Suspension settings, RTX ONLY

[cannondale27]

Are you getting any sag in rear suspension when you get on the sled kerrdog?

 

[Kerrdog569]

Yeah about 2inches or so

 

[cannondale27]

Nice! Will get even more by 500 mi. Sounds like that LE skid is working good.

yeah once I get some miles on and it loosens up I think it's gonna be awesome,i sat on a LTX SE at the dealer the other day and that suspension didn't move when I got on,wow I was surprised by that,mines way softer than that

. Yes rtx in 14 is same stiff suspension as ltx. I am jealous.

The question is, is this 2015 RTX (all models) or is the RR skid geometry/Fox shocks?

Keep in mind at least 3 of us reporting here have the RR skid with the Fox shocks.

Good question.

Has anyone tried the "Out of the Box" Setup for the '15 RTX LE? What's it like?

 

[cannondale27]

Shocks and geometry of RR/LE skid is different than RTX. Shocks help also.

No,mine felt really stiff out of the box

Looks like Cat illustrates this quite well. Note the angle of the rear shock. Also front arm appears to be longer on the RR.

Last piece came in today and finally snow too! Will hit the ditch tomorrow. First setup will be Carver stock rear and then will try the Axis.

I just wanted to add one comment. I see a lot of guys talking about running 50-60 psi main pressure. I've seen Cat 2 stroke guys running 70 psi main. I've also seen comments from a guy that started low for a season disliked it then decided to bump up and found a huge improvement.

Looking at this logically and taking into account personal preferences, I think we really should be looking at a bit higher pressure for the heavier engine.

As a coil spring example: Doo 2 strokes run a 90-95# coil while the 4 strokes run 120# and apparently the sno-x run 145# Now I'm not trying to compare spring rates to psi, but I am looking at the percentage of increased spring to support the weight. Going from 90 to 120 is a 33% increase.

Using this logic we would likely benefit from more psi. Not sure if 33% is the number, but a bit more should surely be in order.

Do what suits you. I ran 60 in main because I noticed at 70 inside ski was not compressing and would lift in corners. Lower pressure helped that and made it plush. I do have push now though but only cause I am cornering faster.
