Not many people drag race a 600cc sport bike, they are more suited to road courses. Never the less, expect a bone stock R6 to give you a 1/4mi time of around 11sec flat....and I have seen modded ones go to mid 10's. A bone stock R1 will be a mid to low 10sec ride with the sky the limit (8sec with nitrous of turbos).
Unlike cars though riding a sportbike is much harder to extract the best performance from. Don't kick yourself if you can only manage 12sec times on an R1 (I have seen modded GSXR1300's do 14sec because a squid was riding).
Getting a good launch while keeping the front end down is the hardest part, most people keep the engine at 8-9000 rpm's and simply ride the clutch for the best launch, but it is easy to loop like that.
