2021. 1250 shaft failure

I think people are obsessed as you put it with rejecting stuff because that is their right under the consumer rights act. Secondly there is a reasonable expectation that after spending a significant sum of hard earned cash or otherwise the item in question will survive a short ride without falling apart. Personally I would have no confidence in that bike going forward and I would be returning it.

Agree - it costs money for the manufacturer to accept a rejected bike. If we are to encourage manufacturers to improve quality, this may well help.
 
The assumption is that the bike is inherently flawed because it had a bad drive shaft so should be rejected. The overwhelming odds given the insignificant number that have ever failed are that it is a freak issue and is a easy fix with minimal stripping. Whether it fails after 5 mins or 5 months makes it an inconvenient warranty issue not a lemon bike. A replacement bike is just as likely to have another random failure of something as the original so it buys you nothing in terms of potential reliability. At least you know the replacement shaft has been looked over by a tech before fitting. ( and possibly lubed ).

Out of interest If an abs sensor failed would you reject your new car or bike ( because you can ) or just let them fix it and ride/drive off into the sunset ?

The manufacturer will likely never know. If bmw uk give him a new bike they shift another unit for their numbers which at their cost will be more than covered by the resale of the rejected bike. They have no need to involve Germany as the fault was simple and had no implications requiring investigation. If it was a bizarre software issue that stumped everyone that’s different.
 
The point is that it happened on a brand new bike that hasn't even had its first service. I don't know the actual circumstance in which the drive shaft failed, it hasn't been mentioned but could have had a potentially lethal outcome. There are other more well known problems with the 1250s particularly with leaking calipers which to be honest has put me off buying one to replace my 1200lc gsa. BMW need to up their game as they are providing a premium product at a premium price.

I agree that failures shouldn’t ideally happen and the calliper issue dragged on far too long but why does it matter if it’s fails after 5 mins or 5 months. Is the bike less likely to be reliable ongoing because it had a random one off failure today rather than next month ?

If you think the bike has failed because its using poor quality components then how is the new bike going to be better ? The logic of rejection is that your in a better position afterwards is it not ?

What planet are you on? every fault logged with a dealer is reported back to the oem, and then onto the suppliers no matter how stupid! and i mean stupid!!


20 odd years ago when i worked in tier one automotive i was given a batch of dealer / warranty/ & general complaints to investigate and report back on -

costs & liability for defective or damaged parts have to be recovered period!. No one absorbs costs and says nothing !

Ever heard of liability ??

So the part fails and the dealer says nothing --

You need to do some research on liability

I don’t doubt it ends up on a spread sheet but it won’t likely register with the manufacturer beyond a bottom line figure unless it’s of concern to manufacture. If your selling jet engines to Boeing that’s a different matter as they have a habit of falling out the sky so every fault is investigated

I was technical advisor at second level sport in the 90’s who were the uk importer for various brands from mtb’s, skiing gear, motorcycle products amongst others. I inspected all uk warranty claims that weren’t handled by the dealer. ( some parts are handled directly by the manufacturer of that component, and oem is not involved period ) there were no reports to manufacturer directly for claims unless we saw a pattern or issue of concern, just a claim for costs or replacement parts. If your seals blew on a set of forks, the manufacturer didn’t give a rats arse unless 1 in every 10 blew. They look at the bottom line at the end of the year for sure, any sensible business would.

I know a service manager at a dealer in the US. Out of interest I’ll ask him if and what he writes in a fault report for each claim.
 
Hi guys all joking a side , I’m am not a trol bike was recovered from my house today by bmw , it seems the bolt above the rubber gater holding the whole drive together came out and is gone , they are going to sort it out ,will up load a photo soon for all to see

That’s interesting, it’s a locknut as well from memory.
 
Well, hopefully, it’ll be fixed, and the OP will have a bike he’s happy with.

And the dozy twat at the dealer will have some remedial training, as he clearly needs it.
 
No mention in this thread of drive shaft explosions so unlikely to set the resident denier’s teeth gnashing... but, BMW seem to be either -
a) cashing in on a non existent problem or,
b) addressing a long standing maintenance issue.
You choose.

You have to give the resident denier credit - he is not biting:D

Wonder what the dealer will say when they cannot split the drive shaft due to corrosion?
 
I cannot believe a brand new bike with such a defect will not be repaired to newness again.
They may not give you another new bike but they certainly must repair and give you a spare bike to ride until case is closed.

It is a bmw dealer, right? Not AliExpress?
Sorry I couldn’t help myself.

Pete if your shaft failed at 294 km's you should take some Viagra as spline lube won't help...:D
B.t.w. my friends R1200GS as 91 000 miles on his shaft , that is roughly 145 000 km's and still no shaft failure :thumby:
But he would be on your 5 th set of chains and sprocket$$$ and lots of lube...:(
But I hear BMW offers a chain now on S1000RR,R,XR that will last 20K miles without lube...
Chains are for old Ford Model T's and bicycles...;)

If it's the bolt that connects the torque arm to the final drive unit, I think it's just held in with threadlock. There's another thread talking about the risks of using this bolt to mount a hugger - cheap Chinese bolts vs "quality" Puig bolt, possibility of it working loose, etc.

(I fitted a Puig hugger, threadlock on the bolt, torqued up correctly, and marked the bolt with permanent marker so I can easily check if it has moved. No obvious reason to me why a replacement bolt, 15mm longer than original, should be more susceptible to loosening. If it is this bolt that failed, was it the original?)

Still can't believe the explanation given by the dealer - "you used rain mode when the road was dry" - is genuine.
 
Still dont understand if the torque arm bolt came out then the splines would compress not extend? I cant understand why the splines would "fail" because the UJs would be the weakest points which I would expect to fail first.

All conjecture until you know the failure cause and the damage it has created - if the drive shaft has been spinning freely inside the swing arm then depending on the speed when the failure happened there could be consequential damage - if it was slow speed when failure happened then probably not much more than a few scuffs on the inside of swingarm.

if however the splines are stripped as you insinuate then the whole final drive needs to be stripped and the shaft withdrawn so a dealer wouldnt be doing this job they would either send it to a specialist or use a full pre assembled final drive via parts department.

weird failure - but at those miles I would say its nothing to do with splines more to do with either a manufacturing defect.

I share your questioning of this case.

Header says shaft failure.Yet, the description says that the bolt for the paralever brace came loose.
While riding, there is a lot of tension on this bolt. The bolt is further locked by Locktite. And even in the unlikely event that the bolt should become unscrewed the heavy tension on it would lock it in position. And the weight of the bike would still push on the link-arm and keep it in position. Further, I question that the splines or driveshaft would be ruined, as surely, if the bolt popped out, the rider would notice and stop.

Now, I am aware of the fact that the only thing that exceeds the imagination is the reality.

Time for some pictures....
