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. I have also heard
(May 2004) that another version, a dealer customized edition of
the ST250E will be released soon.
