Very nice photo log of your RX-1 progress.
Wasn't it you that provided me with the skid measurements when I installed a Nytro MTX rear skid and track under my sons Mountain Max?
Thanks again
Frosty
Yes it was - I hope it worked out for you guys
Thanks on the feedback on my thread - I don't have the heart to sell it
You have had your "affair" - now it is time to come back home to the dark side - LOL. Buy a Nytro 162" SE and boost it from day one and be done with it

TT, that's exactly what my wife and daughter are telling me.
I installed the BDX two wheel kit to the rear axle on my RX-1 today. It looks wicked! Nope, I couldn't bear to part with mine either. I should have my snow eliminators here next Monday.
I guess I was looking for something a little different in a sled this time around. I was kind of wishing Yamaha would say "we can't let Skidoo have the entire direct injected two stroke market" (like Skidoo did with Yamaha and the fourstroke market) and Yamaha would actually design and build a real no kidding mountain sled.
Every Yamaha I have had and used in the mountains has been based on a trail sled. The Mountain Max (700 SX), MSRX (SRX), RX-1M (RX-1). I was just looking for something truly lightweight and truly designed exclusively for the mountains.
I guess you could say the M8, D8 and XP8 are all based on their respective trail sled donor as well but, at least they are closer to what I'd consider lightweight.
I'm still watching and now I have the "Blessing" from the family to buy a Yamaha. Now if they'd just make a sled that interests me and one in which I don't have to train myself to learn to ride again. I'm sorry, but it seems to me that I should be able to jump on a sled and have it feel completely natural, not foreign. I guess I need to spend much more time on a Nytro.
Take care

You're right about the steering on the Nytro feeling weird. The steering post is not as vertical as it is on most sleds. This causes the bars to sweep at an unnatural angle. You get used to it, but it still feels strange. I don't know about the 10's, but the MTX's used a stupid, non pivoting riser block that actually forced the rider further back on the sled. OFT offers a nice kit to put the steering post at a more vertical angle.
Funny you mention the 2-stroke smoke and stink. This season when I started the 600 MX-Z we've got, I was annoyed by the exhaust cloud since I've been riding my 4-strokes almost exclusively for the past few years. It is hard to go back. But, light weight is nice and I could instantly feel the difference in weight while both riding and lifting up the MX-Z. If I was going to build a sled specifically for boondocking in tight woods, deep powder and small, steep hills, it wouldn't be a Yamaha 4-stroke. I'd use a Ski-doo TNT as the base and long track it. While the Nytro is capable, it is heavy and the ice build up in the tunnel from the exhaust makes all the Yamaha sleds even heavier as the day goes on.

After 2 seasons with my Nytro and 5 on my Rx1 I still enjoy both sleds. If I was to do only 1 mod to the Nytro it would be the steering post. I built a new cro mo post with a pivot riser and it totally cured the goofy Yamaha setup.
This year I did the Impulse midmount turbo conversion on my Rx1 and it is a totally different sled. Besides the ridiculous power it makes the biggest change is going to the 03-07 Rev fuel tank. When I had both fuel tanks sitting side by side it was painfully obvious why the Rx is so front heavy. The Rev puts all and I mean all the fuel weight behind you where the stupid Yamaha (read trail sled tank) makes you carry all the weight in front of you. The turbo conversion got rid of the top heavy front mount I had and moves the turbo down and back but the biggest factor IMO is the fuel tank. I haven't had the sled on the scales and I likely won't bother cause it is what it is but I'd say I added weight doing the conversion but it rides much lighter. I really noticed a difference on those single track whooped up trails into the alpine where before it slammed into the whoops now it allows the front and rear suspensions to work together becasue the weight is spread out evenly. Obviously Doo figured this all out when the designed the original Rev. A full fueled 163 XP comes in at 541 lbs which is only 40 lbs lighter than a 7 gallon fully fueled Nytro so it isn't that much weight.
My new advise/credo is don't worry about the number but worry about how the weight is distributed over the sled.
As far as rider forward goes again IMO

Once you've gone new school theres really no going back.
