1975 R75/6 Install Sienbenrock 1000cc Upgrade Kit

This bike is my first BMW that I bought new in 1975. It’s the first bike I rebuilt. After I put over 100,000 miles on it, I gave it to my son, Branden. In about six years he added another 100,000+ miles on it. So it’s time for a top-end refresh. He decided to install a Siebenrock 1000cc upgrade kit that we got from Euro MotoElectrics.

Here is video of how Branden did the work.

1983 BMW R80ST Project Complete

I started this restoration in December 2021 and completed it in early July 2023. There were some periods when I was otherwise occupied and wasn’t able to work on this project. I estimate it took about 16-18 months of work to complete this restoration.

My goal is to auction the bike and donate all the proceeds to the Motorcycle Relief Project.

Here is a link to pictures of the completed rebuild of this 1983 R80ST.

This is a walk-around video I made prior to starting the rebuild,

1983 BMW R80ST Install Side Covers & Muffler Heat Shield

When I got this bike I found the left side cover, but not the right. Bud Provin of The Nickwackett Garage offered to supply me a new right side cover at no cost in support of my project goal to auction this bike and donate all the proceeds to the Motorcycle Relief Project.

I wasn’t able to get an ST muffler, so I installed an R80 G/S muffler from Keihan Systems in the UK. They provide an adapter kit to mount the ST heat shield on the G/S muffler.

I also had to repair the original left side cover tabs as several were broken.

Here is the link to the documentation and the summary video of how I did this work.
