2013 GSW 10 klm Blown Gearbox & Engine. Seized back wheel.

Just a quick note! It seems that the clutch basket nut came loose on my bike which then caused the problems. I am not sure what else was damaged as a result of this!

I did however came to an agreement that I do not want the bike back and will be taking delivery of another bike.

Wow! Same problem as mine. How old how many klm?

Still negotiating over here...
 
I know what you mean JB, two categories of assembly error or design fault each of which can be liable for a wholly unnecessary and extremely dangerous transmission lock-up and very little discussion. There are enough fundamental risks to riding motorcycles without manufacturers needlessly adding more.

If I was a gambling man I'd be putting money on a team of engineers at BMW currently looking at what other faults could cause cam chain failures and catastrophic transmission lock before the issues result in a death. What would the result be for BMW as a company if a group of riders hammering through alpine roads with lots of Go-Pros running when suddenly the back wheel of WC locks and spits the rider under an oncoming coach or truck? Massive internet coverage of the video. The number of failures have been small but any one could have been disastrous.

There is also most likely a team looking at design amendments to keep broken chains out of the transmission.
 
I got it May 2013, has 16500km on now!

I also purchased my new 13 GSW in May 2013 (Dec 2012 Build) and it now has 9726 klm on it.

I can see a recall or service bulletin coming out on this.

I think we are due an explanation from BMW as to how these nuts are working loose and what BMW are doing to ensure that other GSW models are not going to be affected.

Here are my VIN lookup model details, not sure if that helps or not:

I hope they take this seriously and act very quickly.

I, like Herman I am sure, am still a little freaked out that we could have died on this bike.
 
Surely there can't be a fundamental design flaw or inherent manufacturing problem ? I mean, BMW boasted of testing these new WC's over half a million miles, did they not ?
 
I would accept the repair - the bike has 10k miles on it after all. Do you really want a few quid off an upgrade to a new bike ? - you will still lose more money in the long term and was there anything else wrong with your existing bike/ were you unhappy with it ? (before this incident). You could ask them to chuck in some free servicing as compensation for the inconvenience - or push them to repair it quicker.
 
If the input shaft shaft to the transmission can move horizontally when the clutch hub nut is loose, that seems like a similar design issue to the countershaft problem on the DRZ400, in that there is no internal shoulder&clip holding it in place without the nut. Lucky for me I own both bikes, not!

Guess if my bike starts making weird clunky noises and vibrations, I will pull over with more alacrity than I might have done previously.

Engine kill button and "clutch in" in as few milliseconds as you can manage. If you're a believer start praying. If you're not don't worry as you'll appreciate that it won't make any differance anyway.

If the gearbox self destructs and locks up, what difference will pulling the clutch in make?:nenau
 
Guys, I have not yet seen the nut and how much thread is on the shaft. It may be that it loosens over a period causing play in the shaft and thus starting small amounts of damage versus completely letting go. Or when it loosens it does so instantly causing the damage we have seen here. Maybe check your oil for metal fragments?

I got a little warning that something was wrong a few minutes earlier. I heard like a slight clattering from the front of the bike, I was not quite sure what it was and I was not certain the sound was coming from my bike as I was in a tight formation of many bikes riding under the speed limit. I was also unable to pull over safely on the road I was travelling.

Just to be clear, my rear wheel did not seize completely until the bike had stopped and cooled down. I was still able to push the bike around albeit with some noise and resistance in the drivetrain. As I entered the driveway of the cafe to stop, the bike stalled a few times presumably as the clutch lever was having little effect and thus being in 1st at low speed with out a clutch stalled the engine.

I suspect if I had of kept riding that at some point it would have seized the back wheel or made a lot more drivetrain noise.

We GSW owners need some clarity on this. Apart from the safety aspects, 13 GSW models will be out of warranty soon, in Australia we only get 2 years. We also need to understand which year models are affected and what is the intended check/fix from BMW.
