HO,
Just so you know. The guy that has the 850 that we ride with who broke his belt in extremely easy (maybe to easy?) He also seems to keep his bike in low range in the same spots that we do (which is most of the time).
As for going over logs and rocks and stuff... he seems to go over them without so much as spinning a wheel, and without having to apply to apply hardly any throttle. His bike crawls over them effortlessly (probably because he's in low range). As a matter of fact, he seems to transverse everything easier than most of the other bikes.
Anyhow, we have a flat mile or so stretch of smooth logging rode that we always like to "open them up" a few times. He was going WOT a few times from about 20 - 25 MPH. We were all doing it. The third or fourth time he did it, I saw him back off the throttle and look down. We could smell the belt.
Sure enough, he took it back to the dealer, and the belt is shot... at 37 hours and around 210 miles.
I called him and told him about some of the advice and comparisons to snowmobiles and such. He really didn't want to hear it, and I can't repeat what he said. LOL Can't say as I blame him... he is really ****ed.
He said he's trading it in on a new KQ or Grizz as soon as he gets it back. He rode his old KQ over the same turf, in the same manner for 5 years... never a problem.
I have no idea what is wrong, but it really makes me mad... I wanted to ride it a couple more times.

Very interesting....thanks for the info..I've heard about a few failures but no one is reallly explaining how the machine is being used or if they smell the belt during any particular type of riding. Weird the "testers" didn't experience this. It sounds like his is exhibiting basically the same characteristics mine has...I assume the WOT passes were in high range..not alot of fun to do WOT passes in low..since it hits the 40 mph brick wall and the motor is on the rev limiter as soon as you nail it.
So it is likely slipping under WOT in high range on relatively flat unobstructed terrain at speed..hmm sounds real familiar. I guess 2 machines experiencing relatively the same thing doesn't mean anything though..
I'm betting the times he "played " like that did the belt damage..not the trail riding..
I do think it is sad he is trading it because of that but hey that is his choice and I can understand the frustration...I really think that the belt would last a long time if you didn't go WOT in high..but I also understand what is the point of having the power and calling it "extreme performance"? I'm an optimist I think Polaris will see that the clutching needs work and fix it. Who knows a simple clutch tweak may fix the issue. I'm not going to spend my money and time to find out though as that can be a expensive trial and error road to hoe.

Yep, it was in high range. We all shift into high for that stretch of terrain... that's the fun part of that section. Besides, it's one of the only areas that we can ride in high range.
I agree, it seems that one could make the belt last the 5000 miles that Polaris claims if it is "babied". However, I doubt that he want's to be the only one that can't do it... and again, I don't blame him.
Maybe the dealer will look at it closer and find something else. Maybe the belt wasn't adjusted exactly to the top of the sleeve? Who knows?
What really ticks me off, is that he was the one that was going to buy my 500 for his son... now he wants no part of Polaris period.
EDIT: BTW... that's why I was particularly interested in this thread.

If I handed you a ATV belt from a 70 hp ATV and one from a 170hp sled you would not be able to tell them apart,they are the same technology and strengh.
If your not getting 2000 miles from a ATV belt then the alignment or deflection is not set up right. Not because 70hp is alot of power for a belt CVT system,far from it.
A 70 hp snowmobile is a introductory sled you would buy your girlfriend or kids.LOL
If Polaris put 70hp 850 motors in there sleds they would be the laughing stock of the business.

If you handed me a belt from a sled and a belt from an ATV, I would say "Wow this sled has a much wider and thicker surface and is much larger, than the belt on the ATV". Sleds rarely have the traction or lack of slip that an ATV has.
I've shredded many a belt on both sleds and ATVs. Something is wrong with the clutch. WOT is a point of stress but a well built clutch shouldn't ruin a belt that fast. If this new XP of mine gives me any grief, I'll load it up and drive it back to Polaris and personally meet with the CEO for full refund. It's too much money to pay for crap.
DavidXP I suggest you take it back right now and tell that dealer to change the clutch under warranty and full refund of belt change. No excuses, even with poor use of a new machine, for a belt to go that quick. I'd call BS on Polaris and your got to pay to play dealer.

Hey no big deal, you just said "you would not be able to tell them apart" maybe the same material,, but size is different.
My only point is I have never lost a belt due to a poor belt,, it was always a clutch problem,, alignment, wear, rust, corrosion, springs, rollers, or something else.
Novice riding shouldn't ruin a belt that fast. HI, Lo, WOT,,,,BS. Bad clutch!!! Design or factory lemon hard to say till more people ride the new XP for a while. If that 850XP is that touchy it is a crappy design.

A 70HP ATV may not need as much contact area as a 170 HP sled...but it may need a little more than the 850 XP belt has..that or higher clutch clamping force. The 850 set up, in my experience, is not grossly inadequate but it does need some work..especially if you intend to run a tire that will get some bite...even if it is a 26" tire...or like to play with WOT in high range.

I suspected the sled belts had more contact surface...thanks for confirming that.

The XP belts are not as easy to get to since they are no longer on the left side. They are sideways under the seat behind the engine. I haven't changed one yet so I don't know the process. But they look like they are a bit tougher than the tradional.

Yea. I may have over reacted in my first posts here,, but I just traded off a 700 Sportsman to get this XP. I lost 3 belts on it in less than 600 miles,, the last time they may have got the clutch fixed right,, but I was sick & tired of being towed in with my buddies 450 KingQuad,,, who hasn't changed a belt for 6000 miles,,, and has towed me 60-70 miles of that. I bought the 700 used and suspect the previous owner did something to it,, he chose not to share with me. That is way different than DAVIDXP getting the shaft at his dealer(in my opinion). By the way I got charged 30 min @ $80 per hr = $40. I have changed it myself also but wanted the clutch looked at while in there.
I just am not in the mood for weak equipment, this year. If all goes well I'll post it all over the internet.
