When I was making my decision, was stuck between the ZX10R and the R1.
But the CBR was considered also for a while. Personaly I hate the way it looks, everything about its asthetics looks pieced together at the last moment. The way the bottom fairing is just thrown on there, usualy in primer gray or black, screams dogshit to me. The exhaust never really looks right even if you take your time to make your aftermarket pipe sit correctly etc...
When I sat on the CBR I felt like I was sitting on top of it. When I sat on the R1, I felt more part of the bike. Im 5'11 170lbs if that helps with feeling dimensions.
The CBR just has way too much I'd need to do to it to make me like it, which is why I got the R1.
To me the R1 is only surpased by the italian beauties. It looks gorgeous and goes like stink.
And no Im not a poser, but like with my cars, I like to look at it and enjoy it too, not just have a fast but shitty looking bike.
Get whichever YOU like better though, go sit on em, try finding friends who have them, but it will be difficult/impossible to get a test ride on either. Performance wise both will be very close.
