Honestly, I don't actually hate the converter that much. What I do dislike is how the fairing is made up of like 3 different pieces. I would rather have a one piece like my Daytona 675 - much classier looking.
The S 1000 RR is almost identical to the zx6r, I just hope it isn't as flimsy.
Other than that one single concern - I really think the BMW S 1000 RR is a really sexy bike.
