Have seen some posts here and there about the rarity of the R100CS. I just purchased a 1982 R100CS, S/N 6188165, and was wondering if anyone has any info to share? I was told a marine purchased this bike new while stationed in Germany and shipped it back after deployment, however it does have a US speedo. It also has a factory kickstart which I have heard was not available here. I also have the original paperwork from the purchase at Zweirad Herzog.
