Swinging arm failure

now im no engineer but all the adventures have wire wheels that are all out of true and not only run out side to side but oscilate quite bad as well and my mate brand new one does this straight outta cannons . coupled with the free play allowed by bmw on the rear drive bearing id say that paralever /swingarm whatever you wanna call it has to take a bloody lot of un natural constant side forces / vibes . if there was a small flaw or a stone hit it etc then surly this would help in the thing blowing its self to bits . i read somewhere that the main stand bangs against it as you ride along . gonna check mine later . just a thought

Mmmmm, you put forward some valid points
 
Only you know why you persist in buying the brand. Why not stop, it appears you'd be well mad not to. Though GS TRV's response may explain why you probably will carry on regardless.

I have a 1150 GS. I wanted a 1200 GS but had heard of so many bad stories, especially from a bike recovery man that I know, that I opted for a 1150 just to try the brand out. I would really like a newer bike of the GS ilk but there ain't a lot on here that seems to be persuading me to do so. At the moment I would consider a late 1150 GSA.

Maybe once I have done a FD bearing on the 1150 I might feel happy to get a 1200 as my mechanical skills might be up to owning one without paying BMW for some extra cover!
 
Dont suppose you have actualy spoken to BMW about this???

I see the usual trolls(with the exception of Rasher) have been along.

This is not a common event, though still an unwelcome one and I am glad you are fine.

Remember people just somtimes, shit happens:mad:
 
:type Dear BMW,

Love my 09 GSA :thumb, to date, 18k miles of happy trouble free european touring ....thinking about upgrading to the twin cam in 2012

However, now a bit un-nerved about buying a new one. Can you supply a new one with one of these single sided arms and final drives..... Kind Regards
 
The fact that this is such a rarity shows that this isn't a common fault (yes I know that's obvious). Sometimes these things just happen, even aircraft have unexpected structural failures and fall out of the sky occasionally. Cars have things fail. No component is perfect, this could have been a tiny bubble in the casting that let go after a certain level of time/use fatigued it.

If we know of 2 of these occurrences out of all the 1200's produced and that's enough to make people never want to own one, then I think you have your priorities a bit skewed.

I'm heartily glad that the OP is ok, this must have been a seriously scary thing to have happen, but I think people are massively overreacting to a rare structural failure. I had a sidewall blow out of a tire on a car that was 800 miles from new while going down a motorway at night. The entire sidewall separated out. Could have been bad, it was certainly hairy, but it would be like me saying I'll never ride/drive anything with tires again.

There are far more realistic things to worry about when riding than whether your swing arm is going to separate on you.

All that said, I hope BMW take a long hard look at it and find out what went wrong, purely from a quality control/assurance point of view.
 
it's certainly not something that's going to keep me awake at night.
 
Wont keep me awake at night either.
Now its up to you whether you go all American on BMW's ass and get a lawyer or whether your happy for a we will repair the damage sir.
 
But talk about an over-reaction from some people

The bikes only three years old. Its not acceptable to have things like that happen on a bike that young.

However I will admit I don't know the history of it and maybe its been abused which could have caused the failure.

If it was an ex Off Road school bike it would help explain the iffy clutch, wonder what the registration is?

Glad your OK TJD1200 that's the the most important thing. :thumb2

Have been up and down the boring A12 on many occasions but wouldn't care to have the journey livened up by an incident like that...:eek:

Thank god it is incredibly rare and no need for any sensitive types to run away and hide from the 1200GS and BMW in general because of it.
 
Lots of speculation...... not sure there's any evidence ..... going to take a better look today in daylight.

Just wona get it repaired now.........

Need a trailer now to get it to the shop................

A letter to Vosa outlining the failure, focusing on the safety implications ... photos etc.
Manufacturers have been known to change their stance, when Vosa get involved.

I wont go into it now, but i was instrumental in having the dash displays replaced on the MG 1200 sport several years back..... so i know that letters to the right people do yield results

Looks to me like an unfortunate failure and I've never heard of it before. Have you spoken to BMW yet? With any luck they will replace it or at least contribute.

I have a U/J go a few years ago which damaged the inside of the shaft casing so it was changed for a new one.

So why feckin comment then:nenau Things sometimes break......get over it:augie
 
Bike will be going to BMW shop next Sat'. Few transport problems at the moment. I have a neighbour offer to borrow a trailer next Sat and we'll do the deed. ....... and so the process begins......fingers crossed.

Looking at the bike's general condition.... and the paperwork history.....(full service history etc... ) It hasn't been abused.....

Nope - ive an 1150 and will be keeping it :thumb2

It probably has happened to the odd 1150 also, but the the intrepid pilot was so resourceful he splinted it back together at the roadside with a 10mm spanner & some duct tape . . . and it's still holding 9 years on! :thumb
 
This should NOT happen under any circumstances and is a serious and potentionally FATAL failure.

BMW UK (not your local dealer ) and VOSA should be made aware of the incident and the swingingarm should be professionally examined

I would assume it is due to a casting fault ( any previous damage on this particular machine that might cause such a failure would be easily visible) rather than a design fault .

BUT what really pisses me off with this forum is those blinkered people who just cannot see that BMW's actually have faults (FD failures ,fuel pumps, gearboxes etc) and if anyone mentions the faults they will slag them off till the cows come home.

They would rather stick their head in the sand or more likely up their own arses and shout very loudly about how reassuringly expensive and totally reliable their precious BMW motorcycle are with no real or perceived faults.
