Does going slow with XP Pro 4 break it?

I had a dealer tell me to buy the XP 1000 over the XP Pro 4 this past weekend if we didn’t keep it over 40 mph most of the time because it will break belts/parts inside all the time.

We spend about 90% of our time riding trails up in Island Park and with younger kids do keep it 25-35 mph most of the time right now. We also hit sand dunes 1-2x a year.

I really like the structural/seat upgrades of you get on the Pro but don’t want to get it if I really will be breaking things all the time from slower riding.

Last week I did three days on the Rubicon trail with 36 other UTVs of all kinds & types. I followed a new 4 seat XP Pro and a 4 seat Turbo most of the time. The average speed on the trail was 3.5mph and of course a ton of it was crawling from one boulder to another & up ledges etc. I didn't see one person change a belt in three days or break a thing. I heard a KRX lost his front diff & there were a couple bent tie rods & radius rods from landing on rocks, but no internals broke. I had a power steering fuse blow when I hit one of a thousand rocks just wrong with my tire, but that was a quick fix. I was amazed at how the supposedly high speed, higher geared Rzrs handled the trail. I was able to crawl when they used more gas to get over some obstacles, but they made it just fine. Almost all were running 32" tires or bigger and most did not have clutch kits or aftermarket clutches.

Yeah, like on a Jeep I wouldn't do it all the time, but I upgraded ball joints, tie rods, axles, skid plate, added bead locks & new tires, and luckily already had High Lifter radius rods & a arms and rocker panels. If you go slow enough & let the tires crawl instead of using wheel speed, and can keep the rocks off the suspension it's not too bad. Honestly, with how light these rigs are the wear is much less than on a Jeep or Toyota crawler.

For the type of riding you are planning to do - per your post - the 1000 would be a great car for you. But like you I bought a Pro XP due to the many updates and upgrades - ride command, more room, fold down rear seats, larger fuel tank, stronger chassis etc. That being said what your dealer told you about the Pro XP - needing to be run over 40 mph to not break is complete fabrication!

I have 790 miles on mine with 47 hours +/- - so that is a an average of 16 mph - I have not had a single issue - lots of time in the Dunes at speed and time in the mountains and desert at slower pace. I am running 32's on stock clutch and am on my original belt - it still looks like new! If you use the proper gear and don't lug the car you should have no issues.

Get the car that you like the best and go have fun!

Well.. See.. Those that jetted 2 stroked regularly and knew how to make peak power dealt with this all the time. Peak Power is lean, and so we'd often raise the needle or use different taper so part throttle was quite rich. We usually jetted the pilot as rich as it would stand too. This helped them get some oil and cool down a bit at every corner entry or anytime we were less then WOT. Being rich also helped throttle response too. But tuned like that they would often foul when ridden more gently. Mind you in racing or more ruthless performance games nobody cared. Everybody carried spare plugs and that was that.

There is many rules of thumb like this that make perfect sense. Like….

#1 If you own a Harley with speakers and don’t blast obnoxious music…even though you can’t hear it with short pipes. It won’t make it past 50 hour mark.

#2 If you drive a BMW, Mercedes, or a Porsche and use your blinker when changing lanes or merging. The vehicle will spontaneously combust.

etc..etc…

seriously though. That’s nonsense.

That is the first I have heard that one. I was told not to be afraid to use low range when going slow to save on belt wear and tear. So far no issues with going slow. I am more concerned blowing a belt running flat out in the dunes than I am crawling around in the hills with the family in low range. Belt temperatures shown on my Razorback are much lower crawling than hitting the dunes.
