'07 RTX Broken Limiter Strap

[Eh Pex]

The bottom 3rd of my left strap is gone...bolt,nut and washers are gone! Anyone else have this happen or any theory why? (The bottom of the strap is awfully close to those inside lugs).

YEP,same as my buddies 07rtx....I figure the strap is swinging around and track driver nubs are rubbing and wearing strap out....

I had buddy tighten his to tightest hole,this should reduce chance of it swinging around and wearing thru again.

Hey Dan...are you thinking that when the suspension compresses, there is enough slop in the strap so that the bolts/nuts @ the bottom of strap could catch the lugs and tear it? By the way,thanks for the handwarmer research. Please post the various settings and such that you and your bud are finding that work with the '07 RTX.

yeah i think the straps are too loose,and when you lower the front of sled to where it truly rails,they are so loose that they get turned under and track catches them and wears thru....

I think tightening them to tightest hole should cure this...but keep an eye on them after you replace with new....see if it cures...hopefully being this tight youll still have enough transfer..should be OK if lowered somewhat in front and leave rods at max.

Are your limiter straps on upside down? The adjustment should be at the top. If the slack is at the bottom the strap could be pulled under by the track.

How did you lower the front of your sled likr that? I have my strap pulled up tight and the ski spring backed all the way off and it doesn't sit like that.

LOL,no they are installed correctly..the adjustment holes are at top...the "slack" is neither at top or bottom...the ENTIRE strap goes loose when sled sits flat on ground,this is normal.

I think the bottom of strap is getting pulled around into track drive lugs,then it wore thru strap quickly...one is being warrantied and other is close to needed new as well...

tightening to tightest hole(2 tighter from stock) should NOT ALLOW the strap to get pulled into track nubs...we hope.

you need FOX FLOATS and about 15lbs...that is ONLY for radar day...LEVEL A arms are where the SWEET SPOT is for an amazing cornering apex(yet still enough front travel),flat with no skilift....add a 13mm sway bar and you got a true railer.

We will have to come up with a better fix than tightening the straps. I am not going to sacrifice the ride set up that I like by pulling the front of the skid down!

How many 07 RTX's have had an issue?

I have 1300 miles on my 07 rtx ,i lossened them up 1 hole at 500 miles to get the front end lighter they still look ok.

when you lower front of sled you dont need them so loose,it wont hurt ride at all....

If you run the front real tall,it will have bad skilift...like the way they come stock,...or you can try to make another hole at bottom to make it TIGHTER around axle,so it cannot spin on it...that might be something for you to try.

This happened to me on my 05 Vector within the first 200 miles. I identified the problem as too little rebound dampening thus causing the straps to "snap" back into their extended positions and ulitmately failing. I dialed out transfer to make sure that the shocks were working together more to dampen out the extension force of the springs. I also added more rebound dampening to my shock by revalving the center and replacing the rear with an Ohlin clicker. Your RTX rear damper should be adequate and equal to my replacment Ohlin.

Finally, do not over tighten the bolts and be sure that the smooth edge of the washers are facing towards the rubber strap. Remember that all sheared material (like washers) have a rounded edge and a sharp sheared-out edge. If you mount the sharp edge against the rubber, it will dig in and weaken the rubber.

Since I made these changes in 2005, I have not broken another strap again in over 3,000 miles.

Greg

GREG,this is different issue...not near the washers at all,the strap is getting tugged under into track...not near washer.

Made my own straps and installed them today(used the good strap as a template). Cut all the holes the same as original except where the strap goes around the bottom shaft...shortened the distance between those two holes so that when it wraps around the shaft,it will be tighter and the strap can't rotate(and get caught in the lugs). Looks promising. It seems that yamaha used rubber tubing as a spacer on the bottom shaft between the straps themselves and straps/rails to keep the straps in position...the tubing between strap/rail was curled inside of itself on the side where the strap was broken. This might have allowed the strap to move over and when the suspension compressed allowed the strap bolts to get caught in the lugs.If the tubing was to be a spacer, wouldn't hard plastic be better?(can't roll up onto itself or tear or get squished). I'll let you guys know how it all works out.

Sounds like you got the fix..great job...this is exactly what i felt was needed too!..should be good to go!
