what happened?

check out my shock here. landed no harder than usual on a 75' table. nothing too crazy. any ideas. its off a '07 450 with like 35 hours


What the! That's not good. I think what actually happened is your rear shock split down the middle.:thumbsup:

thats crazy!get your wallet out cause thats gonna cost some bucks to replace.

I'd say thats worth a call to your Yamaha dealer. Your bike probably isn't under warranty, but Yamaha still may help you.

Did you adjust your spring with a punch/screwdriver and slip and create a weak point on the threads not knowing it?

wow man!! :thumbsup: I wish i could even take a guess at how that happened but i wouldnt know where to start. Did yamaha change teh material for 07? I really cant think of an acceptable explanation as to why that happened.


I've never seen ANYTHING like that happen on a shock, from any vehicle. Looks like it's a faulty shock body. I'd take it into the dealer and see what Yamaha will do. This could be a serious safety issue, if suspension parts are breaking like that. There could be a recall coming (or maybe you just got a shock with casting flaws or something like that).

Take it to your dealer and see if Yamaha will help you. I don't think there will be a recall since I have never seen or heard of this happeneing to anyone else and the '07s have been out for a year now. I think your shock must have had a flaw in the metal.

Wow (like everybody else says), never seen anything like that.

Definitely take to your dealer and "suggest" that Yamaha's district rep needs to look into this, get you a new shock, etc.

The dealer is probably going to be on your side in this, because this looks like a manufacturing defect in the shock body. Don't tick off the dealer; instead make him your ally in this.

If he's not interested, well your manual should include a phone # for contacting Yamaha directly.

Did you adjust your spring with a punch/screwdriver and slip and create a weak point on the threads not knowing it?

unless he's got a jackhammer, that wouldnt cause anything.

yeah i dont think i weakened the housing by adjusting the shock collar. i already have a new shock.....just want to know the cause of this so it doesnt happen again. i dont really want to go through the dealer cuz they suck.

That really looks like a split from too much oil being in the shock. Something liek it not being properly bled. The liquid cannot compress and looks for any possible way out...It found one.

Perhaps someone had too much Saki before going back to his station at the KYB factory?

I blame the factory because your bike looks so clean it does not look like it has been ridden enough to need the shock oil changed.

I would post the picture in the suspension forum. There are a lot of guys there who would help you.

i think you should atleast attempt to be reimbursed for this. I too dread going to the Stealer because they never show any sincere concern. But that is the most legit complaint if ive ever heard one so its worth a shot. Good luck. Glad to hear you didnt get hurt because of it.

      Hey guys I just bought a bike last night. So the seller said the bike will turn on but then die. We didn't try it because it was really late at night and it was raining (seat was wet). But he said if you bump start it, it will turn on and ride. So what do you think the problem is? I just want to make sure it runs... I probably won't be able to bump start it till Saturday (rain)... It's a four stroke, and I know absolutely nothing about them. Thanks.

      I could use some feedback, My son is getting into off road riding so I have starting getting back into it as well.  We mostly do trail riding but did some MX track riding last year and he loved it andso did I.  I have a 2003 TTR 225, it's nice that it has an electric start but the suspension is too soft and it doesn't have enough power for my liking.  When I was riding the MX track I was having issues bottoming out on the larger jumps.  I want to change to a more off-road capable bike.   I won't ride it much and don't want to spend a lot of money, I think I prefer a 2 stroke, when I was younger, in 1990, I raced an 89 RM250 and loved it.  I am looking at a 96 RMX 250  and a 98 YZ400F, both bikes look to be in good condition and around a thousand dollars.  I like the RMX because I think kicking a 2 stroke 250 should be easier than a 4 stroke 400 and the simplicity of the 2 stroke engine.  The 400 sounds good because of the low end torque I assume it has but the cost of rebuilding the 4 stroke if needed worries me and I have heard they are hard to start. Should the RMX be decent for an occasional trip to an MX park?  Any thoughts on these two bikes?

      Brand new, still in the packaging Lexx end cap fits the stock muffler of 2006 & 2007 YZ450f and 06-13 YZ250f. Comes with a forest service approved spark arrestor and two different size tips. Don't spend hundreds of dollars on a slip on, this tip can be quiet and forest legal or loud and make power! Also a note for WR450 guys: get this tip and find a used 06/07 YZ muffler, fits directly on 09-15 WR450. $80 shipped free to the lower 48. PM, call or text 406-223-8789

      So I have a 2008 yz450f and I would like to add some LED lights to it to make it street legal. Mainly just a headlight and a tail light and turn signals if I need to (which where I live hand signals work).
      So where I need help is getting power from the stator to a battery. Wiring from a battery to anything else I got and understand and don't need help with (but recommendations are welcome). So my questions are.
      What type of power is coming from the stator. AC or DC? Will I need a regulator or rectifier? How do I wire something from the stator to charge a battery? What would that wiring look like? Would this stator http://www.rickystator.com/product/stators/yamaha/yamaha-yz450f-35-watt-lighting-stator-assembly-06-09 work? Anything else I should know? Any help would be appreciated. Thank you.
