2006 R1200RT Non ESA Shock

[Roy in SC]

Greetings all.  I am having an issue with my Rear ESA Shock.  The shock works on the bench, but not on the bike.  After contacting Ted Porter to discuss options, he suggested installing an aftermarket rear shock or trying to find a low mileage OEM rear shock.  I have been searching for the Model Number of the OEM Shock, which I believe is made by Showa.  But I cannot find anything other than a part number.  The Showa model numbers are similar to the following.  Top line of numbers - 7  675  104  Bottom line of numbers and text-  B0482.

Can anyone provide me with the proper number and manufacturer for a 2006 BMW R1200RT?  Thanks

Doubt you find a cross reference number to a showa shock.  They usually have contracts preventing them from selling direct to the consumer to protect the BMW parts revenue stream.

Afternoon Roy

 

Your 2006 K-26 1200RT is right near the changeover where BMW increased the rear strut operational current. 

 

There was a BMW service bulletin on that era 1200RT rear strut operation.  Beginning with the 24th integration level (K024-06-08-500)  the ZFE was coded with a higher current value to better operate the rear strut spring seat. 

 

Does your rear strut have 3 wires running to the black connector?  If so then you might see if your BMW dealer can check to see if the (24th I-level) is in fact programmed in, if not then programming that in might give your rear strut enough extra current to operate correctly.

 

If your motorcycle is still on the pre- the 24th I-level programming then even a new replacement shock might not work correctly.

 

You can also try lubricating the movable upper spring seat on your shock as sometimes that will allow them to start working OK again with the early lower-power programming. 

 

Another options is IF you rear strut will operate on the bench (or on the motorcycle with a direct 12v jump) then you can add a battery-direct,  fused, center-off, 2 position spring loaded control switch to manually set your rear ride height using that switch. 

 

If you intend to go with a non-ESA rear strut then my limited info shows the  Showa 7675104   B0482 will work as it was used on the 2006 (2005-2007)  era non-lowered BMW 1200RT. I don't have solid info but it looks like the  Showa 7675104   B0482 will fit & work on all the hexhead (2005-2009 non-ESA, non lowered, 1200RT's. (at least I don't have anything saying, or showing, that it won't work)

 

There were differences in the 1200 hexhead RT early vs later ESA rear struts due to ZFE control changes but the non ESA shocks are manually controlled so the (ZFE) ESA control changes aren't a concern.

Thanks for the feedback DR.  I will look up the manufacturing date and follow up on the integration level.

If you need a non ESA shock, I have two that were removed from working Police models. They have different numbers on them. Don't know the difference. $75
