First Ride on the 15 wide Extreme

I don't think they make it in a 15 wide for a 146 in a 2.86. Think thats the size that generated my question.

Correct me if I'm wrong, but I thought I read somewhere the Everest 600 with the iron bore carbed 600 was slated to run a 146 x 15 x 2.86 x 2 this season?
 
That would be very "un-doo like". Ski Doo is too in love with the 16" track to not put it on a mountain sled. As for me, no more 16's:face-icon-small-ton
 
Trinity,

How did the 15 effect your ability to carve?

Last week I have the opportunity to ride a Assault and 09 M8. Compared to my XP you could blink an eye and they would be on there side. They both have a 15 wide track. Did the 15 have that effect on the XP?

Thanks
Shawn
 
I just put two rides on the new 2.86 155x2.5x16 extreme! love it so far..
The lugs are all ony 15 wide, the 16 is only on the base and bars??
I first thought I got ripped off, any gain in hight I lost on the sides.
In the field it is proving to be a great track, I'm out pulling my friends 09 163
in the deep stuff.
Any one know why they went with the 15 wide pattern on this track? weight? cost to produce? windage in the tunnel? ski-doo's eating the first 1/2inch off the track anyway so why put it there?
 
I find it hard to believe that a 15 wide is THAT much easier to sidehill. Your rails haven't moved and that's where the track bends from. Your not really comparing apples to apples here either, you went from one track to a completely different track.
I'm not going to say that it's probably not easier to sidehill with the 15 wide but I just don't see how it could be that big of a difference.
I thought doing a 16 wide track was a brilliant idea and don't know why someone hasn't tried a 17 wide.
Not trying to argue or slam you just giving my .02
Good review though and I can't wait to try my camo extreme.
To bad your not closer to MT, I got an SHR840 with a 155x16x2.5, would be intresting to see if there's any difference but I have a Rev so it wouldn't be exactly apples to apples either.

I find it hard to believe as well but I hope it is true. If you think about it the two main points of contact for a snowmobile are the ski's and track. Think about the difference the ski's have on handling... you would think a ski is a ski but NO changing just an angle or edge will make the world of difference!! and then think the track would have equal or greater effect.

Cheers

Trust me Shawn, it whips around much easier with the 15. Sidehilling is definitely easier as well, but to me the "whip" around feeling while on the gas is a whole lot better than the 16. Alot of that may be attributed to the 2.5 lug vs. 2.25 getting more traction and thus reacting better? Either way, the 15x156x2.5 works perfectly for me and my SHR860. I'm sure a stock motor'd XP would benefit just as well! The 15 really "livens" up the chassis. Try it, you'll love it. Like I said before, if the 16 was THAT much better overall, AC and Poo would be on board.

Remember this: The amount of rubber that I took off of my sled with this track swap, is equal to the difference between a 144 and a 151. Not much, but when you consider the amount of "drag" that the 16 creates, it seems obvious that if you get rid of some rubber, the sled will move much easier due to the lack of "drag" of the larger track vs the smaller one. Also, since the Came Extreme IS NOT PORTED, you don't lose any floation at slow speed in the trees vs the stock doo track that is ported.

SnoSnob,
I live in Butte, I was thinking of the same set up that you have. What drivers are you using with 2.5 paddle. Will the 2.86 8 tooth give enough room for the 2.5 track without D&R. I ride a REV also.

What you call drag I would call more footprint. Look at the oldest thing to date to run on top of the snow....a snowshoe. Most snowshoes and long and skinny right?
I really don't believe a ported track loses any floation....unless you turned it into swiss cheese and even then I would be skeptical, again look at a snow shoe. Why would Poo and Doo port tracks if it will lose floation plus I have run my track ported and non-ported and the only thing I noticed was less snow in the skid.....that's it.
All that really matter is that your happy with it.:)
 
I agree that you wouldn't loose much if any floatation. But I do think the 15 x 2.5 would give the sled a much easier whip around feel. especialy when your on the gas.

