Additional photos of this GSX-R750RK are available here for your perusal.
Suzuki lengthened the stroke of the motor to make it easier for race teams to tune, and there were extra goodies like a magnesium cylinder head cover, Mikuni BST-40 carb, close-ratio gearbox, stronger clutch with an additional plate, aluminum fuel tank, quick disconnect fiberglass bodywork, wider wheels, lower handlebars, repositioned footpegs, thinner seat, 43mm front fork with rebound and compression adjustment, and 310mm front disc brakes.

Because of the race prep, some bolts had been drilled for safety wire and an underseat oil cooler was installed (the only place it could be located because of the full Yoshimura exhaust). Unfortunately, the race team sponsor pulled out, so the racing aspirations disappeared. The bike sat unused until 2004, when the owner’s son decided to use it for road use and registered it in 2004. The drilled bolts were replaced with new ones and the underseat oil cooler was removed at that time, so there’s a section cut out of the under tray plastic. You can only see this if the seat is off or if you’re under the motorcycle.
This RK has never been raced or crashed. The bodywork was only repainted because it had the typical blistering problem that some of the RK/RR’s experienced – similar to the issue on Honda RC30’s where they used a bad primer and it blisters over a period of time. Special care was taken to match the OEM colors.
