Bent Alloy

[Slipperyeel]

Try to beat it back into shape or manipulate it back using hydraulic pressure without proper jigs and formers and it will most likely crack the wheel .
It is not a top quality item it is built as light as possible and as cheaply as possible in a factory in China to maximise BMW's profit margins.
Get a specialist to do it properly or replace it .
I've been to two companies in the past one of whom used to repair and straighten wheels for the Porsche Cup cars amongst others and the second who was trusted to straighten and repair police patrol car alloy rims and both of them had very professional looking jigs set up with interchangeable formers and they said that in some cases the repair could be done cold in others the rim had to be heated to stop cracking .
If it was mine I would speak to a professional and take their advice as a front wheel failure at speed is not a pleasant thought or just get a local tyre monkey to beat it nearly straight its your choice .

I agree with you on some points Neil, especially about the original quality of the wheel... which is precisely why heating would trouble me.

As for beating it into shape that would harden it even more. The only way is with a hydraulic press... and yes the 'good' side would need some support, but the dent would need localised pressure - in all cases you'd need something the to spread the immediate area of contact and protect the finish.

It's a gamble. It might crack. But because of the costs involved it would be daft not to try. I really wouldn't heat it though.

Thanks for all your input. I have spoken to Motoliner and I am about to package it off to them. As for a claim, it was an unstable stone wall on the edge of an A road. Surely they have some responsibility. I'm not trying to swindle them out of hundreds but if I can get some of my repair costs back that would be nice.

If the stone wall belongs to HRH you are in for a long battle, and not the HRH member here.

Farmer/Landowner or householder's responsibility for the wall(s) around their property......................not Highways

I was going to say JB, but thought HRH has a bit more land.............

Well done for getting onto it so quickly . As per Mike Rocks at the start, I'm sure it's fixable.

Feedback would be interesting ie. Did they heat it. I'm still surprised they would use heat. Is bad enough welding an alloy car wheel - which is a gamble and doesn't really work.

As you are implying, heating is an absolute no no. When aluminum temperature rises above 150 C, the internal structure starts to change, and one has no control of the condition of the wheel. Also, like copper, aluminum looses it hardening when warmed up, thus the repaired part will be softer and prone to more dents later on.


I have repaired my own rims 3 times, using my hydraulic press, and it has never posed a problem, nor did the repair damage the paint.

If OP sends the wheel to a professional shop they surely will know this..

We're on the same page. Adding to my concern would be the need for precise knowledge of the alloy...

As you say, I would Lee to think Motoliner are way ahead of us on all of this. And regarding the OPs damage, it looks straightforward, and doesn't appear to be so bad a dent.

Years and years back, I nearly sent my Katana 750 to Motoliner after i T-boned some idiot (who I'm sure was trying to kill me). But in the end after lots of checking, I decided the frame was actually ok. Send thinking back to the puny stantions they used to use back then, it's not really a wonder that they absorbed everything! I got another happy 18 months if that bike before I sold it.

UPDATE:
Wheel is back from MOTOLINER and looking good. In fact when I had the tyre put back on it didn't need any balance weights.
All up cost me around £125 including post to motoliner and tyre on/off/balance so happy with that.
They did use some gentle heat and I was warned that the BMW rims can tear during the straightening process and require welding but mine didn't.
Certainly recommend Motoliner to anyone with a similar problem.
Thanks for all the comments

Result . I can't imagine they used so much heat if the paint finish is undisturbed.

Well done for getting it all sorted so quickly.

They have an excellent reputation, and won't put money over safety.

Hopefully you never need them again.

IMO the worst advice you could give! Have it repaired by a specialized company. It will require heating the rim, so it may need repainting.

Actually it’s not the worst advice - I knew a man who repaired wheels for a living, more than 50 years in the game repairing and rebuilding car and bike wheels before he retired a couple years ago. And he used the method that Myke suggested.

Motoliner Kent , they have done two wheels for my riding chum .. great service .

sorry should have read above but hers a free link

for motoliner from me as well. I had my GS front wheel sorted by them after it started looking pretty similar to yours.
