my question is, Can a worn drive belt lessen the top speed of my Ranger?
I have a 2013 900 XP EPS , My top speed is 45 MPH. Is this average? I do NOT need it to do 60 MPH, But I have been told that it should be faster the 45.
If a drive belt would not do this, what other things might I check?
Thank You, for any help::

I had a worn drive belt on a Sportsman 500, and it slipped a lot so would imagine if it is worn to the extent that it can't grab, I believe yes it would slip thereby decreasing top speed. I would try changing it since it can't hurt to have a new one. Just make sure you break it in according to the manufacturers recommendations.
My two cents

Is it a crew or a 3 seater?

Yup.
Think about it. The primary and secondary can only squish together so close. Once the belt wears to a point the pulley can no longer "grab" it, it will slip. Five years is a decent lifespan for a belt. Simply driving along on the street will wear the belt as it jams into the pulley and then pops out to go to the next pulley where it jams in all over again. Pulley drives like these account for the largest percentage of power loss. I have heard for a 60 hp engine, the rear wheels only see around 40-45 hp. That is a big loss.
But, they are cheap and reliable, if treated well. And, they are easy to replace.

Well up until a few days ago my top end was over 50. Not anymore. Something has crapped out. I was complaining about funny noise coming from the rear end and now the thing is lagging badly. Hey what can you expect for 15 grand? A clutch and transmission that last a whole year? Unreasonable I guess. I am not a happy camper. RPM clamps at abuot 6500 or so but the top end in low is just over 20 and in high just slightly over 40. I am a total ignoramus when it comes to these clutch and transmission systems but if I had to guess it seems like something is hungup not able to finish the transfer ratio change. Plenty of power getting there but then blahhhhh.. It just pigs along.
I have heard these thing have a "fantastic" clutch and transmission system. I suppose I'll have to cart this thing 45 miles to the dealer but this is about the last polaris I am going to gamble on. Really for just a year and under 200 miles without being beat on or doing heavy lifting I am not impressed.

The clutch system is pretty simple. If you pm me I'll give you my cell and walk you through some things to check. I'd gladly try to help and save your trip to the dealer. All you need is a very basic socket set to check the clutches.

I also can't seem to get the rpm up over about 6500. It almost feels rev limited. I swear this motor used to rev up a bit more than this. Kick me down the steps if I'm dreaming but I thought I was seeing over 7500.... So much for that rodeo.

Yeah so 7800 in a heartbeat no load. (man i hate digital tachs) It would probably go more but dang it isn't exactly a puring motor. Loud and not pretty sounding. Egh. The racket this thing makes still makes me nervous. Anyway I'm thinking it might hit 79 or even more no load. But get it moving and it jumps up and then sort of "holds" back. Just like the way a limiter feels. Exactly like it feels with the seatbelt disconnected at about 15mph. Everything sounds fine and it feels like it is going to go but then BOGGG. Even down hill when I would expect the rpm to go up even if it is slipping or not changing gear ratios. It definitely feels like some sort of limiter. If it was my dodge I would say it was a speed sensor in the tranny but no check engine light or anything like that. I never look at the display. I noticed today scrolling around when I get to temp it says E 189. Ah. "E" is for engine? I never look at these displays. : ) Can ya tell?

Not sure which model you have. Stock RPM for 900 ranger is around 6800. Most rangers are ride by wire IE no throttle cable. The ECM reduces the throttle opening the faster you go so it does act like a speed limiter maybe 60 on a good day. There are companies that reflash the ECM if you need more speed but that will void any warranty. I do not recommend free revving any motor , it can cause serious damage. I believe the ECM also logs those events along time at wide open throttle.

Yeah but it had more top end than this a week ago. 25 mph absolute maximum in low gear. I am checking it in low because I have limited space to run it with the belt cover off etc. It hard chokes at 6400 rpm. I never paid much attention to it before but I don't remember the hard limit of under 25mph in low. In fact I rarely use high at all and low was always good enough. I'll have to bolt the covers back up and take it down to the road for a high gear test but I am going to bet it won't do over 40. I know it ran over 50 just a short time ago.
Anyway good to know the rpm is normally choked at 6500 or so. This one is 6400 to 6450. Not close to 6800 at all. That 400 revs wouldn't translate into much more than a 6% change in speed unless something else changed in between those 2 points. Really not even another 2 mph. That is unless something changes in the transfer ratio.

