This 1981 BMW R100RS (VIN TEX205829) runs an EML sidecar, fitment of which apparently required all the donor bike’s components to be swapped over to an EML-made frame. It’s an odd but interesting rig, with a forward tilting clam shell side car top/door and some pretty out-there styling, but the seller says it runs great, adding that it’s ready to be ridden anywhere. Find it here on eBay in Mount Clemens, Michigan with reserve not met. Special thanks to BaT reader Matt for this submission.
More on the re-frame, this time in the seller’s own words: “The rig is titled as a 1998 Assembled Vehicle. For those of you that are not familiar with these sidecar setups, the EML rig is complete with the sidecar and the frame. The donor bike, in this case a 1981 R100RS, has all of the necessary components removed from the original frame and placed inside of the new EML frame. At that time, due to the new frame being used, the unit is re-titled.”
The ad goes on to note that the bike appears to have been repainted at some point, adding that finish is nice overall despite some roughness on the lower front fairing and a deep scratch on the sidecar, the latter of which is documented in additional photos visible within the listing. Also notable is some bubbling on the left side cover, visible in the photo below near its top left corner, just aft and below the tank. The fiberglass sidecar is finished inside simply with carpets and a vinyl covered seat, but build quality does appear to be quite good.
A Dutch company founded in the early 70s, EML is an acronym for “Eigen Makelij”, roughly translated as “self-made.” The seller notes that the bike had been sitting for sometime when acquired, and lists quite a bit of recommissioning work including rebuilt carbs, new fluids, filters, tires, fitment of replacement petcocks, plugs, a fresh batter, new fuel lines, voltage regulator and weatherstripping. Additionally, the bike’s electrical system has been completely gone through, and is now said to be fully functional with everything noted as working properly.
The ad further notes that the bike starts quickly and pulls well through all gears. It will smoke a bit when first started after sitting for a time, but this is fairly common for horizontally-opposed motor designs. Said to be ready to ride anywhere, you might as well bring a passenger.
