Anyone spent decent time on a Doo 850 and have a power comparison?
ya the 18 cat ctec is about 1-3 sled ahead or more every time and have lined them up a bunch on fresh flat or on a fresh hill climb.
the 850 is .005% larger to an 800, more to make the guys with the larger displacement feel better about the fact they spent money on a sled only to break even or are only 1/2 a sled faster. the cc thing is only subject to power delivery and cat does it better with more reliably on the motor.
poo on the other hand and reliability on a 800cc + motor with their track record make sure you get a 4 year and a 10K back up to make it past the very short season of winter.
if your mtcat1 your not going to like this post as Polaris is the laughing stock of motor reliability even without a new larger cc motor.

New motor ok cool
36” front end nice
Cool new running boards
Price wtf why so much
Alpha cat less by 1000 or more
Doo well less but shocks aren’t even in the ball park like why has doo not scraped the old school torsion springs.

Now what to snow check
My 2018 blue x 165” 3” shot has 1420km and motor is done I’ve been sleedless for 35 days and counting. Also there installing a new wiring harness and ecm

1. 850cc is 6.2% increase in displacement from a 800cc engine.
2. Your post is extremely difficult to follow due to your lack of proper grammar.
3. Polaris has clearly addressed many of the issues that plagued earlier motors (although I have had several units with zero issues.)

So, first off, even if I had cash in pocket burning a hole, I wouldn't buy this sled this year. By nature I tend to shy away from a v1.0 product, regardless of who it's from. And in this case, lets be honest, we're not looking at the best track record. My biggest reservation is that in recent history Polaris has been willing to accept a pretty high failure rate as long as sleds are selling, and I'm sure that's not just me. At the moment – and keep in mind I'm not the biggest power user – I'd probably be buying a 600 and giving it a couple seasons before jumping to the 850 if it turns out to be as good as they promise.

That said, the fact that they've developed a new engine instead of just maxing out the 800 is promising. Again, that's a double-edged sword: the more that's new, the more likely teething issues are. Hopefully this time they actually ran through enough cycles of failure and revision that it'll be a decent motor off the bat. That they took some time developing it, rather than slapping together a stroked 800 in response to Ski-doo, does mean something to me. Obviously it's going to take some time to prove to me that it's an upgrade in power AND durability, so I'll just say it looks like a promising improvement to a great chassis and leave it at that.

Don’t feed the troll. Lol.

Reality doesn’t apply there.

3 out of 4, that was the best post in this thread. I'm guessing some sad Polaris rider that had enough of the fix kit jokes couldn't take it? Lol

Any word on whether there will be improvements to the existing 800 such as sealed wiring etc?

Everything is live on the Polaris website.

Specs and all.

But yes many wiring improvements along with a contactless tps. (Not possible to be out of adjustment)

All this to the 850.

No idea on 800 improvements......

why do they need to do their homework when they know the public will do that for them? polaris has been doing that since 1997 why would they change now?

If you're interested in the Ambassador Program Referral, please send me a PM.

I have a little something if you plan to snowcheck.

What if Burandt told you to jump off a cliff?

I don't get what the hate is for, just sharing information. People like you have ruined forums. You're probably one of those guys on Facebook posting barney cat memes ever 5 minutes, or writing "junk" on every post about a sled that isn't what you ride. Get a life

Except horse power, or is it just too flickable to mention hp?

Any number the OEM themselves print I can live without, regardless of which OEM!

....and a hp number without specifying how long it took the engine to reach that hp is useless! If it takes 10s I wont have any use for it in the trees. I want a specified hp number after 0,5s!
