3" terrain dominator?

[sledneck_03]

By reading some topics, a few guys that got 174 t3s are going to the 154 this year. Saying they dont like tractoring around planted all the time.

I don't think trenching has as much to do with the approach angle as it does the suspension geometry and function.

Pro's float better than older sleds that had shallower approach angles.

KMOD skid floats better and it has a steeper approach angle than the stock skid (when the limiters are all the way out).

Obviously shallower approach floats better all things equal but suspension, chassis, and weight distribution play a bigger factor.

Can you post a pic of the angle on a proclimb, people claim it has a problem
trenching also. Just to see the difference in angle

UPDATE: Added the Axys to the line up.

Here you go!!

Have 2011 Etec XP that had a 163x2.3x16 that weight 63.4 fully clipped, now have a PC 162x3x15 that I clipped that now weights 58.4, also have a new T3 163 track that I am in the process of putting clips on but have not put on a scale,
The 3 inch PC changed how the sled works and responds, The XP has a Tryg
872 and all of the 13-14 upgrades of the XM.

axys looks angled, front of skid sits off ground.

It's all relative to what the chassis will bear as well. Put a 2.6 under an edge chassis and I bet it sucks to ride vs a 2".

i disagree.
but i get it as far as 2.6 would be preferred in the trees, for now.

Be interesting to take those three sleds, put a 200 pound rider on them, bounce the sled to get sag, then see what those angles look like.
I always wondered why the Cats don't have a rounded approach like the others, the track is flat, makes a corner, then goes flat again. It is odd, and has been that way since 2012 at least.

Comparing a 2014 cat to 2014 pro the pro gets up on the snow significantly better and does not trench as bad. I think the rail angle and roundedness helps as well as the tips of the rails are longer toward the drivers. So far the 2.4" 5.1 track has worked better than the 2.6" powerclaw. IMO the 2.6" Axys track will be perfect for most riding.

looks like even steven power to weight next winter.poo just needs a 3 inch.

How?

Ski-Doo T3 155" - 457lbs 160HP (I've seen 155-163)
Axys 2.6" 155" - 408lbs 160HP (I've seen 150-168)

HP is hard to really say, but weight is weight. that's 46lbs difference at nearly the same HP. I haven't seen a T3 option for the Axys so I don't know how much more it will weigh. But Doo managed to put a T3 on without gaining weight.

Funny how the #'s can get blurred!!

2015 Pro 163 RTR 516--2014 Pro 155 RTR 514
2015 163 T3 XM--RTR 537---2014 XM 154 RTR 556

As far as Dyno # I quoted all came from Dynotech Research
Have yet to see any #'s from the Axys come close to 168 that is stock!!

axys looks angled, front of skid sits off ground.

Short tunnel sidewalls on the Axys really jumps out, doesn't it. And higher a-arm mounting on the spindle.

Regarding the trenching, it's the combo of the skid - track - tunnel. Poo has the worst ride, but gets on the snow the best for the same length track, think that's not a coincidence. Doo 174 is getting close, which tells something, too.

The Pro has a larger fuel tank then the skidoo, with equal amounts of gas you can subtract another 6lbs from the Pro.