2016 xp900 eps - single bench seat. Lightly used and babied for the 200 hours I put on it since we drove it from the dealer showroom. 6400 seems low but the difference is not enough to matter much. 6450 I think I actually saw it hold at. It definitely HOLDS there. Not a bit more on the flat over grass. In low 6800 wouldn't even amount to 2mph difference.

okay - so this is crazy. I had picked up an after market belt when we first got the ranger because I heard horror stories about how crappy the whole belt system was. Recently I started having various problems ending with this loss of top end both in low and high gear.
I did what was recommended and pulled the belt cover. It was pretty clean looking in there. Better than I expected. Still I blew out the dust and pulled the belt. It looked absolutely fine to me. Sharp edges on all the teeth no frayed or burned or warn looking areas. The new belt was not a polaris brand. Gates I think is the brand. I noticed it was just ever so slightly wider than the original and quite stiff compared to the used one. So I put it in even though everything I could see on the original looked to me like it did not need replacementing..
Gheez that is a fun job. Wholly crap I am just getting too old and too wussy to be doing too many of those but I got it in. Ah. Hello. MUCH improved start ups. Less jerk etc. And oh that funny clatter / jangle noise I mentioned on a different thread. Can't hear that any more. And top end? Ah - I get nervous at 55 going down the road and that seemed to be pretty easy to hit. Odd that the 6400 rpm limit doesn't seem to be a factor in high gear. I saw 7000 at one point. What's up with that? More mysteries.
So what about the mph? Almost 30 in low gear on a flat over grass. WTH. I really would not have replaced that belt by looking at it. Cracks me up but that clatter sound in the rear end was significant I guess. Or at least an indicator of some wear. I'm not going to think for a minute blowing a tiny amount of dust out did anything so it is pretty much the belt.
Well I guess I'll keep a spare on hand but who would have thought as gentle as this machine gets treated that it would crap thru a belt in one year. Seems like there might be a better design someplace. Anyway I am happy to have the carts nads back and happy to not hear that jangley racket in the back but man I was sort of expecting to do better than a belt per year. Good thing we don't actually do any work with the machine. THanks to everyone offering suggestions.

7000 is not a problem same basic motor in RZR 900 which run higher RPM than that. Many things can cause belts to wear faster. Biggest enemy is getting to much heat in belt and clutches. Some of the known causes Warn or out of align clutches, high range at low speed, prolonged high speed runs, pulling heavy loads, getting stuck mud holes and if you have bigger tires it happens faster.

Belt life is a direct result of how the belt is treated. Mine is 4 years old and I did a two hour spray application yesterday with hundreds of starts and stops, mostly in low range to keep the crawl slow. Belt still hooks up and pulls nicely.
Belt stress under hard lock-up during high power starts (high heat and wear) or super slow operation where the belt is constantly slipping (more heat and wear) rather than being locked up is the leading cause of wear.

I hate to sound like an unhappy customer but I am.
I get it that beating on the belt causes issues but for some dumb reason I thought I was buying a utility vehicle not a toy. We don't run or race or excessively stress the machine. I do a few minor tasks that I used to do with my dinky honda 450es. The honda is something I actually considered a toy from day one. As for the ranger - For my money this belt/clutch system could, and should have been a bit more robust. When I am done paying for this ranger I'll unload it and see what else is out there. In between then and now I'll get a box of belts and replace them often.

Understand your frustration, couple of options that might help. You can add a fan to the intake duct of the belt cover. ALBA Racing has a belt temp gauge that can be paired with a fan, gauge can be programed to turn fan on so it only runs when needed.

stop and go is the biggest issue with belts as far as I am concerned. After several years of using a utility snowmobile to access our cabin, I changed the belt out pretty regular to keep performance up. I changed the belt on my 2017 900xp this spring after running tracks on in the winter. Pretty inexpensive way to get performance back. I replaced with a gates g-force belt I got on amazon. works great.
