Put a Britten type "Cafe Racer" tank/fairing combination on it.The high tailpipes closer together and a real 2 up seat and I could see a very tasty retro-modern R1200S...That design is any bit as nice as italian designs lately and let me hope that there is something worth getting exciting about in the pipeline...!
The F800R is very nice looking too especially considering that they already had all the pieces in the storage bin...

Swingarm,light,pipe from the F800GS.Too bad about the chain...
