I want to buy a new Pro! And can buy a Assault 155" (with powder track) or a Pro RMK.......the only differences I can see are Assault is slightly heavier, a little wider and better shocks. Is the extra width an issue in the mountains? I'm a flatlander but want a sled that's going to perform well in the mountains and is good in the trees........
Assault vs Pro RMK - which one?

It all comes down to preference. I got a pro and with the exception of the track and ski width have turned it into an assualt. I found the stiffer valving of the assault shocks fit my aggressive riding style better. Spring riding the assault track hooks up a lot better then the 5.1 track.The 5.1 is a good powder track for early season riding. good luck.
I rode my assault last weekend and switched with my buddies pro RMK I can tell you that the assualt is an awsome dicthbanger /hill climber with the 5.1 tack that is what mine has too. It does not feel as light as the RMK in the powder/carving a good deal of that is likley in the set up. I bought an RMK front end to find out first hand if its the width.
Is the clutching and gearing different as well?
My assault always do wheelie.
Its great for a show, but not for climbing.
I dont care a lot, im in Qc and there is no big mountain.

I snowchecked two assaults because of the suspension. I'm having my dealer shorten up the shocks and swap a arms to make it the width of the pro. When I rode the assault I didn't notice any difference really but figured if I was keeping these sleds for a while I minus well set them up the way I want them.
Good question, one that I and others have pondered. I ended up with an Assault so we'll see how it goes.
Here's some pretty good info,

Struggled with this same question last year while snow checking a sled for RM Kueen (wife).
We ended up going with the Assault........ Wouldn't do that again!!
We exclusively ride in the Mnts. The Assault is a wheeling digging machine! We messed with all sorts of suspension set-ups only to still have the same result!
On hard pack, the sled is a climbing machine.. Roads and trails, unbelievable! But that is a very low percentage of our riding. Quite honestly the sled set her learning curve back!
One day she was on my 163 Pro and in a very short time was making that sled perform in ways that surprised us both! That is when I made up my mind to find a solution!
Solution.....
1. We swapped suspension
2. She took that trenching machine of a tractor lug track off the Assault and she installed a Challenger extreme... Yes' "she" installed!
3. We relocated the front skid mounts in the upper hole. This makes the sled much less aggressive and eliminated the wheely issue! There are two options to locate the front skid mounts however only one is drilled out from the manufacturer. RMK-upper / Assault-Lower
We are both extremely happy with the outcome and I am simply amazed at how much her riding progressed after this!

So.... If I was to consider an Assault today for Mnt riding, I would definitely order it with a powder track and locate the skid higher in the tunnel.
IMHO.....?

Went for the hybrid, Assault for the better suspension, with the RMK 5.1 track. Where we ride is 10-20 miles of trail in and out to the hills.. At my advancing age I'm thinking I'll loooove the better suspenders more than I will miss the 1" of ski width from side to side when putzing in the trees...

I think if you look at the weights of both sleds the extra weight on the Assault is in the track. If you change it over to the powder track they should be the same aprox.
This question gets asked a lot. I have a feeling that most of the people that ask the question should just go with the Pro and update suspension according to their budget (which is what I did).
On the IQ it was a bigger transition from the Assault to the RMK, but the softer track option bridges the gap with the Pro/Assault. However, you have a wider front end and shock valving that has different intentions over what the Pro is setup for. That's why I bought the Pro and then bought shocks setup for mountain/boondocking riding.
