I retired at the end of January 2015, and in preparation, purchased a 1983 BMW R100RS motorcycle for my third rebuild/restoration project. I figured I ought to have a motorcycle project out in “Brook’s Garage” to help orient me to my new life-style.

The R100RS was an innovative motorcycle when BMW introduced it in 1977. I loved it when I first saw one, and it’s been on my list of candidate project bikes since I finished the restoration of my wife’s 1973 R75/5 on July 4, 2014.
It was a snowy day in January when I first went to look at the bike with a fellow Airhead who owns a 1984 R100RS. The Craig’s List photos showed it outside, but when I arrived it had been put in a garage. The owner said he bought it for his significant other, but she decided it was too much for her “first bike”, so it hadn’t been ridden and they decided to sell it.
It came with saddle bags, some spare parts, a BMW tank cover, a Clymer manual, some parts catalogs, various registration certifications, the original owner’s manual and the original tool kit and tool box with the rubber cover.
The bike had 83,382 miles and a BMW MOA sticker on the rear fender mud guard. I took that as a positive sign; at least one owner was vested enough in owning the bike to join one of the BMW motorcycle owners groups. I got the VIN number and did a search to see when it was built and found the date was February 9, 1983.
I mulled it over and a couple days later made an offer a bit below the listing price and arranged to pick up the bike on the following weekend. I enlisted the aid another ABC member and we used his pickup truck to get the bike to my work shop.
