HP numbers are so irrelevant in the snowmobile world. The Axys gets up on the snow so much better than the XM does. I think the Doo is a great sled but it's transfer is not so good. I've ridden with some guys who can ride them very well and it never fails...the Doo is trenching through the snow while the Axys pops up. HP is always important, but there are too many other components that matter too. Doo would be wise to change up that rear skid/suspension setup.

I ran a 2013 XM and a 2014 pro RMK side-by-side for two years. The XM had an Roosterbuilt clutch kit and the RMK had Kurt's gear down kit and clutching. Other than that they were both stock. I can tell you that the lowly 145 HP RMK would consistently out run and out climb the mighty e-tec. Seat of the pants the e-tec felt the strongest, but by any measure on the snow the RMK was would pull away from it. Numbers on a dyno don't tell the whole story.

Noticed similar results with my '14 cat and the '15 pro in our group. Hopping from one to the other, you'd think there's no way the poo would run with the cat cuz the cat feels a lot stronger, but running them side by side they're pretty much dead nuts with eachother.

A person really needs to ride the sleds on the same day. I haven't been on the axys yet, but I have lined my 14 stock pro up against stock xm and stock proclimbs and we either tie or I win by a little on uphill climbs. Rider weight and setup has as much to do with performance as horsepower (within reason).

He's riding wheelies up the side of mountains while I am giving it my all to 2/3 as high as he goes.

Thanks

The Doo T3s have the weight bias toward the rear, that's why they wheelie so much. Buddy has a race car scale kit (4 individual scales). The stock T3s he weighed had something like a 48% front to 52% rear.

My '16 Pro-RMK 163 was around 57% front 42% rear. A turn or 2 tighter on the front track shock and it's now around 52 front 48 rear.

None of the manufacturers state hp. Everyone of them quote what a independent dyno has gotten. Ie dyno tech. That way they can't take the blame.

Thanks to all for the info. I would love to get out and ride one, but cannot seem to find anywhere in Alaska that demos the Axis. I did get out on a '13 Ski Doo and didn't like the ride compared to my Pro, but I have been on it since 2011, so I am sure it's just what I am comfortable with.

If it ever snows in Seward your welcome to take mine for a ride.
I only have the 600 but it's in the axys chassis.

I wouldn't sweat HP numbers. Last Sunday we lined up on the hard packed field, since it hasn't snowed in a month, and did some drag racing. The bone stock Axys was leaving the big boys on the line. We had the stock Axys, a modded 200hp M1000, a turbo'ed intercooled M8 and a turbo'ed XM. The tubos are faster on the top end after 60 mph. Before that the stock sled was spanking those big HP machines pretty badly.


At first I wanted no part of it because I figured I would get creamed but the Axys gets up and goes. I don't care much for straight up hillclimbs and the Axys would get beat by those sleds in that venue but in the trees and tight stuff, there is nothing that can hang with the Axys. Nothing I have seen anyway, including the bikes.
