I have always liked the original R1; just something so right about that bike. The 1098 has never managed to attract me; looks too much like a modern variation on the 916 (which is design perfection in my eyes). Same with the BMW; fantastic bike, but I just can't get over its looks (she might be great in bed, but I need to be turned on, first.hehe).
I remember following a BMW GS once, on the Kwak, thinking I'll easily take him through the twisties. How wrong was I! I was surprised by how well those things can take bends.
