WTB Luftmeister vibration damper donuts

[Armen]

Glad it worked for you. I worked at a BMW dealer when the R65s were new. More than a few people traded R65s in or sold them because the vibration was so intolerable.
Used the donuts for 10s of thousands of miles on the R65, and now over 10K on my R100.

Thanks for starting this thread.I just finished making a home made version of the idea and installed in my bike.I have to admit these things work and the vibration is about 70% gone.No vibration in the handlebars or foot pegs. At 60 Km it is super smooth.
I sandwiched about an inch dia hard rubber bushing between two cup washers that I had lying around and the whole job took me less than half an hour to finish.It is worth it. Try this if you are looking for that super smooth ride.  

I'm intrigued.  Did you just cut up some conventional engine mount material in the size and shape of the existing 5mm washers?  And would the cup washer really be necessary?  I'm not finding much (other than the flimsy things used for wood screws) on the internet, and so I wonder if some large conventional washers would do the trick instead.

I Have been following this thread with interest. I have not yet been successful in sourcing the David Brown cone ring couplings in Canada. One question I have relates to the installation .Do you sandwich the couplings between 2 cupped washers before slipping them into place into place.

My set of dampers came with flat washers, and yes you sandwic h the rubber ring between 2 washers.

Thanks for the prompt response, now I just have to find a source .

I have found a possible supplier for the David Brown cone ring donuts in Canada , however they need to know the specific cone ring couplings that the donuts part numbers posted here apply to.

    Any help would be much appreciated.   Best Regards John Muir

I don't have any info here in New Zealand, my piece of paper is back in Australia and I wont be home till Christmas, just give them the part numbers below. Surely that should be enough info.
The donuts are available in rubber part number 0860 1906 or urethane part number 0037 6006.

OK I googled the catalogue

Seems the're off a David Brown Cone Ring Couplings-TaperLock-MCT. Part number MCT042-12. Which uses the GC1/4 cone rings that you need, part numbers as above. A full set for the above coupling has 24 donuts, so only order the 2 you need and maybe a few spares, they will last at least 5 years I guess.

Cheers Bruce

Thank You Bruce. I will forward that information to my supplier and see what comes of it. Best Regards John Muir

Sorry Ivan, it took me a while to reply to your post, got busy with some midterms.
Here are a couple of pics of the spacers I made for my bike.  They are working good for me.  I used tie end rod rubber cut in half and sandwiched between two cup washers (any solid rubber should do).  I glued the washers to the rubber for the ease of installation.
 All the stuff can be acquired from some parts retail or Ebay. The overall thickness including washers is about 1cm.  After tightening up in the frame the rubber gets squished between the washers and it goes to about the same size as regional spacers.  Hope it helps.
