Hey everybody, our new 2025 Polaris RZR Pro R4 Ultimate has been under the knife getting a ton of upgrades, getting it ready for all types of riding. We've got a detailed walkaround video—let's get into it!

Hey everybody, it's Nick Olsen. Welcome back to the channel! We take this RZR all over the place. We've owned it for a little over a month, and we've already taken it to Sand Hollow for some rock crawling, been to Glamis a couple of times for duning, and now we're taking it on a several-hundred-mile Arizona Peace Trail ride. It's kind of similar to Baja-style riding.

If you guys are new to the channel, that's what we're about—exploring all different types of riding. Let's start off talking about the parts breakdown to make sure this car performs at its best in all environments.
