Iam going to take a guess RICH is because needs alot more HP for all the extra weight being carried,or geared totaly different especially for those TREADS but still makes it avalialbe to get the whole family playing and thats what POLARIS wanted to achieve
If it made it through that mud hole, to me it still looks like fun, now you can get mre people dirty at the same tiime. Being able to take the family out on the trails in one vehucle makes up for any power loss.
Its a different fun, my 08 rzr had a 4" Catvos lift and 31" outlaws, clutch kit and LTE w/a programmer. I built it to play in the mud.
The 4 is built for the entire family to have fun. I actually enjoy this more d/t the fact we can all ride together at one time.
The only real diff b/t the two is the obvious lenght but that is actually an advantage, I can climb out of creek beds that the other RZR's have diffictulty. The newness hasn't worn off enough yet for me to take it to the limits so I still baby her to a degree. Now once the 6 mos warranty is over, Its getting snorkles, clutch kit and probably exhaust and a programmer.
