Some call it feisty. Others call it beast. And Polaris itself calls it the best RZR ever. There’s no doubt that this machine is cutting edge, and it’s praise and accolades from both riders and institutions alike give it a lot to live up to. It won the title of Vehicle of the Year for 2019 by SEMA Powersports, and those who have driven it will seldom disagree. Is this truly the best UTV on the market, and does it have any flaws? Well we looked into it, and here are our findings.
Polaris RZR Pro XP Overview
Many riders of the Polaris RZR Trail and Rock edition have decided to switch to the Polaris RZR Pro XP, while riders who have yet to switch are wondering if this vehicle is truly as capable as everyone says it is. From the riders we’ve spoken to who have switched the Pro XP RZR, the difference is huge. In terms of rock crawling, the higher gearing makes the Pro XP suboptimal. But what it leaves on the table with higher gearing, it makes up for with sheer speed. That being said, although the gearing is not near as low as the Rocks and Trails RZR, its quite a bit better than than the old RZR Turbo S edition.
The steering on the Pro XP is quicker than other RZRs, and the turning radius is similar to that of the Rs1. And while it is built for speed and agility on the trials and tracks, a few adjustments and modifications can make it perform better when rock crawling.By adding some true dual rate springs, raising the ride height a little, and throwing on 32” tires, you’ll be nearly unstoppable on the rocks and have a machine that is comparable to the T&S RZR.
Unlike the RZR Turbo S, the RZR Pro XP doesn’t have the Dynamix Active Suspension Technology. But ask most Pro XP owners and they’ll tell you that the Pro is legit. It rides incredibly smooth and is so predictable and nimble. It's way more comfortable than other side-by-sides as well, with the power coming on so much better than, say, the Turbo S — and it just pulls harder.
If you ride mostly trails and fire roads, you’ll find the Pro XP to be incredible. Both at wide open throttle and out of the hole the Pro XP is a white knuckle grabbing beast. Its raw power and acceleration is just breathtaking. Add a few aftermarket accessories and it’s simply unmatched. It’s no wonder the Polaris RZR Pro XP won its class at the Baja 1000.
Criticism Of The RZR Pro XP
With all the praise we’ve been heaping on this great side-by-side, it’s not fair to overlook it’s cons — yes there are cons. One thing riders of the RZR Pro XP dislike are the doors and holes behind the seats in the cab where mud gets flung in from the rear tire. To combat this, lower door inserts and a front window help a ton in mitigating the amount of mud and debris that gets thrown into the cab.
The clutching is another issue that has only recently been figured out. Riders of the older versions of the Pro XP — even after spending quite a bit on aftermarket parts — still suffer from shifting slippage and excessive ware on the belt. After spending so much on a machine like the RZR Pro XP, it is disheartening, to say the least, to have to spend more to fix clutching issues. Over-shift and belt slippage can be fixed with an Aftermarket Assassin's tune and a stiffer secondary spring.
Without tearing your clutches apart, there is a way to tell if your machine needs a clutch upgrade. Have a look at the build date on the sticker on your frame to see when your machine was manufactured. Your dealer can also tell you via the VIN. If your rig was built before October 7th, 2019, you’re going to need the heavier secondary spring. If was built after the seventh, you should be good to go.
The motor in the new XP Pro is very similar to the old XP turbo. A primary difference being that it has larger head bolts and an auto coolant bleeding system. This makes it an absolute rocket. An RZR Pro XP running on E85 with a tune from a company like Aftermarket Assassins can finish off at 215 RWHP — whereas the stock RHWP is between 145 and 150. Thats nearly a 60 RWHP gain in power over factory with a waste gate adjustment, 1200cc injectors, and all of their other bolt on’s. This goes to show that the potential for the Pro XP is vast, and by making the stock machine so powerful, the only way you can go with aftermarket accessories and adjustments is up!
