We had a demo Dynamix for a ride this past season and it was mainly for my wife to ride to gage for her next sled. She rode my old XCR (2024). After some time to dial it in a little for the short time we had it she liked it. She was even adjusted the suspension towards the end of the trip and could tell she was riding at a faster pace than normal.

My sled is a 2025 136 XCR with progressive front springs, dual rate FTS and revavled RTS that I like the way it rides and handles. Rode the dynamix and liked the ability to adjust on the fly and flat corners for being all stock. Being my sled is not stock for suspension still thought my sled rode and handled better to my riding style. The 3 different setting on the dynamix were a noticeable difference between the 3 but I was looking for a ride/handling in-between the 3 ride settings. This was without adjusting the suspension at all just me and my wife swapping out sleds on the trail.

We have a Dynamix ordered for her this coming season and I do have a set of Progressive springs for the front coming from Andy at Wenzlaff performance for it. Really liked what they did on my XCR for ride and handling. This year will be a little more experimenting with her sled to see what my next sled will be. From what I experienced riding a Dynamix last year for me is still doing some work on dialing in the sled with spring changes and possible shock changes or not. But then having the added benefit of changing the sled on the fly to the different trail conditions

 

I really like my Dynamix. About 2,000miles last season.

I have ridden my Dynamix on some pretty beat up junk trails with a large group of about 15 guys and everyone was complaining how bad the trails were and how beat up the riders were. Yet I was thinking yes they are rough but not that bad.

I am a big guy at 6’2” and 300lbs. I added the HD rear torsion springs and that’s it. Great ride on smooth trails or rough. And you can really feel the difference in modes When you change.

In our regular group of 4 or 5 if someone has gotten beat up pretty bad on a sled that day we will switch out and share a little of the pain. It used to be we would switch to the Skidoo with smartshocks. Not now. They get the Dynamix for a break and recovery.

This is good to know it works for you being a bigger guy. That was a concern of mine as I run about 260 with gear. I typically run XCR's for this reason but have thought about giving the Dynamix a shot this season.

 

If you like to ride aggressively you can get the bigger springs as @Doug S pointed out. But having ridden a Dynamix with and without those bigger springs and a very well setup XCR back to back on similar/same trails for 25-30 miles at a time, IMO the Dynamix is the real deal.

 

We picked up a VR1 Dynmaix at the end of last season for my wife. It is also our first Polaris. I was expecting to be more blown away by it. Everyone raved about how flat it handles, yet ours has no problem lifting a ski in the corners. The front also feels mismatched to the rear. Like it is stiffer in the front.

To be fair to the sled, we only rode it two days before the snow melted, so I need to fiddle with preloads a bit more. It was setup soft for my wife.

Coming from BRP products, the rest of the sled was stellar. Ergos, power, 7s, and smart warmers are great. The 2025 tune is a real ripper.

 

Just an FYI the FSS for a Dynamix is a 2" or close to that same as an XCR. If you have dual rate springs on the FSS they will fit a Dynamix. Pull them off your XCR and put the stock springs back on.

 

The way a Dynamix sled plants the outside ski with zero body roll when rolling thru a corner is game changing maybe power steering will be next ? !

 

This is a good video on making changes to the Dynamix suspension. This describes how changes effect the Dynamix operation. The springs they're talking about are available in the Munson link below. These are the same springs @Doug S is running on his XCR.

Something else to remember, and keep in mind, this is a gross oversimplification....Dynamix shocks are still just shocks. All the internals are the same as other Fox shocks. Dynamix just has infinite and continuously adjusted clickers that are changed in real time.

Yes you can still revalve the Dynamix shocks to dial them in closer to your riding style and still have the adjustable on the fly of the Dynamix system.

 

Rebuilds are the same as any other. The valve is open when not powered so bleeding is not an issue.

 

I would suggest anyone buying a Dynamix ride it first for a bit before making assumptions on required changes.

i had almost convinced myself I needed to opt out of VR1 Dynamix because of my size. Dealer said ride it and let’s see.

