Update 7.28.2015: This bike is now available as a Featured Listing from it's new owner. The new owner Lee would like readers to know that he is willing to put together a shipping and insurance package for worldwide delivery at $32k USD. Links are now updated to point to the current listing. Be mindful that when this listing was first written, it was for sale by another owner and some of the editorial reflects that. Good luck to buyers and seller! -dc
Back in the last 1980's, WSB and even MotoGP bikes were required to be based on production bikes that were available to the public. This requirement was known as the homolgation rule and it required at least 50 street legal motorcycles had to be available to the public in order for the same bike to be used as the basis of a race machine. Perhaps the most famous of these homolgation bikes are the RC30 and OW01 but other efforts include the Harley Davidson VR1000 (of which only 50 were produced for public use) and the Suzuki GSX-R750RK.
The 1989 Suzuki GSX-R750RK (also known as the RR/repli-racer) was a true "straight-out-of-the-crate" racer that was technically street legal but could easily be converted for racetrack use. In a sign of its true homolgation nature, only 500 of the 1989 GSX-R750RK/RR were produced and they were only imported into countries where motorcycle racing had a significant following. As was typical for homolgation bikes, most were snapped up by deep pocketed privateer racers who took them onto the track so finding one in good/OEM condition is a rare occurrence.
For anyone not familiar with the RK/RR, the bike had a significant number of upgrades from the standard model
"The RR received a new 40mm Slingshot carburetor, a 4-into-1 exhaust pipe, a close ratio gearbox, new rear swingarm and sub frame, new aerodynamic fiber bodywork with large air intake duct, solo seating with race number box and a 19 liter aluminium fuel tank as standard equipment. The dry weight 411lbs and 120hp at the wheel rivals some modern sport bikes to this day.
The RK was designed to be a bike which could be tuned easier than its short-stroke predecessor. Racing teams which were already adept at tuning the long stroke engine and so were more familiar with this revived long stroke design, The newly redesigned engine reverted to the original long stroke (70 x 48.7mm) configuration. Crankcase, crankshaft connecting rods and clutch were among the critical areas receiving more attention necessary for the race duty."
This particular 1989 GSX-R750RK/RR is located in Australia and looks to be absolutely pristine. I suppose the condition isn't that surprising given that the seller lists mileage of only 1,990 miles and states that it has never been raced. All the pictures seem to show a bike that is in absolutely perfect condition, with a unblemished triple tree/fork top as well as an exhaust canister and engine area that look like they were just assembled in the factory.
While prices for bikes with a production run of only 500 units are hard to figure, the few previous ones we have had on RSBFS for sale have all gone for more than this and condition of those listings weren't nearly as good as this one. Also the price for this GSX-750RK one seems to be right in line with other top shelf homolgation efforts of the same era such as the RC30 and OW01.
Based on the pictures attached to the auction and the bikes condition, I would be willing to bet that the the current owner is a deep pocketed, long term collector who wants to cash out his investment. However I do think this one still has some room to appreciate in value; this is probably the best condition GSX-R750RK we have ever posted here on RSBFS and its unlikely we will see one in better shape than this one for quite a while. I can honestly say if I was in AUS right now or was confident I could arrange shipping and import to the USA, I would be giving this one serious attention.
