16 axys pro rmk 155 2.6 Clutch Belt

My machine is not at my house here so can you help me.

What cvt belt does the new axys pro rmk take? I assumed it was the same as the 15 axys short tracks that had a longer center to center distance, but then a friend just told me he thought it was the same as my previous 2011-2015 pro rmk's

So... which is it?

I Talked to Carls Cycle today,
The angle on the sheaves is the same angle cut they have been doing for years and I have run on my Pro sleds for years.

Here is a post from Carls Cycle: FWIW..

The new belt is a better more durable compound, and will fit on the older model pro's. The new part number by the way will be 3211183 if anyone is interested. The 2016 also has a new Primary that has sheaves that are cut to match the belt angle better (exactly like the clutch mod that we developed here at Carl's), as well as helping to reduce belt heat. The belt will retail for 199.99 to the best of my knowledge, though prices may change as usual.

The point is that the belt is not dimensionally different. The sheave angles are different as in what Carl's has been doing with their clutch mods. Another trickle up use of technology developed by smart mechanics like Jack and his guys at Carl's. Their clutch kits work very well. Unfortunately, he will not have one out for the 16s until he gets time to ride it to see what, if anything, can be improved. I presume that a helix, springs and weights may be what they recommend.

I picked my sled up there today. I will be installing the Diamond S Quiet muffler, the Ski Doo scratchers and removing all of the government mandated stupidity labels tonight. It sure sounds different mechanically than the Pro. Not sure how much of that is the suitcase muffler. I will find out tonight when I put the Diamond S on it.

I forgot to add that it doesn't vibrate/shake around nearly as much when idling compared to the Pros. Motor seems a lot smoother mechanically.

I agree, and wow, is it quiet or what!

This is what I was saying yes its a more durable compound but they are not sure on the performance level side of things. My pro's with Carls cycle clutching and sheaves cut were never hard on belts before.

The cut that Carls cycle had on there sheaves were the angle to the proper belt for the pros 11-15. Stock the pros came with a multi angles primary sheaves. (one angle lower in the sheaves and one higher in the sheaves)
My assumptions are but I did not ask exactly but if they were cutting the sheaves to the previous belt angle properly then this belt angle should not have changed but the primary sheaves changed.

I can tell you on the 2015-16 short track Rush sleds the belt is harder, more durable, doesnt blow up but it will loose alot performance as it wears in compared to the previous shorty rush sleds of 2011-14.

This has been the trend on the RZR's also. They come out with a new belt compound every year it seems, now they have gotten so they wont blow up but they loose alot of rpm as they wear. For performance wise Carls will tell you the best belt to use is the 2014 belt for the rzr 1000's

I don't quite follow. The 2015 and previous belts lost performance as they wore, noticeably after a point. Even as performance dropped off, the belt was still a long ways from blowing up. I've never blown a belt on a pro...because the Performance of an old belt sucks and you want to change it anyways.

So the new belt may make it longer before dropping off in performance theoretically it sounds? Good thing. What is the concern - that the performance will be less throughout its life? (Until performance drops noticeably - ie end of life). You were never supposed to run any belt till it blew...
