PMSL...

I've eaten dinners bigger than you!

Shouts louder can anybody test what/what grade metal ALL (not just eBay) these aftermarket dogbones are made from??

Else we are limited to the most basic of tests I can do meseln - like a ‘scratch test’ and magnetic test!!

It seems there might be quite a few of these bones snapping, if the eBay add is true to its word then it IS made of strong material … so until someone disproves that they are, lets look for other possibilities …

The first that comes to mind is that if the linkage bearing seizes then this will put undue stresses on the bones (and in a direction they are not designed to take that sort of punishment), potentially resulting in snappage … could this be more correlated/related to the snaps than material?? (excluding this home made one).

I really can't be arsed to test them. When I need a new set I'll buy from a reputable seller who gives me some kind of liability insurance comeback and TUV approval, As Sarah said. I've heard from 2 or three sources about ebay dogbones failing, and bearing in mind what happened to my Bandit I'm not taking a chance with them, no matter what the sellers description says.

I didn't like highsiding, it 'kin hurt and I don't want it happening again.

Well at least I am able to admit to my mistakes, if only to warn others of the dangers.

How do you know that ANY of the aftermarket dogbones are ‘strong’ enough?? Just coz something is more expensive doesn’t mean it is ‘better’ … I think someone in the know needs to test them all ...

As for buying from a reputable dealer … if I am dead, I don't care what liability insurance the place had!! I’d rather know what the material is BEFORE failure and then make an informed decision!! Just coz the supplier is reputable, doesn’t mean a product they sell isn’t {insert you own expletive}

We also need to establish the cause ... like I said, it could be something unrelated.

If someone can test them and we find they are made of monkey metal, then this needs to be published. We do not have enough data to establish if it is material or some other variable at the moment, I’d be wary of ANY aftermarket dogbone with the info we have at the mo!!

You could apply this to any part you buy for your bike, you normally only find out it's crap after it's failed. I think your idea of getting every single dogbone made tested for strength is pie in the sky - it just aint going to happen in UK. In Germany they have TUV testing for parts, if it doesn't pass it can't be fitted, simple. We should have the same here so you wouldn't be able to put dogbones sourced on ebay from knocked_up_in_my_shed999 onto your bike in that case.

I agree that not all expensive stuff is top quality - just look at the leathers market - but there is a safety standard in place with leathers to guide people to the right stuff if they want good quality.

We'll leave the testing up to you then

I'd rather buy dogbones from someone like Harris, JHS, BanditMania or another known and respected supplier than from a guy I've never heard of on eBay. Chances are you won't die if they do fail, and then at least you'd have someone to go back to and say "I bought these, they failed, my bike is wrecked and you're paying for the damage". People like Harris etc don't normally sell crap products that are liable to fail, they deal in high end stuff that has a good reputation. Try getting anything out of your ebay supplier if they break and see what he says.

Stock, eBay, bandit mania?? it is not like a massive undertaking I’d even donate my dogbones for the test! (I’d like to know if it were a destructive test first mind!! ).

As for comeback, not sure you would get much comeback from a failed part other than a replacement part … I can’t see them giving you a new bike/leg/back!!

Mine aren't as pretty as that. Just two lumps of flat steel with holes in them. Done 30k on them so far
