Kawasaki ninja 250SL is very and stylish bike.The fuel economy claimed is 25kms per litre, I have ridden about 102kms and am down by 2 ticks in the fule gauge( there are 6 in all before the last one start blinking ) extrapolating I may get around 24 kmpl which is pretty decent.
For the first 800kms it is advised that you don't get to go beyond 3999rpm which translates to around 54 kmphr. I bought it on 5 march 2015.It is the best model of kawasaki ninja.I suggest all of you to buy this bike. Ninja 250SL drive is soft and smooth.
