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.

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,

This shows the way I put the R80ST back together after disassembling it down to the frame.
Here is how I disassembled the bike.
And this provides an index of all the work I did to restore this bike organized by the parts main sub-categories.

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.

Folks,
Daren Dortin posted a podcast on his Type 247 podcast site about this project today. You can listen to it on either of these links. You can hear more about the charity, Motorcycle Relief Project, that I am going to contribute the proceeds of the auction of this bike to.
