I ran a 136 Pro X last year but this is the first real test of the 144 with waist deep snow everywhere and drifts and bowls over 10 feet deep. I can honestly say that longer is better. Great warm up for Wy later this month!

niiiice, theres nothing better than fresh powder. nothing

I rode my new 136 x 1.25 in the powder for the first time this weekend and it was phenomenal. I stopped in a ditch waiting for the last in my party and two Revs stopped a short ways behind me. Last person never came so I hit the gas and pulled the ski's down the ditch, turned around and went back to find the last person. After I got that person out I went back and found both Revs stuck in the same spot. I walked down to help them and was in waste deep snow.

That track makes a huge difference....

Two questions:

Where were you riding? Looks fun.

How is the 144" on the trails?

I am mainly a trail rider. If it snowed in Minnesota/WI more I would definitely ride off trail more but still would need to handle well in the trails.

We were up in the Iron River to Valhalla corridor. The 144 is awesome on the trails with the tipped rail. Rides close to a 121 with a ton more traction on hard back and it flies right over the stutter bumps.

That sums it up right there. I love my Pro-X 800 144". RMK would've been less work, but this thing is awesome all around.

Nice pow, send some back my way.

nice pics.. thanks for the 136 track by the way hooks up great:)

Nice pix...

i'm working on loading up some vids of some off-trail work we did this weekend way up in the Keweenaw... fuggin pow was chest deep in some of the areas I got stuck... i was getting facials all over the place the whole time... you couldn't ride anywhere off trail without powder coming over the hood at all times, unless you were track poaching... this pic might give ya some idea on the depth... i was standing in the trench pictured and i was staring at my trailing arms at eye level, I needed help to get out of it, you couldn't see it in the picture but my sled was directly to my left... i'll get some of the vids loaded up on youtube or something later this eve and post some links...

btw - this weekends ride convinced me that the pro-x is gone and i'm getting a full blown mt sled... i'd rather deal with a mt sled on the trails than a trail sled in the deep stuff...

I'm in the same boat. The ProX is about as good as it gets for powder handling out of a 'trail' sled, but it's time for more track and more powder-specific features. You can have trail riding...

Don't know guys, with the winters we have the short tracks are still the way to go. Just by a used 144" track and either a rail extension or a long track skid and swap out when the powder is steep and deep. Just my opinion.

If I do too much more mountain riding I will be buying a mountain sled. There are some things you can't change (or change easily) like the track approach angle (this is HUGE), running board widths and ski stance. Having heating boards to help the de-icing isn't bad either. For my flat lander ass the Pro-X is a great mix. But if we keep having dry winters and I need to keep riding out west more than once a year, M7 HERE I COME!

You can move the front torque arm up 1" in the ProX tunnel for a lot better powder handling and approach angle. I've also cut out the running boards on my ProX. I'll try to post a pic tonight. It helps shed snow in the pow really well.

That said, these are just measures taken to make the ProX something it's not... a powder sled.

I look forward to seeing the pictures and I completely agree - we've taken a ditch banger/race sled and turned it into a hybrid at best.

With that said, I still love my X.

this weekend it took me 9 1/2 hrs to get to the keweenaw... usually takes about 7.5-8... a few more hours worth of driving in a different direction and i'm in the friggin snowy mt range in WY... like matt said, trail are nothing more than a necessary evil to be dealt with til you get to the next powder honey pot... i started on a 121, been riding the 136x1.75 now for about 3 seasons... the pro-x is a great sled, but it just doesn't suit what i'm lookin for anymore... it was a great learning tool for sure, but all it did was open my eyes to a different world of sledding that I enjoy MUCH more than trail bashing...

My next sled will also be a mountain specific sled. 151" track at LEAST. For the time being, my Pro-X works great though. It will probably be 2009 before I get a new sled.

Here's the running board mod I was talking about. It works really well for snow evacuation, even when it ices and freezes. Just kick and stomp and it's gone. You still get a little towards the tunnel, but it keeps the edge grips clear. That's the most important IMO.

With a 144" with tipped up rails did you have to change the gearing and play around with the clutches to keep the stress off the chain case?

A friend of mine long tracked his Viper and blew his chain case three times in three weekends before he got rid of it for a factory long track sled.


Thanks, Bill

yes you should, but it isn't required... plenty of folks have done it and never changed a thing, i just don't think you get optimum performance unless you gear it and clutch it...

I've down geared to a 1.80 ratio and clutched the sled a bit. In the fluff there isn't any more strain the components, just when your banging the ditches hard. I've got over 1500 miles on the stretched setup and show no signs of accelerated wear.

I don't think it's required, but it certainly helps (even more so with a 600)

I HAVE AN 03 PRO-X 7 WITH A 121, WHAT IS THE APPROX COST AND NESSACERY CHANGES FOR PUTTING A 136 IN IT?

rail extensions - ~90 bucks at tracksusa
tunnel extension - ~90 bucks at tracksusa
136" track of your choice - as low as 300 bucks at trackusa

you do all the labor your self... easy...

THANKS FOR THE INFO. SOUNDS LIKE A MUST DO OFF SEASON PROJECT THIS YEAR. JUST PICKED UP THE SLED THIS YEAR, BARLEY BROKEN IN WHEN I GOT IT. IT IS AWSOME.

There are a couple other things to add to your list that you'll want:

new hyfax - 30 bucks


I'd do the drive shaft bearing while your down there if its got some miles on it... That's another 20. Then it comes down to if you want to clutch or gear the sled at all - but that can be done quite reasonably.

You can easally do it on a budget for $500 but for 700 you'd have an awesome setup.

was for me the short and the long is nice. i had had 136 and 121 sled and they are both great. im going to just buy the 136 stuff with a 2 inch lug next year for going to the UP and messing around in the mountain (rent if you go for the day further from the motel) the niceses part for me is with my big wheel kit already hoocked up to the extensions and the mock speed susepsnion drop and track change i can do the thing in less then 3 hours. you get good at it after taking your skid out 11 time in one week.

What is the reasoning behind the possible need for clutching and gearing?

longer/bigger track has more drag and track weight...
