xm vs pro

[byeatts]

The difference is the poo has a steady supply of lube feeding those bearings, whereas a doo does not.
I really do hope you get 5k+ miles out of your crank. I believe that is over double the average you could expect out of a single application of grease to a sealed bearing spinning at 8k rpm under some pretty extreme temps, but maybe doo has it figured out?

I build Mod motors BB ,s and dont own an E tec. I simply state the facts and the motors are lasting well.all of the 2011 E techs here are issue free with high mileage . Crank runnout is what kills bearings.have many of the sealed bearing cases and trouble free.the Poo oiling system is good as well, fuel washes the oil and thats why it requires a higher dosage.

Ski Doo and Polaris are busy duking it out to see who is the top dog in the mountain segment. Meanwhile Cat is busy competing against Yamaha. that should tell you something about Cat.

Ski Doo wins based purely on reliability. Polaris builds the best sled on the mountain but they can't keep it on the mountain!

Reliability means never breaking down - saw that in a Chevy ad.

Obviously you have not riden or rode with a new Cat to make such an ignorant statement. I guess you are implying the Cat weighs as much as Yamaha.

LOL! Not bashing Cat, just stating a fact! They no longer publish dry weight information, they dropped their 600 and their advertising focus is almost exclusively the 4 stroke! Sounds like Yamaha 10 or so years ago, doesn't it?

 

[snowyo]

The thing is with the reliability thing is ,there are 10's of thousands of doo/xm/xp motors turning high mileage...please dont tell me the same exists for the RMK Pro.(good sled(chassis) about time polaris but shyte motors)

They put the wet weight right on the sled. Dry weight, for the most part is meaningless. They also have the crate weight in the owners manual.

I have a friend with a 2009 Ski-doo that has 6,700 miles on it and he has never touched the motor. Both of my older sleds (2007 and 2008 Polaris's) are approaching 2,500 miles and I am getting nervous about how much longer they are going to last even though they are both 700's. I seriously don't expect them to make the 6,700 mile mark. Does any Polaris owner actually think they can get that kind of mileage out of an engine without a rebuild?

That said, the new Pro-Ride chassis is absolutely amazing! Talk about easy to ride!

I would bet you can double your mileage with the 700 motor. My buddy has one with over 6,000 miles on it.

 

[snowyo]

I owned a 2007/700 polaris and sold it @ 4000 miles and it was still an arm stretcher and never a hiccup...700 is/was in class of its own(literally).

I hope so because I don't plan on getting rid of either one of them for quite some time. They are great extra sleds for guests, family, etc. Both have the2009 front end update and I installed electric start on them. They are kind of a bitch to pull start when really cold! Most of my family has now figured out we own a cabin in the mountains so guests are becoming a regular thing! LOL! That's alright, I don't mind. I am introducing new people to our sport regularly and that is a good thing!

I understand the guest thing, I have a cabin also. I just sold my wife's
08 700 dragon with 2500+ miles on it to get her the 13 600 PRO. I really
didn't want to sell that 700 for the same reasons you stated, not to mention
I think they are probably more reliable than the 600 is.

 

[Vern]

why do ya suppose poo can build a decent 700 that runs strong and will hold together but no matter what they try they can't do it with an 800? hell, they were dam near the same output to from what i understand. maybe they should bring the seven back and toss it in the pro and give up on the eight.

 

[Jaynelson]

I had a 2001 RMK 700 with the non-VES 700 in it. That thing was bomb proof and it went hard. No problem with the Cat, Poo and Doo 800's of the same era I don't care what anyone says. That thing had 5,000 plus plus miles on the original everything when I sold it and the only thing that blew was my fault (Split an oil line and smoked the PTO bearing). I think that 700 with a pipe on it in my pro would probably be just fine...that said my pro motor has been great for 2.5 seasons and it came with the sled lol

 

[snobyrd]

with doo doin all thier advertising in being top in hp, they should be a clear leader, but thier not and that's awsome, if pol decides to put good pistons and high compression heads in the pro, watch out folks...

 

[Devilmanak]

I find it interesting that this opinion is favored here on snowest so much. I ride an '11 pro that just turned 2400 miles on the original motor. In my goup there's another '11 with just over 2000 miles, a '12 with about 1900, and some lower miled '11s and '12s along with a few '13's, all pro 800's. None of these guys in my group have EVER blown an engine.
I only ride with a few guys here and there that own E-techs. They seem to like them quite a bit. The thing that would worry me about running a doo with the mileage that I have on my polaris is the fact that the ski-doo E-tech does not have any oil going to the crank bearings. That's right, no oil! It's a fact! How long can the crank last like that?
How can anyone say the doo has the more reliable motor?

THey will. 2000 miles is the magic mark, anything over that and you are on borrowed time. Saw it 4-5 times in the last year between two of my bud's 2011 Pros and his Dragon. 2200 miles and boom. Dragon twice, the new engine lasted less than 600 miles before the cylinder broke. (3 engines in that one.) One in each Pro, and one of them was already on it's second engine. So 6 engines in a year and a half between three sleds. None of the replacements got anywhere near the 2000 miles that the original engines did.

Here is a short clip between an xm and a pro. clearly the xm rider gets worked. lol

 

[BFisher]

If you look closely at the pro the over structure design came from the IQR..

 

[trinitypowder]

I love these threads..............always entertaining I like Pro's, XP's(havent ridden the XM yet) and I evened liked my T Apex-a little. My current ride, an '11 M8 is just fine too! You can be brand loyal all you want and miss out on the often fun adventure of trying something new once and awhile, but to me, that seems boring. Life is an adventure and so is snowmobiling. Have fun, try new things, and enjoy the ride

 

[turboless terry]

I will know first hand, tommorrow, which works better. I can't compare to my pro because I have a 3 inch track but my buddies 155 is bone stock and so is my buddies xm 154. Looking forward to riding the xm. I have had all the years of revs but am an xp hater. Probably won't post about it because it really doesn't matter. Ride what you like. It will be one sled against one other sled so that doesn't mean that much. I doubt there is a huge difference in climbing. I am more curious on how the xm handles sidehilling and in the trees because I have the pro on a pretty high pedistal.

 

[turboless terry]

The xm is the real deal. I could ride one. I like the pro better but I am used to it. The xm still turns up hill like the xp when laid on it's side. I don't care for that. That was about the only thing I didn't like. Running boards aren't as good as the pro but they aren't bad. As far as power I thought it had more power from mid to top but when we raced them they were so close that it doesn't matter. For the record the xm won 2 out of the 3. It was basically who ever got out of the hole first.150% improvement over what they had. I can't believe how the xm almost sounds like a 4 stroke.

 

[swrev]

Turboless Terry, could you feel the weight difference or does the XM hide the 50 lbs well? What were the snow conditions for the race? Were you running your sled w/ the 3'' or comparing w/your buddies Pro? Thanks.
