I don't know what the fascination with the repsol scheme is. Makes you look try hard. People think they are cool on a repsol bike but the guys they are riding with just think 'who does this guy think he is, he looks like a twat'. True story
Both the ZX10R and CBR1000RR are great bikes, but the CBR is smoother, more balanced, and better mid-range in the corners in my opinion. I ride with guys who have the Kawi. I'd take the CBR every time.
