I'm not a racer but do like the more aggressive posture from clip-on type bars and rearsets. I plan to do this mod when time and funds allow. Kevin used '93 GSXR 600 rearsets ('92-'95 same, '96 newer do not work). 

They don't quite fit, but a little work with the Dremel and they mount on the GS quite nicely. They require slotting the mounting holes, and using normal socket head cap screws to mount them. You could also grind away the raised portion of the mounting area to reuse the stock GS bolts.  See photos to understand

re-mount the master cylinder down lower, and straight. A small angle is not at all critical though.  The rear master cylinder mounts on the brake side by rotating the banjo bolt.  

All the shift linkage parts come with the rear-sets, and the only thing you have to do is make a longer shifter rod.  Extended a stock GSXR shift rod by welding in a section. 244 mm. for a race shift pattern (1 up, 5 down), or 222 mm. for a normal street shift pattern.

They are nice aluminum cast parts, and are much lighter than stock. They are 4 lbs. lighter overall, combined left and right side; the brake side alone is about 600 grams, vs. 1600 for the stock parts. That's 2.2 lbs. lighter!

The pegs are about 1 1/4" higher, and 1" further back. There is tons of cornering clearance.
