I've owned airhead BMWs since 85, and RS's since 92. The Motorsport holds its value well, got 9K out of it. The dealer was asking 14K and it sold in two weeks. I do not know what he got. However, at my age, I found the riding position too hard on my wrist, and I really got tired of yelling in my helmet at people pulling out of me and trying to stop the RS with ancient brakes.

Even if I didn't ride it, just clean it pretty nice, drain all the fluids and look at it.
