Ninja 250sl a bike from Kawasaki is a powerful bike and having a aero dynamic design. By an aero dynamic design it takes not more time to reach 100kmph. But kawasaki ninja 250sl having some disadvantages by which it can get low rating it is just because of its body material. This bike part is mostly made up of fiber and this is a most big disadvantages for this, but in other way we can say that it having comfort and having good or better mileage which is good at this cc. so I regard you to that if u was interested in racing then only u can take this otherwise I suggest you that you have another choice of bajaj 200ns or apache 200rtr 4v.
