Description
Click here for an VINData Motorcycle History Report on this 1991 Suzuki GSX-R400.
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-R400 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-R400 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 but 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: GK76A103863. The seller purchased the bike four years ago through an Iconic auction and states, “Sometimes you got to face your failures, learn a lesson and move on. I bought the bike thinking it would be the perfect beginner bike to get my son to ride with me. Limited in power and low seat height (we’re both 5’7″), but with a sweet motor and what was once state-of-the-art chassis technology. I refreshed it and enjoyed the process (and the result), but my son developed other hobbies, and the bike remains unused.”
The odometer shows 12,947 kilometers (8,044 miles).
Maintenance:
Per the seller, “All the normal routine elements (engine oil and filter, air filter, coolant, brake fluid, brake pads etc.) Cleaned the carbs. Refreshed suspension – fork oil change and replaced shock with a new, fully adjustable unit (from a 2006 GSXR-600). This made a huge difference in ride quality. The refresh work validated some of the assumptions (awesome motor, unintimidating power but still tons of fun, great basic chassis), while revealing some flaws (suspension, which was transformed as part of the refresh, and brakes, which could probably use a better master cylinder). The result was a bike that was one of my first choices for a fun ride up the mountains. Given that the other options in the garage include multiple Ducatis (916, Panigale V4, and even a Desmo) and Yamahas (R6 and T7), it says quite a lot. All that said, the original goal wasn’t achieved. My son, while he liked the image of a rider, never really got into riding. A shame, I know, but it’s clearly a fault of mine, not the bike!”
