Was there ever a 'monster edition' CBR1000RR?

Must be some, who just put the stickers on.
"Monster" was sponsoring Kawasaki, when they were in the MotoGP, as far as I remember

Correct, the Monster editions are on the '09 Kawi's. There were several variants available, the 6r,10R and 14 I know for sure. Then I believe there were a few in the MX series and possibly others.
The 6 and 10 were gorgeous and they had a great feel to them. They just did not balance under me sitting still as easily as my 929 does and they riding postion is of course lower. It was a much better feeling bike compared to the Suzukis and Yamahas. I never rode any of them, that was my evaluation in the dealer showroom.

As above.

Know a guy with a monster zx10r.

Just stickers...
