Peak HP is reached at about 8500 rpm and max torque at about 7000-7200 rpm on stock GS500 engines.  I can run my fastest pace keeping it between 7k and 9k rpm even though it's redlined at 11k rpm.  Rev a little past the HP peak and shift dropping to the torque peak.  I haven't redlined a GS500 more than a few times in over 130k miles of spirited riding.  A good job of carb, intake, and exhaust modification will extend this usable power range to 10-11k rpm and add a few HP and reduce gas milage and increase oil consumption.  Oil consumption increases considerably past 40-50k miles and can be too excessive after that if continuously pushed beyond 9k rpm.

Here is summary of all the published test relults I've found on the GS500:

This is from a friends GS and is very typical of stock GS curves:

Speed in gears at 7-9k rpm:
