " Those over 50 are not approved on this trail " ! With my middle finger pointing upwards!
