I say leave the gearing alone. Dropping the front just kills your top end on the straights, and most good tracks have a spot where you can use most if not all of the top speed.

I am yet to ride a motorcycle race track (in Europe) where cbr600f hits the top end and can use it effectively for a period of time with sprocket 15.Without sprocket 15 as Tahoe SC said your Honda will be track bike only unless the track is as straight as a donkey’s hindleg and stays straight for miles. Anyway, it will only hurt your top speed by4-5 mph but it will get you there hell of a lot quicker - you can do the math yourself. Most straights are about 400 metres long with a technical low lean angle curve just before it and one just after it. Also at 140-150 mph breaking point will be at about 150-130 metres before the curve and that’s for the brave!
Therefore, unless you are on a wide open GP track (if you watched my video and that is a GP track where Wayne Rainey holds the record btw…) my cbr600f does not reach top end with 15 sprocket and I still have 1000rpm to go… and I am cracking the throttle wide open really early on whilst leaned over quite a bit…
But here is the racers rule, to set up bike optimally for a given track; just before the braking zone on a main straight (where you reach highest speed) you should just hit you limiter in top gear.
