So the axle nut didn't come off but it looks like the axle shaft seized?  Bearing go bad in the rear wheel?  I've never seen anything like what you are showing.  The rear rotor doesn't look scorched so I don't think it was a rock jamming the rear brake pedal.  I can't really tell, MG.  I've updated your subject line a bit to get some more views on this.

Man, that looks like some SERIOUS heat forward and below the right side of the end of the axle.  That's crazy weird.

bearings or did you run over something?  That wheel shouldn't be wobbling like that.  Do me a favor and send a note to Ugo on what's going on and he can provide the translation.

Valerio's saying that he e-mailed the most important Italian motorbike magazine, "Motociclismo", and that they assured him about having immediately informed Kawasaki about it.
He'll keep us posted about the evolution.

My personal comment is that even if it is out of warranty and the mileage is high, things like that should never happen!
If the bearings suddendly broke/cracked it's a very serious problem: bearings should just become worn out and create play but NEVER break!  :o

I'm curious to know the feedback from Kawasaki: if they're serious they should send an inspector.

Thanks Ugo, you've saved the day again.  So it has to do with bearings, then.  Time to check mine.  I've had good luck on this bike, unlike the C10, with the bearings.  I do check them every year at least and so far (knock on wood) no issues.

I'm not 100% sure it has to do with bearings, but I don't see what else it could be!
When braking you hear the "cling" sound that is probably due to an eccessive play because somethig "structural" broke: what else if not the bearings??

Anyway, I think that Kawasaki has now plenty of clips to examine before sending an ispector: let's wait for their reply... not for too long, eh?   ;)
If needed I will contact them to push things forward.

Good luck with that! At least you won't have to speak with Mark here in the US.

Is it possible it may be the impacts from the two accidents the bike was involved in, that caused this?

Yeah, contact centers are the same all over the world!  ;D

I just spoke to Valerio on the phone and he confirmed that is the bearing
I also was doubtful if the small accidents he had could have had a role in this or if the mechanic had removed and mounted badly the rear wheel, but he excluded it.
He also told me that Kawasaki has already asked for the frame number of the bike.
Let's see... things are moving on.

Looks like good old pressure washer damage to the bearing. The grease gets washed out and the bearing self destructs. MGvalerioi's bike always looked nice and clean!
Bearings are cheap and easy to change. He's lucky it did not cause an accident.

It looks to me like the right axle bearing fried (horrifically overheated) and lost some of the needle rollers inside it. The interesting thing about those videos is that the rear wheel jumps out of alignment on the second revolution of the wheel, not each revolution. That indicates to me that what is left of the bearing is still rotating (probably just the needle retainer now and <maybe> a needle or two) and causing the oscillation to be out of time with the rear wheel. It also looks like the hub side of the rear wheel is supporting the rear wheel and causing it to turn pretty steadily and straight until the side- force from the brake application pulls the wheel away from that axis of rotation. I am not sure if this message will translate into Italian gracefully but I do not know how to make it much simpler and keep the meaning intact. ??

That bike is going to need a bunch of parts, perhaps including parts or even an entire new drive hub depending on how hot it got in there. The right axle mount is clearly shot as it badly overheated when the actual failure (I think bearing failure) happened. No doubt a new axle will be needed.

The usual mode of failure for wheel bearings is that the seal fails to seal, then contaminates enter the bearing itself and finally the bearing fails (rather than wears out). My 2008 C-14 is in need of a new rear wheel seal right now as a matter of fact. The wheel bearing is still fine but it won't stay that way for long unless sealed from water and road dust. By the way, I have replaced the front wheel bearing seals twice already on this bike and it is coming up on needing a set of front seals again, probably next summer.

I am not much for yelling about safety or becoming overly concerned about reasonably normal noises, wear, etc. but that is WAY, WAY outside of the normal envelope and needs to be fixed before riding the bike. Not sure how this will translate either but what you have there is NOT a Mary Jane Tinklepants situation.

Best of luck getting it fixed, and also good luck getting the factory to repair it. Not sure what Kawasaki's stance is going to be about this but it will be interesting to hear how it goes.
