When my bought from new 2000 Africa Twin reached 130,000 miles I replaced it with another secondhand 2000 model with only 20,000 miles on it. The lower mileage bike was the same colour. I stripped all the bodywork and wheels off of the high mileager and stored them away as spares and sold the frame and engine to a man who collected it in the back of his estate car. That was in about 2006.
In 2010 the second Africa Twin had gotten up to 105,000 miles and the generator went. Replacement was expensive and the pattern parts had gained a reputation for being a bit ropey. The bike then sat there at the side of the garage until this spring when it was in the way of a reorganisation and a new bike ramp. I stuck a few pictures on one of the forums and someone bought it as a non runner with the spares from the first bike for £750. I had originally intended to give it way for free, so it was a bit of a result.
