The fuel economy claimed is 25kms per litre, I have ridden about 128kms and am down by 2 ticks in the fule gauge( there are 6 in all before the last one starts blinking) extrapolating I may get around 23 to 24 kmpl which is pretty decent. There is an optimal riding fuel indicator which stops appearing in case you are driving in the wrong gear. For the first 800kms it is advised that you dont get to go beyond 4000rpm which translates to around 54kmphr.
It comes with a six gear gearbox and as I said, gearshifting is not a problem at all. The engine sound is music to ears but is very controlled and is not loud.It is a bike which will attract quite some attention on road while you are driving. It is actually longer than its big brother 650cc Ninja. Beautiful, attractive and agressively designed bike.
