i test road the cbr 600 good low down power not so good top end  also not happy with the amount of engine noise and very snatchy fuel injection that felt to me to be very harsh on gearbox and or chain . i felt it handled well but does'nt match the 954 any anything needless to say i ended up buying the 954 but in saying that if i was to do it again i would go for the Suzuki 04 on GSXR 1000 very fast bike thinking of selling and going to the GSXR after a test ride the other day they sort the men from the boy's thats for sure
