1983 BMW R100RS->RT Project Complete

I restarted the project on March 1, 2019 after acquiring this bike in January 2015. My 1977 R100RS rebuild project halted work on this bike as I wanted to complete the 1977 RS in time to attend the 40th anniversary rally hosted by Todd Trumbore. I finished assembling this bike on September 30, 2020, so the build took about 18 months to complete.

I did a 10 mile ride as part of the first engine start before completing the project. It’s now early October and I’ve ridden the bike 200 miles as I break it in. One of the first trips was to get coffee with some “scooter scum” friends of mine. It’s a public unveiling, if you will.

I like to name the bikes after Muppet characters based on the bike color. I mount a Muppet figure on the bike so there is someone to talk to on long trips. And, if they talk back, it’s time to stop for the day and take a rest. πŸ™‚

A little over a year ago, I sold my R1150RS that I put 110,000 miles on. It was named Cookie Monster. So I’m naming this bike Cookie Monster Too, and transferred the figure to the top of the master cylinder.

This document shows a number of before and after pictures of the bike and includes a list of those people and companies who helped provide advice, services and parts without which I could not have completed the project.

I shot a walk-around video of the finished project and review some of the highlights of the build.

Now, it’s time to put lots of miles on Cookie Monster. πŸ™‚

  1. Congratulations on completing your mint R100RS. I am sure you are looking at many miles of happy motoring with confidence that nothing in the bike lies outside of your expertise.
    Just have fun, smiles are more important than miles!

    • Thanks Kit. I’m looking forward to completing the break-in. And then there are the tweaks that naturally need to be done and the farkles.

      Stay well my friend.

      Best.
      Brook.

  2. Brook, keep in touch regarding the tweaks, “farkles” and many many safe miles keeping the rubbery side down at all times. I would miss your periodic updates that serve as subsequent reminders to show my R90 some attention… After 46 years and at least two owners she still hums right along.

    • Hi Danny,

      Indeed, I plan to start doing the “farklization” work and I’ll document how that goes. And, keep the R90 on the road for many more miles and smiles. πŸ™‚

      Best.
      Brook.
