Nytro Bent Front End this one has hit nothing WITH PICTURES

What, do you have something secret that you don't want to share??
'08 Nytro, can you tell where the weak spot would be on these frames, and where it could bend??
 

hell just look at the metal where the lower a arm mounts to, its paper thin and has holes cut in it. I think a couple re inforcements on the lowers is all the set up needs. Its easy to see how it could twist back on a lite hit.

I can't tell honestly if my A arms are bent or subframe until I get it apart and measured.

I have a feeling its the subframe, and here is why.

I've been storing my buddies XRS for him in my heated garage because he wanted to thaw out the sled and make some suspension adjustments. Last night i decided to size up the front end of the XRS which is virtually indestructible (you'd understand what I mean if you saw him ride). Anyway, the setup is quite different. The REV's A-arms are much thinner, especially the lower A-arm. Obviously the mounting points are much different with the REV a-arms being mounted further back and angling forward. The Nytro seems to have the opposite approach, the a-arms are mounted further forward and angle back.

I'm no engineer, but the Nytro A-arms are very strong and the location of the sway bar on the lower a-arm serves as a brace for the arm. I think it would be very difficult to bend that a-arm. The sway bar is mounted to the rear of the a-arm on the Rev. I think the a-arms are stronger than the subframe, and because they angle toward the rear, any impact or excessive stress ends up being bending the sub frame instead of an a-arm I'll bet there aren't too many bent a-arms this year.

I'm really hoping Yamaha can figure this one out. I haven't had it happen yet, but I really feel for the guys who have.

Keep smiling, when they figure it out, you'll have an awesome sled once again.
 
Mine is at the dealer awaiting diagnosis by the Yami Rep, I just want it back for the weekend.

Put it this way if it can't take the 1-3' bumps like they advertise it to, then they are not ready to adverise it to be a ditch banger plain and simple.

I have contacted my dealer filed a complaint and have a yamaha rep coming to view my sled on monday. I am doing my part to resolve the problem.

I will also get pics for you nate on Sunday night of the bottom of my sled provided I have time. I believe from looking at it that the subframe is bent not the a arms themselves but I cannot say forsure until I have the plastics off the front end.

Did the rep come and look at your sled and what was the outcome. I saw my right spindle flex back 3/4" on Saturday night when my carbide got hung up on the edge of the concrete floor pulling my sled in the garage. it is at the dealer now having the front end checked for alignment, they swear that they have NOT heard of any front end issue?? I would be interested to know what the REP said ????
 
This was the same issue on the rev's. The sleds are soo good in the bumps you can ride them faster into wild terrain, this gives you a false sense of what the sled can really handle.

You might not of hit anything, but I'm willing to bet you went over some narly terrain you shouldn't have.

I had to straiten and reinforce the REV when I had it and I have a few buddies that did the same. And I'm sure the XP is no different even tho the claim its stiffer.

Also, did you check all the hardware in the frame after the first ride, sometimes it backs off and needs to be tightened after a few rides.

I'd say loosen all the main frame hardware, pull it back into straight, the best you can, and tighten it all back up.

THEN RIDE!

2 cents worth from a site newbie to a VIP MEMBER. gotta love it.
 
Granted you make good points however I don't see any narly terrain on a groomed trail as flat as a highway. Its been in and out of my garage onto an enclosed trailer and off loaded and headed for the trails. I have ridden though alot worse conditions then this nytro has ever seen and never once have I had a problem on a rev sled. Or my RT mach Z chassis for that matter or my apex. I am forsure convinced with the number of these happening more and more each day that it is a fault in the machine. Look at the apex forums they were not filled with these kinds of posts from us same riders who now have the nytros.
 
Soo if thats the case whats our sleds built for they are extreme trail sleds ....ditch banger .. thats what they sold them to us as ......so narley is exactly what I expect .

I honestly believe these issues are from the faulty ball joints and shock loading the front of these sleds ...
 
well my buddy replaced his lower a-arm that had a crack in the paint indicating a bend and it changes nothing. The top arm looks fine, but the subframe has to have bent some cause the arm looks fine. The ball joints have some play in them as well. His spindle is still standing straight up, he said he is just going to ride the thing for now ( its off about an inch). He doesn't think when he ran off teh trail it hit very hard but who knows. I have to agree, the lower mount for the arms isn't the weak point, its the top mount.
 
So what you guys are saying is the bottom a-arm mount is not moving back, the upper a-arm mount is moving forward??? Guess that would make sense- the lower ball joint would be the pivot point between a force pushing back on the ski and the upper ball joint...

So far mine is fine but I think I will pull the plastic off and take a good look at it, maybe do some preventative maintenance...
