試駕車友忍250上賽道！小忍250一直是日本輕檔街跑的指標（因為過去十年日廠只有Kawasaki做250c.c. 輕檔街跑...）新款300c.c.街跑的來臨，顯得小忍250有些老舊。相對的，因為二手價格越來越便宜，改裝零件多，越來越多人買來玩賽道。Kawasaki Ninja 250 has been the pinnacle of lightweight sportbike. (well, nobody else was interested in making 250c.c. sportbike) Comparing to recently released 300c.c. bikes, 250 Ninja does look a bit outdated with its analog dashboard and carburetor. Nevertheless, it's becoming a favorite among track riders for its affordability and great support in aftermarket community.
