Pro Mtn Air in a 121"

[NyTrOMaNIaC]

This may have been brought up already, but has anyone looked into installing this year's 2010 FX Nytro Pro Mtn Air shock set up in a 121" model ? If these Float 2 shocks are within spec and would match up in length, we could possibly remove the torsion springs for a BIG weight reductin AND save weight with the shocks as well ! This could possibly add up to 15 or 20 lbs less in the rear, and make a more compliant and adjustable ride too ! I looked at them on Yamaha Canada's site, and the shocks look to be quite a bit shorter than Float 2's for the front end, with the front rear shock having an extra volume chamber as well. I think we should look into this and get some part #'s on these shocks. Anyone thinking what I'm thinking ?

yes it is a grand idea but i think you will have to weld braces on to the shock mounts, i dont know if they will be strong enough with out the springs.....but i would love to see it done

Well, they come standard on this years' Mtn sleds, so what would make you think they can't be used on a trail sled ? That new rear Float 2 shock with the XV chamber can hold up to 200 psi, and everyone on here knows how stiff a pair of standard front Floats feel with only 65 psi in them, so that's why I'm thinking they should be able to offer the resistance that the torsion springs would normally take care of. There are also some aftermarket companies out there that offer rear suspension systems without torsion springs. Myself, I'm getting specs on the shocks and looking into it while some continue to complain about too much weight and a terrible ride.

Enjoy your Jello

There's an imagination run loose....

As much as I like the idea of the weight savings and control the air shocks might bring, I have my share of doubts as well.

The mountain suspensions do not take the beating we're expecting these suspensions to take - at all. I think the comment regarding the shock attach points is pretty legitimate. Because of the extra lengths involved, they also have much more room for stuff like this.

All that aside, if somebody figures out how to make them work - reasonably economically, I'm all for it. FWIW

Look at team fasts new air shock for the center of your rear skid. They also now have air assault front shocks which are supposed to eliminate all of the weak points of the stock fox floats.

Exactly what I was thinking, and no torsion springs = A LOT LESS WEIGHT !!! I wouldn't be surprised if Yamaha takes this route next year.
