Re: BMW U-joint spiders

 



This isn't quite right. The system is that aftermarket parts have to
be approved by the inspectorate, TUV. Their testing is very stringent
and expensive, and for small accessory companies, it isn't worth the
hassle or expense.

But if you gain TUV approval, that tells the rest of Europe that
you've cracked the big one, and your stuff is good.

 



Actually, there are some "sheddies" in Germany making some
really nice aftermarket high tech stuff for the bike, but you're
correct that they're working outside the established supply chain.

If you're in the orthodox chain, the idea of somebody marketing a
wierd top gear with one less tooth that mates with a stock gear by
using
bizarre gear tooth curves is probably horrifying beyond belief.

Cranking out strange and horrifying aftermarket parts from an backyard
machine shop may be a sort of Gemanic equivalent of sticking it to
the man.

Here is one that I have actually bought raceing parts from.

Never dealt with motoren-israel though I've heard
of them. I have bought from Siebenrock and Motobins.
Lots of good stuff out there on the internet. With
Siebenrock, the computer translated correspondence
back and forth was pretty entertaining.
