go with the Er6n (yes I know its over your budget, but in the long run, you'll be happy you took the 650.

extremely reasonably priced for a big motorbike in Malaysia compared to its "luxury" brethren.

I dont think you plan to ride 250+ kmph right?
This bike will cruise at 150 perfectly for hours. 17L full tank might take you around 300 km (but this one gotta confirm with the owners first)

The er6f to me is just not worth the extra 7k for the fairing.
If I wanted speed so badly I'll just save more for a CBR 600.


Going for the 250 R is fine if you feel you're a beginner and absolutely in no hurry when you makan angin. And doesnt lose out on looks either.
