2004 Kawasaki ninja 250r is the next edition of old 2003 edition, guys.. what should I do before buying a used motorcycles? looking for specs and also performance and of course the style and design. Truly, the 2004 Kawasaki ninja 250r design and style (this bike also named Kawasaki EX 250R) is not lot different with old series such as 2003 Kawasaki ninja 250r, even the engine and performance.
