They finally came out with a 1000cc 4-stroke twin out of their side x side. I can’t find any HP numbers on in yet.

They are saying 90-100 hp

Did you find that on the website or is it random forum talk? I was looking at their side by sides and HP is 90-100 in RZR’s and as low as 61 in the Ranger. I had a 900 RZR S and with 75 HP it did really well and felt impressive. But sleds seem to lose a lot of power between the engine and track. For a work/recreational sled it’ll have plenty of power but likely won’t feel too sporty in a trail model. I’d be curious to see how it rides and handles? My Vector had good power but the chassis sucked.They are saying 90-100 hp

South side sales and Jesse James had it in their web review. South side owner was out at the test ride few weeks back and got all the run downs on all of them.

Looking at the prices of the Polaris sleds is crazy. A sled with less than 100hp is over $15,000.
They had me interested in another sled until I saw the price with painted tunnel and rails, tall windshield, 4 stroke then it was over $16,000.

yea xcr was at 19 and change and turbo vr1 I was at almost 23. Skidoo isn’t far behind when you get done with their cinematic display rooms for command centers they use

Its been mentioned as 'about 100HP' by some of the ambassadors and you can tell by the way that they talk about it that in its current implementation it is not aimed at the performance market.
Snowtrax mention
In the RZR the 900cc twin 4stroke turbo makes 181 HP so that is probably somewhere in the production pipeline but its probably already a tight fit under that slim bodywork without the turbo.

Earthling, thanks for the link to the video!
I suspect it would compare quite favorably to my old ‘05 Vector power wise. Traditionally Polaris sleds have always been down on power but made up for it with more efficient clutching. As I recall my old Vector was 120 hp? That sled was likely heavier than this new Polaris and I’m sure it was a ton heavier out on the snow with all that ridiculous ice build up in the tunnel. I‘m speculating that this new Polaris would be very similar power wise to the Vector in a chassis that is light years better. I find it fascinating that Polaris can fit this motor in the Matryx with the forward facing exhaust. I remember Yamaha claiming the 4-stroke exhaust made too much heat and had to be cooled by snow. Looks like that was complete BS. I don’t like the price of this new Polaris and I’d want to see how easy it is to change the oil but I bet it would be enjoyable to ride. The more I think about it the more interested I am in it.

Non starter for me at 90-100hp. Also figured when they claimed "purpose built" it was code for "purposely repurposed" from some other application.

You would think at these prices OEM's would price themselves out of business, but it seems they can't keep up with sales even with these high prices OEM's are asking, not sure when it will ever level out, sure makes it hard for the average Joe to buy a new sled, it would be a long time before I would pay 23 plus grand for a sled with the winters we are having for the last few years, I have not put one mile on my Apex this year with the lack of snow, hard to travel or take 2-3 days to go sledding where there is snow where I have been busy at work, hopefully I will put a few miles on before its over, worst season ever.

If Yamaha engineers claim that it would create problems in their design, I would trust them. Yamaha has some of the best engine engineering talent in the world, but they tend to overbuild a bit. They after all took the 4S route when everyone else had abandoned it. But the main reason I trust them is experience across all of their engine efforts where yamaha has proven to be bullet proof. That does not however mean that Polaris didn't find a different approach and it remains to be seen how robust and reliable those engines really are in the long run. I know that my apex is a rock solid beast. My buddies that ride BRP and Polaris are already asking if I am keeping it (bought a winder) because they want a backup plan for if/when their sleds need a rebuild. I agree that the Polaris looks interesting simply because of the weight savings, it could be the perfect sled for my wife. I still want to see a small displacement, turbo 4s, hopefully from Yamaha (in whatever chassis).

The Doo 4-strokes have forward facing exhaust and don't have issues that I'm aware of. I could be misinformed though. The ones I've rode with (900 Ace NA) have been super reliable for the owners.
I also eliminated the snow cooling hole on the tunnel of both my Phazers a couple thousand miles ago. Zero issues and WAY less ice, win win!

Sounds like from comments its the RZR motor with a dry sump.Non starter for me at 90-100hp. Also figured when they claimed "purpose built" it was code for "purposely repurposed" from some other application.
