Hey guys, new to the site here and I just want to share my experience with the 850 and get some of your opinions.

 

For some background; I'm a long time Ski Doo fan and rider, currently I'm on a 13 MXZ TNT 800. In my group I ride with a 15 MXZ X 800 (Ice ripper), a 16 Renegade Enduro 800 (Ice Ripper), and a 19 MXZ X 850 (1.6 Ice Cobra). I do most of my riding in NY and Michigan. I'm an aggressive trail rider so I'm fairly confident when I say I push these sleds hard. When I upgraded from a 2003 MXZ X 800 the difference was staggering. Everything was an improvement, from power to ride quality. When the 850 was released I didn't expect there to be the same level of improvement as I saw from when I upgraded from an 03 to a 13. But after my first ride on the 850 I was shocked at how responsive and strong that engine felt. I thought for sure it was going to smoke every other sled we rode with. Boy was I disappointed when I lined them up.

 

So here's the deal. All of the sleds are bone stock. My 13 800 has 5XXX miles on it so it is pretty tired and is the slowest out of the group. The 850 walks around my sled, as expected, regardless of snow conditions. The 15 MXZ was a different story. It hung right with the 850 and in some cases would walk on it. The real shocker however was when we lined up the 850 and the Enduro. The Enduro spanks this 850 up and down the fields like you wouldn't believe. It doesn't matter if its from a dead stop or from a 50 mph roll, in the powder on tight packed trail, the Enduro straight up smokes the 850. I don't ride with any other 850's to compare it to so its hard to tell if we got a lemon. I can't justify that the 1.6 ice cobra slows it down that much. I haven't confirmed gearing but I can't imagine that's the case sine the 850 gets beat everywhere by the Enduro.

 

I need some opinions as why you guys think this could be. Is the 850 a lemon? Did we luck out and get a freak Enduro? Does the track really slow the 850 down that much?

 

I'll admit I'm not a huge fan of the 850's and love the look of my 13. After the impression the 850 gave me I'm putting all new fox zero qs suspension under my 13 and rebuilding it so I can ride it another 5k. I guess I'll have to bust out the Mach 1000 to see if the Enduro is really that fast.

I haven't found an 850 that really impressed me in the speed department but I'm sure others will say they are God's gift to snowmobilers.

Getting 850 Extreme in a week, can only compare it to my 1999 triple 800 Grand Touring :)

I ride the same as you, trail. I have ridden all modern 800's and own a fresh 800r and have owned 800 etechs, still have a 16 gade as well as a 800ho Poo. The sleds will accelerate similarly to 40, after that my 18 850 129 says ba bye. The other 800's out there do not have anything close to the rush of power the 850 has midrange and beyond. I have not spent time on a poo 850, fwiw.

I felt the same way when I got my 18 it wasn’t any faster than my 14, but about 500 miles later it was, not whole lot but I say the extra 15 hp showed up, but like you mentioned I’m not head over heels on the 850 either

Track . Track . Track ! . Last year my wife's sled had a Cobra 1.6 studded two per row . Mine had a rip 2 - 1.1/4  studed two per row . I did a speed run when the snow was heavy and by no means a top speed condition . I hit 106 MPH and hers hit 98 . They scrub at least 6 MPH maybe more . My Rip 2 also pulled side by side with it in a foot of snow . It also heated way more than my sled . And if abused they will not stand up to it . If you can't tell they are not my favorite track . Lol . People will argue some of these points but I have seen the differences . I took it off in the offseason .

 

I came off short tracks as well and it takes time to get use to the G4 in a 129 . At first I missed my 120 . It would carve the turns . But get some seat time and learn to ride it a little different . Set it up for yourself and you will not want to go back .

If you have the 1.6, if you stop for long breaks, be sure and knock the ice out of the tunnel. It will tear up the outside lugs!

Thanks for the reply guys! I figured if the 850 had a 1.25 it would be faster than an 800. Then if it lost speed due to the 1.6 it would be similar to the 800 not drastically slower!

Could be you have a weaker 850 and a strong 800. My 17 850 was a rocket compared to my 13 800, hoping my 20 isn’t a slug feels pretty good so far

The track does indeed slow you down and the gearing is different. 

 

With that said, is the 850 that much faster than an 800 - good question. What I can say is when I owned my 800 ('15 800X) I couldn't wait to get rid of it and get back on another 1200 - which I did after 1 season. 

 

The 850 is a completely different animal. Everything I didn't like about my 800 the 850 has fixed. It's been a long time since I've enjoyed a sled as much as I did my 850. I still consider myself to be a 4 stroke guy, but when it came down to buying again there is another 850 in my garage. 

 

IMO...

Yeah - I like the 850 a bunch.

The XP was the most fun sled ever made - but I liked my XR more. The 850 takes it to a whole different level.

Reading all these threads on the 850 kinda make me chuckle. The 850 was introduced to give the mountian boys a little grunt at elevation. The p-drive increased the acceleration and made the sled fell faster. You guys have to understand it's only 10 hp. more than the 800 etec. 10 hp. does not make the sled 10 mph faster. As far as speed increase usually rule of thumb add 5 hp. gain 1-2 mph. Don't get caught up in all the magazine propaganda. The G4 was designed to change the riding experience as with the engine position and seating. The 850 was a bonus as it was designed to fit the chassis.

I need some opinions as why you guys think this could be. Is the 850 a lemon? Did we luck out and get a freak Enduro? Does the track really slow the 850 down that much?

 

 

 

The 850 is not a lemon, it is what it is.  Variability is always a factor but in the end I don't subscribe to the theory of miracle sleds and complete dogs.  Machine tolerances are far to precise these days for widespread differences.  In more cases it is environmental conditions, difference in sled setup, track selection, rider ability, the list is endless.  In this case as others have already stated track makes a massive difference and the shift to off trail leaning tracks, i.e. 1.5" lugs and larger just provides more disappointment for on trail use when the effect is scrubbing off top end speed.  Want larger lugs?  Accept that you will trade top end performance for off trail capability.

 

Also, my experience with the 800 is with a 2013 and a 2016.  The 16' was a big improvement in overall performance from the 13'.  Don't ask me what BRP did in the 2015 and later 800's but they all ran so much better than any 800's prior to that.  As has also already been stated the 850 was not designed to deliver a massive top end gain with that additional 10HP.  It was meant to deliver better performance across a wider mid-range band which is where the 800 was not a great performer.  The 850 completely solved the mid-range lag or laziness for lack of a better term.  The G4 chassis brings a lot to the table in the handling department.  It is a big improvement overall and combined with the new 850 motor has been an overwhelming success for Doo with most everyone that has tried them.  Not many dislike them.
