20’ vs 22’ Polaris Clutch theory ?

Anyone have any thoughts on why Polaris changed up the clutching so much on the 2020 850 vs the 2022?


From manuals for sea level

2020:
74 weights
120/320 primary spring
155/222 secondary spring
Straight 42 helix

2022:
72 weights
150/290 primary spring
140/200 secondary spring
60/44 .36 progressive helix

I have neither of these as I run a TRS setup but trying to help a couple friends figure out why the 2022 feels like a pooch compared to the 2020. Telling me the 2022 does not pull anywhere close as hard as the 2020

Both sleds aligned, primaries shimmed, per TRS method

QD2 a factor I’m sure but 2020 does have pro gears so kinda close’ish in that regard

Any thoughts?

Not saying this is the case but historically Polaris has been known to "detune" after the first year or two of a new motor. Reduce warranty claims and make the next new motor look like a huge must have

I’m mostly curious about the change in philosophy.


Assuming the motors are somewhat close in power why did they go from 74 gram weights and a 42 straight helix to 72 gram weights and a 60/44. Different springs of course.

This is more of a clutch curiosity question than anything. What were they hoping to accomplish? In theory it’d be a different feel between those setups and likely what my friends are noticing . I’m hoping to ride them both this weekend

I ride 3000’ to 6000’, and have factory low elevation clutching on my Matryx 850. Been thinking about this as well, why Polaris uses such different helix for sea level.

I’m far from experienced in this realm, but I’m wondering if they went with the 60-44 .36 helix is to get it to upshift sooner in the RPM range. Maybe they figure low elevation riders are more inclined towards meadow bashing and relaxed riding where having a smoother more gradual pull through the entire RPM range is desired, as opposed to a more on/off and quicker reving, quicker back shifting feel of the straight helix for mountain riding. Pure speculation on my part, interested to hear others thoughts.

For me, I’m not content with the low elevation clutching, and am working on getting a quicker rev and back shift. Never thought that she doesn’t pull hard though!