Then I picked it up and rode for a few days. Back to dealer for HD rear Torsion springs. I did not touch anything else. No ski or front track shock spring adjustments. Except I added Gripper skis from day 1 because I wanted them. Maybe the dealer did an amazing setup.

But it handled pretty much any trail conditions we hit. And there were some pretty brutal trail conditions last year due to volume of snow and groomer breakdowns.

One guy in my core group of 5 has ordered one for this year. Second is thinking hard.

And I had zero issues with the sled in 2,000 miles.

My buddy with 850 skidoo with Smart shocks had wires ripped out 3 times on rear skid.

 

Actually the smart shocks are a lot more advanced on paper. The smart shocks are smarter. Ski doo markets smart shocks for performance riders though where Dynamix is marketed to trail luxury riders. I think ski doo missed the mark big time on the programming on the smart shocks aftermarket like accelerated technologies has a reprogram for them that is supposed to make them work like they should. On the other hand Polaris really nailed the dynamix shock calibration everyone that rides them is amazed how good they work. Even though on paper the smart shocks should blow them away.

 

i have 5 customers with DYNAMIX sleds. all love them and have not revalved or changed springs etc. weight of the 5 guys is 185-300lbs. all stock except our clutching and trs valves and some with speedwerx tunes.

 

Looking forward to riding one this season and slamming it through tug hill weekend trails

 

I have a 2026 ordered. At what rider weight should someone consider different springs?
I bought it because of the reviews and the fact they are Fox shocks. Coming from many years on a Cat, I have grown to love Fox shocks.
I'm no expert, but the springs (for the most part) simply suspend the sled at the correct static height. The shocks really control compression and rebound as you ride.
I'm still a fairly aggressive rider... But I can say my experience with my 2022 ZR RR (Fox QS3R shocks) showed me that even aggressive riders can get beat up with harsh shock valving. But they will save you when hitting a crater at 75 mph (UP Trail 8 RR grade in the afternoon)

Won't change any springs until you ride it. Everybody is looking for a different feel in a sled. The way the Dynamix comes may be what your looking for.

 

The bigger progressive springs were noticeable IMO when riding it a week apart after install. Maybe my brain was being tricked, but I remember telling my bud who owns it the time I rode it without the bigger springs, I thought that’s all it would need to be perfect for how we ride. And I was confirmed in my thought after he put them on and I rode it.

But I agree with @Doug S dont change them until you ride it stock. May be just what you are looking for in the ride.

 

Dynamix sleds come with a stiffer spring then a VR1

 

In my opinion (and most motocross guys), if you don't bottom out every now and then, you're not using all of your suspension.

 

That's more than an opinion, that's basically restating a definition.

Full travel is measured from maximum unloaded extension to maximum compression.

 

I like mine to just kiss bottom in the worst case senerio hit to the suspension. I’ve rode a lot of sheds set up “plush “ that are downright dangerous on the unexpected big hit. The chassis defection could throw people right off or the whole sled can change course. So I 100 percent agree they should be able to use full travel but I think some confuse able to use and normal to use with no reserve. No reserve in travel in how guys get thrown and hurt on something they didn’t plan for or when pushing the sled past what they normally would. To stiff is another danger. Anyway I believe guys over 200 that ride rougher stuff will need a revalve. Everybody I know who pushes a sled that said it didn’t need anything were sub 200. With that being said I also agree ride it first one may find they don’t need a revamp just a tweak to the fts.

 

Yes, heavier springs will require the rebound to be slowed. The dynamic system sounds impressive, but for some, springs and valving will still be needed. There is limits of the on the fly adjustments that it can fix.

 

What does polaris say about the use of stiffer springs on the dyna-mixer for heavier riders?

 

At this time, Polaris directs you to use Rear Torsion spring adustment or replacement to adjust the balance of the sled (Balance between weight transfer and ski pressure). Light or heavy riders should consider installing optional torsion spring pairs.

