Nytro MTX SE Fox Skid mounted on XTX 144" Rails

[m.schuey7]

Finally finished this project, wasn't too hard. Found a 2010 Nytro MTX SE skid for sale and purchased the whole unit for $450.00 My goal was to get rid of stock saggy XTX rear suspension and at the same time save some weight. The front suspension was a direct bolt in, very simple. The rear assembly took a bit more time as I had to swap out the top bogey wheels (MTX Wheels are 1" taller so needed to retain XTX top bogey) also had to find a suitable mounting point for the rear section of swingarm. Wanted to keep the rear ride consistent with the JRE XTX Skid Kits lower rear ride height. Once it all was together I was impressed with how plush the rear suspension feels, also has very little sag. Total weight savings was 12lbs, not as much as I was hoping for but weight savings non the less. Also have rear ride height adjustment now which will be nice for future tuning. post some pics shortly

Looking forward to seeing pics!
I got rid of rear sag with a set of 1900nm springs from ulmer racing. Stock springs were 1400nm I believe for 09, much better with the heavier springs.

Nice work. Interested to see what your thougts are.

Thanks Korey,
Might be able to ride here in a couple weeks as the weather reports snow in the hills Sure feels good to just jump on it and and bounce it, much more responsive than the stock XTX shock and spring set-up.

Couple more pics,..... snowing here finally so might be able to ride it soon,

Excellent, very excited to hear the results!

Very cool setup!!

That's how Yammie should have built the XTX...or at least with conventional arms....the transfer rod skid was a poor go from day one...

So the SE parts bolt right up to the XTX rails....no drilling or fabing required? Other than swapping the MTX wheels ??

So if a guy was buying parts to do this to an XTX he would need the shock/relay rods and associated hardware/upper and lower scissor arms?

Did the new holes in the tunnel at the rear go in the existing reinforcement plates or need new plates?

So all the parts from a SE rear from the shock to the rails then...minus the upper wheels being reused from the XTX...correct??


Great setup!! thanks

Be very interested to hear how it performs.....
Transfer/ride etc.

I have a shorty that I have been hedging on extending and if so how to go about it...
Rail extensions, xtx skid swap, onother brand skid swap, Tamer skid etc.
This setup looks pretty cool, decently light, sturdy and sano.
And I would end up with a better approach angle and tipped rails.

Terez,

Yes, Bought a 2011 MTX SE skid used and basically bolted it directly onto my XTX Rails, didn't drill one hole. Like you said I had to swap the top MTX wheels and find a lower mounting point for the rear mount of the rear suspension. Study the photos and you can see what I did there. The front Skid mount is in the stock tunnel hole, the rear one is reinforced and is part of the JRE re-locate kit. My ride height is almost identical, almost no sag now and 11 pound weight savings. Hopefully be able to ride it soon but think its going to keep the skis on the ground better and ride smoother in the bumps.

Finally rode the new skid last night in zero degree weather, groomed trails that were soft and rough.

For starters everytime you get off the sled its not sagging in the rear anymore, the rear rebounds back up to full ride height every time you step off the sled, even with the tunnel iced up. In the rough terrain corner "throttle on" exits the rear suspension stays smooth and planted, the more throttle the smoother over the bumps. Throttle on transfer seems a bit better than stock but hard to tell as I have a blower now and the sled is light on the skis during acceleration, doesn't seem excessive though.
The ride is definitely smoother all round. I purposely hit some rather large whoops while accelerating and wasn't able to bottom out the suspension although it did firm up progressively towards the bottom of the suspension stroke. Overall I'm glad I did it, improved the sleds ride and performance, most notably in the rough terrain while accelerating.

That's weird, i'm planning to do the opposite, a xtx skid under a MTX because the mtx skid with the fox is the worst thing I ever ride in my life...lol I just send the fox for revalving yesterday, it's the last chance this sled have!

Garnotte,
Probably depends on how you ride and where you ride. I'm an aggressive trail rider. For these conditions it definitely works better than the Stock XTX skid suspension. Smoother ride and better "stiffer" dampening, the faster and bumpier the better it felt. The stock XTX would always bottom out in the rough fast stuff. And the sag was terrible especially when the tunnel was iced up.

If you want to purchase my XTX suspension send me a pm and make me an offer. Only has about 2500 miles on it.

I really like this I might have to do this. It's alot cheaper then going timbersled to shed weight

Yes, and the people I spoke to about the Timbersled sled skid all said that it wasn't suited for high performance trail use. (which it wasn't designed for so not surprised) I was also looking for a solution that didn't break the bank, saved weight (although not as much weight as Yamaha claimed....Surprise surprise) and was reliable. Everything has its pluses and minuses but this is definitely a good upgrade. The largest draw back with this generation XTX is the stock suspension, once you get it sorted the sled is very nice.
