A gen2 needs 18/41 gearing to do 200mph, or a 55 series tire. That's assuming you have enough motor to pull your body weight to that speed too. It will also be alot easier to do when not limited to one mile from a dead stop.
I've yet to do it myself.
Got-Busa is a good one to ask these questions to as well.
Gen2 stock gives up at around 196/197mph, derestricted. Otherwise it's 186mph
Gen1 99 and 00 models are good for 193/194mph, as they were not restricted.
02 to 07 are limited to 186mph, and derestricted are capable of the 193/194mph.
These are also what the bike is capable of, not what it will do.
Rider ability, rider weight, temp, humidity, wind, elavation, road, areodynamics(mirrors will slow you down!) ect., all come into play.
200mph is no easy task, despite what the guy on his 600 tells everyone.
