Rear end issues - almost died!

I picked up my bike from BMW Toronto after they'd done some work including replacing the rear ABS sensor, chain and both sprockets. There was a squeaking noise coming from the rear when I picked it up but didn't think much of it.

This morning when riding on the highway the tail started to wobble violently (almost got thrown off) and the ABS lights came on. I pulled over at the nearest gas station and saw quite a bit of damage to the rear.
Finally got the bike to the dealer (thankfully it was close by) and dropped it off to be checked.

Looks like the rim and brake caliper are damaged. I'm hoping to get some opinions on what should be done and what may need to be replaced from you guys. What can I do with the dealer.. It was a shitty scary experience just because someone didn't do things right (I'm guessing the wheel wasn't mounted onto the swing arm properly).

It looks like they forgot a spacer. My guess is #9 is missing. Instead, there is some other washer/spacer by the looks of your second picture.

Forged wheel, rear. Fits: 2014 BMW HP4 | Cross Country Cycle

I would have the replace the wheel and brake caliper holder. Not sure if the axle is damaged. Time to call in our good buddy @bennymx

OP- Glad you are alright! That's some scary stuff right there. Looks like you'll be getting some new parts free of charge. Too bad it had to happen that way.

Is it possible to mix up the spacers from side to side? 9 and 19? The whole wheel has been forced to far toward the caliper side. Rubbing the brake rotor, the abs sensor ring and welding the spacer to the wheel.

How does something like this happen? Are there not step-by-step checklists provided by BMW for assembly and disassembly of components? Did they just "wing it"? Scary...

Thanks everyone for your replies. I'm gonna be getting an official assessment from the dealership this afternoon and will be asking for brand new parts. I wonder if the swing arm will need to be replaced too, not sure how bad..

The part that sucks the most is that the weather just got better and our very short riding season just started and I can't ride my bike.. I'll ask for a loaner bike.. and I want them to cover my service for the next 5yrs. Super pissed

Spoken like a true pilot. Most mechanics do not use a checklist.


You may appreciate this book.

Well, mine do...at least during regular mandated servicings. Probably not during things like tire changes...but I will pay close attention now when I have those things done.

Interesting you mention that book...I recently read "Being Mortal", by the same author. Depressing book, unless you enjoy thinking about dying...which I most certainly do not!