I have the opportunity to try a 2.5 x 15 so I'm going to jump on it. I want my sled to feel easy to ride. Not to make the highmark of the day. I'll post back after new years when I get the track.
 
TP

Glad to hear your happy with your 15"!!!

Sounds like that thing fits your riding 'style' like a love glove!

I am also exited to try my 163" 16" wide but wont till my D-Shaft gets changed. Plus im working like a dogg too so dont have much time but will during the holidays. Just no Extreme :( Yet!

My ridding style is a little different and I really have no issues tossing my XP around so I think I will be happy. I do more climbing then 'tree riding' but I will keep you posted on my results.

Glad your happy tp!!!

One other thing.

This whole powderclaw bidnass really reminds me of the Mav. Eveyone talked about the mav like it was the best chunk of rubber to hit the snow, BUT that thing is ok but NOT the best track.

My opinion is go with whats proven, not what the media/magazines have to say. The extreme is PROVEN! So Thats why I went with the Extreme.

I am not a beliver that the 15" track is the reason for a sled to side hill better. I can see it whipping around better maybe.

I have noticed that the position of my feet in the footwell is critical to how my sled side hills as well I have moved the skis to the inner stance and removed the sway bar. These 3 things change how my XP handles in a big way.

The other thing that I believe people do is run too much spring tension on the front skid spring. This elevates the sled making it tippy and it upsets the overall handeling of the sled IMO.

I will say that I believe that the XP could side hill a lot better than it does however if I move my feet all the way forward in the footwell it handles a lot better and side hilling is a lot easier.

I believe that the 16" track is more about floatation and climbing than anything else.

Later....
 
I also like to stand futher ahead while sidehilling on my XP. I think the m8 has it going on for side hilling. I don't like how they steer around on harder snow but man are they stable on the sidehill. But when it comes to the most technical riding then I like my Xp. I was sold on it when I went with Mark on a test ride last year and were taking a trail in to a riding area that was all f'd up. The trail went around the face of a hill that dropped away pretty good. Others had obviously tried it and weren't able to hold the sled up on the trail and broke the trail off. The trail was so thin in spots you barely had a flat spot wide enough for the inside ski and most of the track.
I would have never held my Poo on that trail but with my XP I just stepped up in to the foot well and dangled the off side ski all the way around. Whether it was the 15 that allowed me to hold it up or Marks suspension??? I would guess both.
Another thought I had was the 2 wheel kit. My Poo would lay over way easier after I installed it.
 
Recent findings powder claw vs camo extreme 162vs162

Brother has new m8 turbo with 10 pounds boost it is awesome but the imo the powderclaw 162 lacks to my xp with same length and the 2.5 extreme. I use the 16 wide. If you want to totally change the xp sidehill try taking out the swaybar. Adjust shocks up to 5 and it is a new sled for mountains.

The turbo at 62 mph track speed with powderclaw is just lacking traction compared to my 42 mph track speed and 162*2.5 camo extreme. For the TURBO it just bends over too easy and acts more like a 1.75 track the 2.5 extreme is much better. Bear in mind 15 vs 16 wide. WE are in 4 foot of fluff on a foot or two of base. Very dry snow. Paddles are bent over at rest after a run with turbo, maybe better on stock m8.

Just ordered RKT 860 with spare cylinders, have nearly 20 pounds off front with super q can, holz front end and no sway bar. Love the light front on the xp and rider forward. Running stock clutch in clicker 2 at 6500 foot. If Kelsey says super q can it is so. I dropped one clicker with can and lost weight.
 
Nice report Motana man! I'm putting my new Super Q on today in place of the HPS. I figured even though I have a BIG JOHN 860, if Kelseys likes the Super Q that much for his 860's, then I will too. I suspect that powerclaw is better than the attack 20, but still not quite a Camo Extreme, as a good all-around track.
