Well, after my Intense ride yesterday, it's time for some rear suspension adjustments. I'm hovering around 200 lbs without gear, and I bottomed the rear 3 times on my RTX after I hit a few good whoops yesterday. The sled is on factory, out of the box settings. Front floats are @ 75 psi, they worked great so far, and the rear springs are on medium. I have a good handle on suspension adjustments on sportbikes, but this may be somewhat different, so I thought I'd post up a new topic for those in the know or in the same boat. If anyone has any advice or suggestions, hit back with a reply and maybe it will turn out as a sticky, cause the way I see it, it never hurts to have too much information. Thanks ;)!
 
Suspension is meant to bottom on very hard hits not all hits but extremely hard ones. Springs are what hold the sled up (suspend) it. Valves are what makes it compress. I was very unknowledegable about suspension until this summer at the MX races where I became friends with the Pro-Action guy. You want to use the full stroke that means it will bottom once in a while. If its bottoming excessivley then it may be time for some stiffer springs but the stock valving in the RTX seem just about right on for 180lb rider. i know im not blowing through the stroke and if anything it could be a little softer so I utilize the whole stroke. The rebound seems good the sled doesnt dance around in back tracks well. I really like the suspension I just have to make it turn better I am going to start with the limiter straps. The weight transfer can be an issue too but its not a 2 stroke sled and you dont have to come out of a corner on the bar use that torque to your advantage your not going any faster when the track is spinning. All in all with the right throttle control the sled turns better but not great Ill keep posting the thing I do to help the handling

I don't think stiffer springs are the answer just yet, so after my next ride, I may play with the clickers and go from there. Perhaps I'll move the spring blocks to Hard and try that, but with all that adjustment underneath, I still believe there's a LOT of room for improvement. I didn't do anything to this sled YET that it's in for, (no BIG air yet) but it's not far off, so keep the posts coming guys, there's got to be someone else who intends to really use this suspension !
 
Try putting them on the hard setting. If your 200lbs you have about 25lbs on me plus gear so you may be sprung a little to soft. Also maybe 2 clicks on the compression that will also make the sled sit up a little higher. I think you can make those stock sprigs work for you I just dont think its the valving
 
Your sled came from the factory at 75 psi for the floats? I think mine came set at 55.

I have yet to put 1 mile on mine, so I could be way off on my settings, but here is what I am going to start at for my benchmark.

-Tighten limiter strap 1 hole
-floats set at 60
-Front and rear skid suspension set at 3/4 max for rebound and compression.

From there my goal is to change one thing at a time to see what is what.
 
NyTrO,
tell us exactlywhat you don't like about yout rear skid AND how many miles you now have on it...


lucky 7,
I feelyou going tobe a little stiff IF youhave no miles on just yet. Back off on your compression. ANd tel lus weret your torsion springs are.

And you guy note the temp ofthe shockwhen you are checking PSI. Also the shock looses a little bit of air each time you check them.

So far, Jeff, after 300 kms, the rear rebound characteristics are ok, I just don't like how it bottomed out so easily ! I'm talkin not even close to what I'm going to throw at it !!! If I can get the rear to soak up the big bumps on landings without bottoming, but still use the suspension to near full travel, I would be happy. I can't even imagine what I would have thought on a standard FX is this is the case, but I realize I need to adjust it to my needs, and there's all kinds of adjustment under there, I just need to figure out how to make it work ! You point me in the right direction and I'll take care of the rest ;)!
 
How do you adjust weight transfer... I am used to the mono shock that has a weight transfer rod that can be adjusted but I don't understand how to adjust it on the nytro suspension
 
coupling blocks......but they are not adjustable...see Ulmer and other posts for upgrade.

seems most are pulling the limiter strap one or two holes.......the rest are playing with springs and shock settings......fun huh.

Thanks. I am a 'husky' 220 lbs without gear so I was going to lean toward the stiffer side. I am not sure about the torsion springs, right now the are on the middle.

55 psi on the fronts are going to give you alot of front body roll thus creating ski lift. I usually stay around 65.

you got that backwards

the less psi the more parallel the A arms will be.
This will give you less ski lift but in turn will cause you to feel alot more of the front end hits from the moguls

you can experiment with this

try running your floats at 100PSI and see how much ski lift you get

also make sure when you are adjusting your floats that the front skis are off the ground
 
Looking for REAR suspension adjustments only guys ! Fronts are a simple adjustment. Thanks !
