The thing is a beast. Way faster than it needs to be and ate up everything i threw at it. I was really cautious at first, just wanted to get used to the car and figure out its capabilities for a bit. The 1st night out we did a pretty technical trail from River Island to the Desert Bar road. Somehow I bent a mid radius arm on that run. The next morning I called Assault Industries and ordered a complete set of radius arms for the back. They showed up the next day and had it back running by mid afternoon. I took it out a bit that day...prob 30 or so miles to get used to it. Went out that night with the wife and ran up Osbourne Wash to Shea Rd and ran back along Shea Rd back toward Bradley Chevy and then back to the house. We ran along Shea about 60 or so MPH at times and I never hit anything that made me feel uncomfortable at all. I would come up on holes and back way off and hit them and barley feel it. As I got more comfortable I increased the speed and would literally float over holes. My wife's first words after we stopped after running a pretty used up section..."holy shit this thing is smooth, there is no way we could have gone that fast in the RZR". It worked flawless the rest of the weekend. My almost 3 year old loved it...it's his new race car. The 15 month old liked it but i need to figure out how to keep him from sliding down in his seat.
