I just replaced mine with one down in the front and up one in the back. You lose the top end speed and get more torque I have 2002 GSXR 1000, It also made my wheels more smooth, make sure to replaces the chain when you do the sprockets.

Get a -1 for the front, +2 for the rear.

This info is for a GSXR1000. But its useful....

The GSXR1000 is the king of the hill. The new 05 Gixxer1000 is absolutely amazing. The 01-02 models put a 180HP motor into a 600 frame. The 2003 and 2004 GSXR1000 were so far ahead of the literbike game that it's just NOW that the other manufacturers are catching up. It's in a league of it's own. But one problem the GSXR1000 does have it the absolutely RETARDED first gear. Who needs to go 85MPH in first gear? Not I! But what this will do is increase acceleartion across the rev range! The #1 upgrade for your bike is the 520 conversion, nothing comes CLOSE to it dollar-for-dollar.
This fits all of the GSXR1000 from 2001 to 2005 and increases power response across the rev range. Dyno tests prove that you can reach peak torque and HP an average of .8 seconds faster than stock! Even if your bike is absolutely stock, your bike will go from 0-100MPH in 3.8 seconds. That's the time it takes to get to 11K RPM in second gear.
Stock Sprocket sizes are 17 tooth front 42 tooth rear which has a final drive ratio of 2.47 The optimum ratio is 16 tooth front 44 tooth rear which has a final drive ratio of 2.75. You can increase the rear to a 46 tooth but you will lose approximately 8 MPH at redline in 6th gear. YOU HAVE BEEN WARNED that this modification is not for amateurs. Understand that the bike will be termendously different off the line with these modifications. Not responsible for soiled underoos.
Extensive testing on the street, eddy current dyno and on the race track have proven that this is the optimum ratio for your bike, however you may choose any combination of front and rear sprockets for your application.

I'd go down 1 in the front on your 750. You may lose a couple of mph on top, but I doubt you'd miss it.

I definitely don't recommend a 520 set up for the street, especially on a powerful bike, unless you just like replacing chains often. You're not gaining any measurable power difference, and the weight savings is minimal.
