Frame break thread?
Another frame break thread is dieing to the bottom of the forum with not one substancial statement from Kawi or a dealer regarding the problem or solution 
Maybe a few months after the the new busa is out and someone smashes a frame good on one I'll take a few pics and start some rumors over on busa.org such as "little 'ole lady was riding this totally stock busa bike very slow and the FRAME BROKE!!!'
Then I'll get a few parking attendants with less than 20 posts to verify it, so it HAS to be true

Bah, the jiggabusa had welds breaking on the subframe in 99 and 00. Frame breakage on bikes is nothing new.

and every product has a failure rate. and around the road race tracks frame breaks are not uncommon. but these people claim grandma was just sitting on their bike with it idling and SNAP their frame broke!

they may have changed the process if they found a more efficient method of production.
anyway, were people bitching about frames breaking when the 12 first came out?

Here at Daytona I saw a big huge pile of frames near the track and asked an employee "what are those about" and he said they are broke ZX14 frames that are being recycled.
I said "ya I heard about this truth on the Internet".

Mine has not broken but I am keeping an eye open...
I just had another really good look at it up on my table lift.. 36" off the ground. The motor mounts are on the main side spars of the frame, above the cross brace that is breaking so, that eliminates loose motor mounts.
The only thing located directly on that cross bracket is the rocker arm on the shock and links. The rocker mount is offset, binding at this pivot could cause torsoinal loads.
"IF " the rocker was to rotate around into the cross brace as the shock is copmressed completely, it would load the cross brace torsionally.
I can't tell for certain if that is a possibility as I am using threaded links, and lowered, so it will not happen on mine, may be a possibility with stock components, but I can not verify.
The rocker arm rotating into the cross brace, or the pivot seizing/ binding is the only possibility I can see other than poor manufacturing.
Ideally they would have checked the clearance at full compression to ensure this could never occur.
If it is either case it is a engineering / manufacturing flaw
I am 99% certain these are the ONLY possibilities.
Nothing else is mounted on that cross brace and the forces on the rocker arm are minimal. It is simply an anchor and hinge point, for the rocker arm. The shock and top bracket for the shock are designed and engineered to maintain the loads of the suspension.
Simply my mechanical perspective .....
Personally I would check the rocker pivot bushing/ bearing for seizure or binding as a first step of inspection on bikes exhibiting broken frames at this location.

I just added a 3rd possibility and likely the most probable cause ...
Binding of the rocker pivot... I editied my last post... read it again if your interested.

I'm just waiting on documention, every brand of bike has broke frames thats nothing new. And no one here thinks 14 frames don't break. Eevery brand and model has broke frames.
But to say it was under normal use when we here have tortured our 14's beyond imagination, is what is so questionable.
I few parking attendants need to post-up more than some words on the net.

Definitely. Something that caught my eye in the latest issue of performance bikes magazine in the section where they're testing the '07 literbikes at nurburgring was a picture of a R1 that crashed and was pictured propped against the guardrail. Back end had the "low rider" look the busted frame zx-14's pictured here have. Thing is it looked to be a grey and black 2002 model. Rider said he was rippin along when he just heard a loud CLUNK and the back end went low and super stiff. He went down and the bike went off into the grass. He was ok. What happened was the R1's frame broke right where the shock mounts. Says he's gonna try to get a answer from yamaha but he's not holding his breath.

we see broke frames all the time due to crashes and abuse. That's old news. But for anyone to say through normal use the ZX14's "regularly" or "commonly" brake frames for no reason or because of poor design or manufacturing process, I call"

the only reason they changed the process was increased profit margin, i'm sure
my wife works at a law firm that represents people hurt by other's negligence, if kaw was ever proved negligent (which hasn't happened) you would know because one of us would own their company by now
so yes steve your call of bs is well founded

It may be a conspiracy, and Kawi is feeding the aluminum recycling community by designing frames that break just by riding the bike

Big DTD:
Suzuki has replaced quite a few GSXR1000, and 750's with broken frames in recent years.
I personally know of 2 bikes with broken frames replaced, and the owners would not talk other than to state their bikes were replaced.
Giving someone a new bike would admitt their guilt in my mind.
Confidentiality clauses, compensation and waivers upon exchange of new motorcycles is the norm when these situations arise... thus class action suits rarely ever come of it.
Not likely to hear or know much of it publicly.

as i said before you can call bullshit all you want but there is 4 around here in indy now that are broken im sure all manufacturers have problems
but this is not an isolated issue I guarantee it and are you guys gonna call bullshit on everyone
kawasaki is fixing mine and my new frame was ordered last week
mine is not under warranty and if it was abuse they would not have fixed it
they clearly knew their was a problem they said they have heard of this before from an extruded weld and didnt ask to many questions
so being a stand up company they are doing what they can to fix it

did you check the rocker bearings, and the said broken frame cross brace the rocker is mounted to for signs of contact like I had mentioned.... just curious.

the frame change saved 8 pounds, which makes me wonder if its lighter then normaly u would think weaker. whatever the case kaw may be considering the savings in weight.

Ok so your frame break is one of the rare ones. A lot of people on this board are from FL., and we heard of 14's running hot. Ours haven't been a problem in the heat. Now we hear of frame breaks. Sure a few break like any bike but it hasn't been a prob here.
Truthfully I'm glad you all set, all the  and BS can cease
