Is anyone going to build an adjustable tensioner for the quick drive so that we could use the 19 and 44 gears off of the 13 to 15 pro's? That would give us additional options of 2.32 21/43 and 2.38 21/44, and if a one cog larger belt was available than a 2.27 ratio 22/44 would be available! This would be a lot less expensive option and you could get belts from your local polaris dealer! That 2.32 gear ratio sure would be nice 21/43!

I doubt that you are going to find longer belts in the 11mm pitch that are worth a darn... but who knows?
2013-15's had 21/44 gearig, the axys 22/43
The reverse question would be interesting on a ProRide PRO-QuickDrive™... is there enough length in the new longer drive belt to allow a tensioner to be used that would give more "wrap" to the belt on the top sprocket for more tooth engagement and less slippage... maybe an aftermarket 11mm spaced, 20 tooth, top gear and a tensioner to give a more economical system that would yield a 2.2:1 ratio (or 2.4:1 with 7 tooth, 3"-pitch drivers...or 2.5:1 with 7t-3p drivers)... Hmm.
Stock AXYS belt on ProRide Quick drive, tensioner, 20 tooth custom top, stock 44 tooth bottom... Would that work and have enough dogleg in the belt to get the improved tooth wrap?

Do you think that it would slip with a 21/43 or 21/44 with a belt adjuster, obviously my 14 was 21/44 and it never slipped and has no belt adjuster! I see that fire and ice has a nice looking belt adjuster for reasonal money! Also since it has a 7 tooth driver it wouldn't load the belt as hard. I do most of my riding around 10,000 ft. so lower gearing sure would help.
One issue I have spoke to Tom @ TKI is that in cases the stock QD drive belt in stock form can balloon out-and he has a belt adjuster that fits the stock configuration.- really it hold the belt from leaving the top gear
Updating to his gears and the TKI belt with the dog leg-with more area coverage in the top gear the same belt adjuster works .
Working on a "correct" gear ratio and dropping in the 8 tooth drivers to get the correct rolling resistance and getting the Axys where it should have been. 7 tooth drivers is not going to cut it no matter how much you change gearing. Approach angle is way steep!
For us that ride 9,000 and up, a clutching change should be considered to 62's ( Min) from the stock 64's that are good to only 8,000'

FYI, the Belt Deflector from Fire n Ice IS NOT a tensioner!! It's purpose is to keep the belt from ballooning out and climbing out of the sprocket teeth.
You will have to keep us posted and let us know how much it does change the approach angle, that will drop that approach angle down just about half an inch which will be a nice improvement! Just going to suck to loose that tunnel clearance and expose the drivers to foreign objects, but does it really matter that much?
As far as clutching goes, I'll probably be going back and forth from 60's to 62's depending on altitude, temp and gearing. I'll probably just end up going with the tki belt drive so that I have more options for the future
Its going to be fun to play with this axys!I'm also considering going to a three inch track with 7 tooth three pitch drivers and trimming the outer lugs to 2.8 to make the track a little more versatile and give more clearance at the front of the cooler and bulkhead! So many options!
Look at 13-15 Pro's and see how much of the driver is exposed vs the 7's on the Axys- splitting hairs IMHO...
I like where your heads at, also might make it so you can change/install a belt without removing the pullys

I was referring to if you put a 8 tooth 2.86 pitch driver in place of a 7 tooth on the axys chassis.
Literally every belt drive manufacturer in their design guides say to not backbend their belts. This includes the belts that TKI uses and proceeds to backbend anyway. It also really includes the quickdrive belt which will break if you backbend it's carbon cords
Not to mention it's not any cheaper. Kurts gear down is $595, Polaris would be $525. And then stock belts are $215, where kurts are $120

What's the c-c from axys quickdrive versus proride quickdrive, has anyone measured this?

Just to clarify, the belts we use that we back tension are made to be back tensioned. That is why I designed it that way, with advice from Gates Corporation. If there is any doubt I can give direct contact info to the gates engineers who showed and told me how its done. This is why we also use only gates belts. If any one has questions feel free to contact me with questions.

This is nice to know and now i will be buying your belt drive system! Thanks for the update!

Any updates to this?
Is is possible to use 2016 belt with 2015 gearing? Does Kurt's polaris have a gear down kit for axys pro available yet?
Damn, I need snow!

I don't know if the words "a lot less expensive" and "local Polaris dealer" should ever be in the same sentence.

Yes Kurts has new gear downs and "gear the same" kits ready to go. Saw them at the Salt Lake Show, look like a solid product
Is that conveyed only by word of mouth or is it written in any of their design guides for their belts. I haven't seen it, but it would sure be useful information
