Even over here, the Euro was never as commonplace as the ZAB and Customs
I see more GL's than Euros.
I'd guess turbos are the rarest followed by the Eurosport
next the GL's and Customs are kind of on a par and the good old
ZAB is still common as muck.
engine and mechanical items are often interchangeable with other bikes
and easier then say body panels which can be hard to source.
Eurovee has had loads of them and may be able to shed more light
What is it you need exactly?
you could try
theres also a place in germany that sells lots of
CX bits and may cover the Euro but cant recall the name
at the mo.
