Here are a few more parts pics.
The solo cover is just the outer shell, similar to what you get when you purchase an aftermarket carbon fiber cover. I reused the inner shell with my Tekarbon CF solo cover.
The BMW outer shell is in excellent condition and if you search the R1100/R1200S forum you will find a thread where someone describes how to fasten the shell to the bike. I do not believe that BMW sells the inner portion by itself.
