130km of highway riding or city riding?
both are suitable for you. let me try to explain the difference between these two bike.
Ninja are using inline 2 engine, a very lazy engine in low rev, you are going to work a bit harder in traffic, but have the top speed advantage if you get a clear highway (how often do you find that in KL..)
CBR are using a single cylinder engine, engine response in very quick. better for traffic, not as powerful in top RPM, but how often do we do that on everyday basis?
CBR are the lighter and nimbler bike for traffic
maintenance, the CBR use less amount of engine oil, so CBR win.
well, i`ll be damned, the CBR win hands down. 250`ers not going to like this..
anyway, my suggestion is test drive both first..
