Re BMW / Showa

BMW like other manufacturers run zero defect contracts with suppliers, this was well covered over at the Hubb forum some time ago. If the problems were as a result of Showa design / manufacturing then you could rest assured there would be a recall as it would be to Showa's cost not BMW.

As for forks being "off the shelf" fork lowers in particular are machine specific & not a standard item.
Axle & caliper mountings are a good part of the reasons for this.

The general conclusion is that the forks are a BMW design manufactured by Showa to order.

Re parts

A check and cross reference reveals there are now 3 part No's for each of the complete fork legs.
A new Part No will appear for the black 2011 fork lowers at some point.

All fork legs & lowers are interchangeable over the entire production period of F & G Models 1999 to 2010. The fact they are interchangeable indicates the mountings etc are all common & the Part No change is for some other reason, possible a casting change.

The axles, LHS & RHS wheel spacers, Yokes & Fork Brace are also common to the entire F & G Series & the original parts are shown as superseded in the fiche
