Description
Additional photos of this RK replica are available here for your perusal.
In the long line of Gixxers, the ’89 “RK” model (also known as the “RR”) is considered by some to be the most special of them all. Unfortunately, it’s also very rare – just 500 were built for homologation purposes, none of which were officially sold in the US.
In lieu of sourcing one, this seller built an interesting replica/tribute from a GSX-R750 that he stuffed a GSX-R1100 motor into – some of you may be familiar with that as a “7/11”.
We’ll leave the description of this highly-customized motorcycle to the builder/seller:
“This is pure badass! My desire to own an extremely rare 1989 GSXR750RRK led me to the point where I just built my own. But being that I can never leave well enough alone, I built this awesome monster retro GSXR7/11RRK. I started out with a 1989 GSX-R750 frame that I braced to Yoshimura superbike spec, then powdercoated a brilliant gloss black.
I added a 1994 GSX-R1100 braced swingarm with a Fox adjustable height linkage and Fox twin clicker remote shock.
The front end was treated to a fully adjustable set of Attack Performance triple clamps holding a set of 2012 GSX-R1000 Big Piston Showa forks with 30 mm K-Tech cartridges. Brakes are monoblock radial calipers from a 2007 Yamaha R1 clamping on Galfer 320mm superbike rotors with custom Core stainless brake lines all powered by a Brembo radial master cylinder.
The rear brake is a Brembo mounted to a custom underslung brake stay.
The wheels are lightweight GALE SPEED 10 spoke 3.5/17 front and 6.25/17 rear.
Gearing is all Vortex and RK 520 size.
The dash is a Honda CBR1000RR unit that displays all information resto-mod style.
In the motor department, I shoehorned a 1,127cc GSX-R motor into the 750 frame – it’s equipped with Yoshimura cams, Yoshimura head gasket, ported head, and undercut transmission.
The fuel comes in through a set of 39mm Keihin flat-slide carbs and exhaust gases fly out through a custom Vance & Hines/Yoshimura exhaust.
The oil-cooled superbike motor is cooled down with a 10 row Earl’s oil cooler with stainless steel lines and aircraft fittings.
I changed the stock cable clutch to a hydraulic Brembo radial assembly one for easy clutch feel.
The motor just pulls forever! I have not dyno’d this one yet but seat of pants is saying high 160s at the rear wheel. Of course this is all wrapped up in a Lance Johnson Paint Worx body work/paint job that is absolutely stunning.
This bike is a prime example of the present day and the past in a title fight. It’s a blast to ride and nobody ever really knows what it is. By the way, notice the short wheel base…can you say 4th gear WHEELIES? Party on! You can ride this bike everyday and enjoy that old-school carbureted grunt in a modern chassis set up. Wicked fun and beautiful. Just add fuel and smile!”
When we were sent the bike here at Iconic, it did not have any lights. We just added a “rain light” in the back for semi-legality so we could take it out for a spin or two, but please be aware that it currently does not have a brake light, turn signals, or mirrors. Our White Glove service would be glad to add a pressure sending unit to get you a brake light off the LED strip in the rear at no charge if the winner desires.
Adam has ridden this to the Rock Store a couple of times and says that it is a “truly great feeling old-school bike with an excellent throttle, wonderful sound and lots of pull. The brakes are suspension are most certainly dialed in and do a great job of keeping her planted.” Have any questions? Let us know in the comments and we’ll do our best to answer them!
