Suzuki ST250
2004—2018

I have tried to tell the model history of the Suzuki ST 250 on this page as I know it. 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.

2004 Suzuki year code: K4

The Japanese customers are offered some retro design Suzukis that are not available in Europe. One of them is the ST 250, first shown on Tokyo Motor Show in 2003. It has a 250cc single cylinder four-stroke engine with two valves per cylinder, traditional suspension and tubular steel frame. A direct plating processing to the aluminum cylinder inner wall called SCEM (Suzuki Composite Electrochemical Material) is used for light weight and heat resistance. Otherwise it's a traditional motorcycle with classic looks, no more or less. There's a big market for bikes like the ST250 in Asia, while the customers here in Europe don't even get a change to see those simple bikes with cool design. There is also a model version called ST250 E type with two-tone fuel tank, polished engine, chromed exhaust pipe, CDI ignition and an extra kick starter. In my opinion, both models look really good. I wouldn't mind having one for commuting or riding shorter trips with. Released in Japan in December 2003. Colors available: Pearl White, Solid Black (ST250) Solid Black/White, Pearl Dark Space Blue/White (ST250 E type) A few months later, the 28th of April, two more Limited Color versions of the ST250E were released by Suzuki Japan: Sonic Silver Metallic/Based Blue Metallic and Cashew Beige.
