G4 850 questions

hello,

I'm looking trading in my old sled for a renegade backcountry 850 with the 146 2" lug track.

I need something pretty good in snow and pretty good in the trails.. and I've been told this is the way to go.. I wanted a summit but apparently they aren't that great for a hybrid sled.. I really don't know how much I'm gonna do trail time but deep powder stuff I'm pretty sure.. I've looked up at summits with a 146 or 154 but I feer the Tmotion rear and 2.5" are gonna be crappy in trails... my old FX nitro with a 144 x 2" track was alright...just too heavy for off trail use..

any how, I wanted to know how good and reliable are the 850? I had friends with 800 etecs and they were pretty much flawless except at a certain high muleag the PTO side brearing goes to sh!t when not regreased properly with isoflex and a new seal.

are the 850 in that same boat? I heard they have cured this issue and the brearings are now lubed by oil injection.

so any issues ? exhaust valve? EFI ? over heat ? other issues I can't think of ?

For trail riding and some deep snow playing, the 146 with the 2" lug track would be great. The nice thing with the Renegade is the wider ski stance for trails. I have a 2018 600 summit with a 146 2.25 lug track. The Summit has a 16" wide track. The Renegade has a 15" I have the ski stance set at 37". I do ride it on the trails and it just gets a little tippy in tight curves in the trail with the 37" ski stance. Not a problem after I got used to it. Other than that, it is great on the trails. I am not climbing mountains in 3 feet of powder or bashing through the trees and side hilling in the middle of nowhere. I like to play in the meadows, climb a few hills, and get out on the trails in a foot of powder before they get packed down. My Summit is perfect for the riding that I like to do. For what you are talking about, I agree, the Renegade would be the way to go.

Mine is the old style 600 carb. I have heard nothing but good things about the 850 etec. So far, I have not heard any problems with the motor. People I have talked to love it. My 600 has plenty of power for what I am doing. I had no need for a 850 and an almost 4K price difference. Also, the Summit line is geared lower for hill climbing. The Renegade gearing is much better for the trails. With the 850, you will have more than enough power for playing in the powder. There are some great deals out there right now. I got my leftover 18 almost 2K off MSRP. The dealer did not want to sit on it for another year.

I'm going for a snowcheck and get a 2020... 4year warranty is nice.

the 2" lug track is a 16"wide.. the 1.6 " is a 15 wide. ..that's what I saw in the specs anyways..

the newer XR-S model even has the 154 x 2.5 option.. but I fear that will be a bit rough for trail use.. though a 154 x 2" is also available.. it's still kinda long for turning in curves.. I'd have to try one out to be sure of that..

get scratchers if you're going to be trail riding much.

I have the 2015 BackCountry with the 137" x 1.75" track. I can feel it drag after a while of riding on hard pack and will dip into the soft snow as much as I can. I've gotten stuck twice on this machine in 3 years of riding. Once was when I was riding along and fell down into a creek bed. It was about 6' down and the snow was about 5' deep. The other time, my ski hooked onto a bush while coming down off a mountain. Made me famous for getting stuck while going down hill. I'm sure there is a youtube video of it somewhere. Had about 50 people watching, and I saw a lot of smartphones pointed at me.

I ride this to my cabin, which is a groomed trail (by Alaska standards). I don't have scratchers, but really need to get some. 1.75" is the maximum lug recommended for trail riding. Newer BackCountry sleds come with the 1.6" with optional 2".

BTW - The failure rate on the 850's since they were introduced is less that 1/4 of what the 800's experienced in the previous 2 years. So while some have failed, it is a lot less than the 800's. That is going by the number of warranty claims of 5 dealers. Small sample, but at least it is something.


No manufacturer will ever release the true numbers of warranty claims. Those type of numbers can be used against you in many ways, but most importantly, Marketing.

Agree with Bear on the scratchers. Mine did not come with them and need to orders some. So far, I have been OK on the trails. I just jump off in the powder as much as I can.

For trail riding, I agree with you, a 154 is to much. I have not looked at the spring ordering, so I did not know the 2" lug was 16" wide. Someone here did the calculations. Thye came up with that the 146 16" wide was the same area on the snow as a 154 15" wide track. That was another reason I went with the 146 Summit. I have the same amount of track on the snow as the 154, but with the shorter track for when I am on the trails. I just don't need the 154+ length track for the type of riding I am doing.

Your plan sounds like you will have a great sled!

Yeah the compromise is there.. have fun in deep powder, good trail riding sled and lightness of of a two stroke...146 x 2 sounds like a plan !

Spoke with a co worker who owns one with this setup and he follows the summits 154 almost everywhere.

well I pulled the trigger.. but not as planned.. found a strange sled at an incredible price so I had to make the jump.. a 2017(18?) prototype freeride 154 which was used by ski-doo to do I don't know what... it seems to be the first 2018.. but built in December 2016...the VIN ends with 000001 ... it'S white like a 2018.. it has very low miles..and get this : it has the shot starter on it.. so it's not a disguised 2017...im picking it up on Saturday. very clean and has a new track.. odo is around 2000 miles. the actual owner bought it from BRP himself last year as he works there and has great rebates.. all he did was put a track on it... it had a 3" lug track, now has a 2.5" lug challenger extreme track on.. that's the only thing that I don't know how it will react since I would assume the gearing won't be optimal.. though I only plan the use it off trail most of the time..

I don't know if it has the updated engine mount or Pdrive with fins in the back to cool it better ?

gonna know more when I pick it up


anything I should do or check for when I get it ? I would assume clean the clutches and put fresh oem sparkplugs on it ? anyway to see if the engine mounts are the upgraded type ? it'S officially a 2017.. but since it has all the looks of the 2018 and has the SHOT starter on it I dunno..

Just a note about prototypes from Skidoo, usually they do a complete rebuild of the motor before selling it. If an employee bought it first, they would have rebuilt it for him/her. Main reason they do this is to make sure they removed any mods they put in. Now, that was the policy back in the 80's and 90's. Not sure if they still do the same thing now, but I would guess they do.

Should be a good sled.

Wow i hope so !

They rebuild or put a new engine ? From the pics it doesnt seem new.. must be rebuilt..if ever

Either way its pretty clean.. the only drawback i found is that it has no decals

Prolly used to test things i guess..so no decals needed for that.

Im gonna order some next week with other goodies...

Any soecial maintenance on the clutches?

Should i get myself a puller for it ?
