Additional photos of this Suzuki GSX-R400 are available here for your perusal.
In 1990, Suzuki introduced an all-new GSX-R400 for the Japanese market with the code name GK76A. Fierce competition in the 400cc category amongst the Japanese manufactures was fueled by the restrictive riders licensing rules in Japan that favored smaller displacement bikes and the TT-F3 racing class that spurred continual development of the models from the big four Japanese builders.
The GSX-R 400 was originally launched in Japan in 1984 with the GK71 model, featuring a liquid-cooled inline four cylinder engine with DOHC, four valves per cylinder and close to 60 hp. Lighter than its rivals (under 350 lbs wet), the aluminum framed Suzuki became a hit with its excellent handling, more-than-adequate brakes, and a race-derived heritage. By the time the 1990 GK76 model was launched, the GSX-R 400 had been through several changes and the new double cradle aluminum frame that mimicked the larger 750 and 1100 models almost looked like a step back from the previous model’s (GK73) modern-looking twin spar frame.
With that said, the GK76A came with huge improvements in new inverted front forks, better brakes, 17″ wheels front and rear, a new 4-1 exhaust, all new styling and an engine producing 59 hp at 14,500 RPM.
This example is VIN: GK78A106963, Engine #: K709-105871. The seller acquired it here on Iconic Motorbike Auctions in November 2019 – the previous owner was Gary Mortensen of White Knuckle Motorsports.
The seller is letting it go as he’s narrowing the focus of his collection down to Ducatis. He will also be selling a Honda VFR400 NC30 with us soon. In preparation for the listing, the seller had us clean/sync the carbs with a rebuild kit and install a new battery. Angel did the work, he notes that the brakes are at 90%/95% front/rear. It is riding on Michelin Pilot Power 2CT tires with date codes of 1517 and 1717.
Currently located at our facility in Santa Monica, California (please make an appointment for an inspection), this Suzuki is offered on a clean Utah title. Have any GSX-R400 stories or questions about this listing? Let us know in the “Comments” tab!