They do NOT have specific spring guidance for Dynamix suspensions. The owners manual, has some significant faults at this time.

 

So many dont understand how important this is… 👍

 

I’d like to try lighter torsions on my wife’s, but I don’t want to be the first one to try it lol

 

You can also split the torsion springs. Run one side with the stock spring and one with the light. Gives a middle setting between stock and light

 

We have over 1500 miles on our Dynamix. Overall, a very impressive sled. It works.
Positives: 1. Better riding. 2. Flatter cornering. Less rider input needed to go fast. The 3 modes change the starting stiffness of the shocks. We use the middle mode(Rally) the most. 4. Extreme mode is great on smooth/fast trails, but too stiff for moguls. 5. You will notice that sled is significantly different than a normally equipped model once you ride one. Ride them back to back and you'll agree.

Negatives: 1. Could use more compression/rebound dampening for more aggressive riders in Rally mode. But not much more is needed. 2. Expensive. 3. Shock rebuilding is more expensive. 4. The switch to change modes should be handlebar mounted, it's difficult to reach when riding.

Overall, we are happy with the sled and will keep it for another season. I'll most likely send the shocks to Bruce and Jessie at Southside in Mass this fall for a rebuild and upgrades. We do have Tanner's progressive front springs to try later in the season. Bruce and Jessie seem to think that this improves the ride and handling.

Yes it does!

 

I can't think of a bad thing to say about Dynamix. Polaris has been testing that system on the RZR for quite a few years, and I haven't heard any wide-spread problems with it. My wife and I both demoed two VR1 650's last season, one "regular" and one Dynamix. Both of us preferred Dynamix by a wide margin. It erases inside ski lift and makes cornering much easier. I thought it was interesting that when Levi Levallee rode 500 miles along Superior's North Shore in one day last winter, he took a Dynamix instead of an XCR.

 

Couldn't you have dialed out the ski lift with a couple of clicks on the IFS shock.

 

just put heavier weight oil in them. this has fixed a number of walker evans shocks without a revalve. it works. not many ride as hard as my son. he raced sno-x . the rougher it is the better he likes it. i made his 22 XCR into weapon by putting the cross country valve and spring on the front track shock with 7.5 wt. oil and just 10wt. in the rear. 7.5 in the IFS shocks. night and day better. and he has ridden sleds with exit shocks etc.

 

Because I can’t leave stuff alone I tried 500 miles on long tails on my Dynamix last season mixed with a few different fts springs, it’s going to take some homework on revalving even maybe a different program for them to enjoy any benefits. I do have 2 seasons on them with my CC shock packaged XCR and while it’s dialed in and works amazingly across a wider range of conditions with a single set up compared to before the long tails the Dynamix is just as good maybe a tad better straight out of the crate. I cannot express enough how good the Dynamix sled works, I see absolutely no need to invest in time and money tweaking shocks to run the long tails on it I don’t think the reward will be as great as it was for the traditional suspension, going to a non bypass rear track shock body for a touch better valve stack control could be a wiser investment and maybe only something the hardest or pickiest of riders would ever need. (Ones built and ready to try) I did end the season bumped up to HD torsions for more aggressive ski bite under hard acceleration mid to corner exit along with C&A XPT Skis. I had all the shocks rebuilt this summer I believe it was 10 more per shock than a traditional shock and I purchased an updated Fts cap with std. service port vs the micro unit it came with these are available directly from Fox through Andy Wenzlaff black caps the new, orange stock the other 3 shocks use the std Fox needle.

 

Did you make any changes to the valving or rebound with the different springs?

 

@ed#215 that sounds great! In the past I've had Ian at Monster Performance revalve my Fox shocks when refreshing. My QS3's on a 2017, got the center shock stiffened, and my QS3R's on a 2022 RR softened.
I'm hoping I only have to get these rebuilt now and then.
