Polaris Matryx Engine & Chassis Differences

MY21-19 650 & 850 ENGINE SPECS

This table shows changes and similarities for the Matryx 650/850 engine parts and the MY21, MY20, MY19 850 Patriot Axys flatland engines. It is not yet complete, some of the parts books are in conflict.

Differences for a component are shown by the symbol: <<
OR by the symbol * when there are more than 2 columns.

MATRYX Suspension and other Parts Specs

This table shows changes and similarities for the non-engine non-powertrain parts for the MATRYX INDY VR1, Launch Edition, & SBA 146 sleds. The shocks & coil spring table is by itself, because the ONLY difference between INDY VR1 trim, and INDY Launch Edition trim IS the shocks & coil over springs. And the 7SDD display.

MATRYX Engine & Chassis parts specs & differences

Linked from FAQ as of May 2, 2022 Polaris Matryx Engine & Chassis Differences MY21-19 650 & 850 ENGINE SPECS This table shows changes and similarities for the Matryx 650/850 engine parts and the MY21, MY20, MY19 850 Patriot Axys flatland engines. It is not yet complete, some of the parts...

www.hardcoresledder.com

Changes made to post#1 above.

Fixed a couple typos,
Completed finding & documenting, the significant changes to the 850 Patriot engine back to MY19,
Added listings for the .438 Swaybar & bushings to the Suspension table for folks that need to SIDEHILL,
these are the same parts that some took off the AXYS ProX sleds to make them corner better.

Sideshow Bob · Sep 25, 2020

Thanks for making all these specs available I was just looking at the front track shock says Walker Evans is that not supposed to be a velocity also?

ExcursionPSD · Sep 25, 2020

Velocity shocks have a Piggyback reservoir that mounts in the middle of the shock, not at one end of the shock. This allows them to have their shocking action change and get much stiffer, when the piston goes past this middle travel mounting point as the shock is compressing. Pull up the online parts, and you will see that the Matryx FTS shock is short, and HAS to mount the Piggyback reservoir at the upper end of the 2" shock body, so that there is room for the spring that goes over the shock. For this reason, it is NOT strictly speaking, a Velocity shock, and the Polaris parts book calls it exactly what I have in the table.

The Clicker knob for adjusting compression dampening is key 14.

Sideshow Bob · Sep 25, 2020

Okay great thanks for the clarification

Added the Crankcase. Same part# for ALL 650/850 Patriot MY19-MY21
Added the Braking System. Only changes are the New Stealth Master Cylinder, only on Matryx
Added the Drivetrain bearing, flangettes and seals
Added the Rear Suspension rails, hifax, (different for 129,137,146)
Added the bogie, rear idler and carrier wheels & bearings part#s
Probably added some typos, we'll see.

MATRYX Engine & Chassis parts specs & differences post#1

Changes made to post#1 above:

Corrected part number for .431 optional softer sway bar. This is used on XCR & Pro-X sleds for better sidehilling and more compliance if only 1 ski hits a big bump or hole. The sled will lean more on flat turns.
Updated some shock specs, still incomplete information in the parts book.

Added standard 0.531" ID SwayBar bushing specs
Added specs for IFS,FTS,RTS shocks including IFP depth & gas psi

Sledtuner360 · Dec 3, 2020

Odd that ifs shock extended length is same and compressed length is same but assault shock rod is longer in length. Just a misprint maybe?

akvanden · Dec 3, 2020

Just like the old days on PolarisFiles (RIP) - tons of great info from ExcursionPSD!

ExcursionPSD · Dec 3, 2020

Yes, you are welcome old friend! I just make up whatever isn't easy to find.

Doug S · Dec 3, 2020

Its interesting they're starting to vary the nitrogen pressures now where it was 200 psi across the board. Ski-Doo is also starting to vary nitrogen pressure in their shocks.

lennstang · Dec 3, 2020

Thanks ExcursionPSD. Great info! I think we should rename you...ExcursionOCD.

1fast444 · Dec 4, 2020

ExcursionPSD, can you list all the free lengths and wire diameters of all the IFS springs used in your encyclopedia! Thanks!

You can see that there are basically 2 types of crankshaft, the Lightweight for 650 and 9R and the standard for the 850's They all have the same stroke and are physically interchangeable. All use the same basic crankcase, but the 9R has some CNC porting to help improve air flow.

Each engine uses a different cylinder head. At this time information about MY25 engines is incomplete, there could be changes for the low elevation 9R and possibly Boost.
