So what is the demographic targeted by a Sports Touring motorcycle? People that want to go fast but have stuff to carry? People that want to go fast, but comfortably? People that want to go fast in the twisties, but not on their hands? Anyone that doesn’t want a classic American Cruiser? This is who BMW targeted when they designed their sports touring bikes, and this 1985 K100RS (Reisesport) offered on eBay was a major change in the 60 years history of the maker.
The K series of bike left the traditions of BMW behind, and almost left their core fans. An in line 4 cylinders laid on its side compared to the opposed twin Boxer. Liquid cooled compared to air cooled. Fuel injection compared to twin carburetors. Shaft drive compared to shaft drive. Ok that last one not so much.

What you do get in the way of sport is 983cc of 10.2:1 CR giving you 90bhp that will push the 548 lb bike (plus what ever you can stuff in the bags) to a top speed of 136 mph. If you had waited for the 1989 model you would have gotten 2 more valves per cylinder and 10 more HP and 6 more mph. The sport is defined by the size of the fairing, on the RS, a small compact fairing that may remind you of the bikini fairing of the R90S. Stepping up in Touring and away from Sport you would get the RT and then the pinnacle of luxury, the LT.
If you are someone that wants to be comfortable on your classic, and want modern (for the 1980’s) stylings, the K100RS might be the bike for you. But be prepared to possibly get a cold shoulder (air cooled?) from other Real BMW riders.
