Suzuki GS300L
1982—1984

I have tried to tell the Suzuki GS 300 L model history on this page as I know it. The page is still under contruction. I would be grateful of any contributions — sales brochures, magazine ads, magazine articles, pictures, specs, facts, corrections etc. Please scan the material in JPEG format (large enough that all the details are visible) and send them to me. Please tell me the source and the publication date if possible. If you send me pictures of your own bike, please follow these instructions.

Suzuki presented its lightweight cruiser GS300L in 1982. It looked like its larger sisters and had everything that appeared necessary for a genuine chopper: high bars, a broad step-seat, sissy bar, 16-inch rear wheel and lots of chrome. The small two-cylinder engine had an ultramodern TSSC cylinder head (twin Squirl Combustion Chamber) with 4 valves per cylinders, a balance shaft to reduce vibrations, a pointless ignition and naturally an electric starter. If the model had ever been available for the European market, the model would have been sold as GSX300L. It would have probably received a disc brake for the front wheel. The U.S. biker had to get along with drum brakes, which in view of the maximum power of approximately 30 bhp today appears a bit adventurous. The GS300L was not made for serious touring but for cruising and having fun with and for that it was quite good a bike. And it looked good. It came in two colors, black and red metallic. The model was initially equipped with Suzuki five-star light alloy wheels but apparently was later available with spoked (wire) wheels. Unfortunately I haven't got any official pictures of the later model years. The small cruiser was somewhat a success in USA. The model was built with only smaller changes until 1984.
