I have ridden the Mission R and I can tell you it sure does not feel heavy. It is fast and turns wonderfully. While not the same as your S1000rr (458# wet I believe) not many bikes really are. (Big fan of that bike myself) The other part about that bike is if your riding on the street and don't care about trying to go 150mph drop the gearing down and from any speed the front end is a flick of the wrist from pointing to the north star (I did't try this since I didn't have the money to buy the bike if I dropped it).
