Well, riding the prolite I feel i got a pretty good idea of what the mod sled would have been like, but riding this sled answered my biggest issue which was bar position... I will NOT run these silly offset bar setups people are running... just can't stand them... might as well ride an XPI wanted to know how this steering would work for me, and it VERY much did. That was my biggest hangup on the prolite, and this one felt way better... but still had other issues, that again might have been fixable, but I KNOW the XM feels good for me pretty much as it sits (oh yeah and then skis, hood, riser,
) in reality though, I really like the doo out of the box.
My issues with the XM stem from durability... which is something I've been heard bichin about on the cat forum here, but I've got a bit of a theory on that one too:
The lower frame... the part that has bent for myself & a few other people I know just around here, this part was changed in 13, which was obvious by the fact that the oil delete became easier, but we didn't think about WHY.
IMO the fact that I know 3 guys with 12's that bent up the lower frame, which helps the panel assy bend up as well, just for fun... but yet in the next 2 years this hasn't become commonplace (I hear about it here & there, but not like guys bending S modules on doos) IMO the 13 frame must be stronger, which is why folks are finding the 13 & 14 so much more durable than what we saw with the 12.
I actually talked about this 2 years ago and it was a change that cat did but wasn't really advertised a whole lot. I'm guessing because that would admit a problem. The sx guys kept bottoming out the sled right on the cooler so the engineers essentially lifted up the bulkhead in the middle of the sled to help with that problem. Well a positive side effect of this was that it helped the triangulation effect on the front end and stiffened up the whole chassis.
