I dont have any advice on the R1 but I have driven the 06 CBR1000 and the 06 gixxer 1000. The gixxer 1000 has a little more power. The honda seems to have a dead spot at full throttle like its getting too much fuel. The Honda is a little more comfortable to me but I already own a Honda so that might have something to do with it. The guy who owns the gixxer rode the Honda and he said it made his wrists a little sore after about 45 minutes of riding. I for one would buy the Gixxer if I were to get a 06 bike.
