The 08 Kawi is a good bike for beginners and those who want to buy it once and for all. I don't see anything wrong with a 2 cylinder 250. The bike also comes with an EFI and Kawi claims that it does 25km/liter and I have no reason to disagree with the Kawi people especially when my oldie FZR can give me around 18km/liter with no EFI on it.
The only thing is, that the bike is just too small in size unlike the old monstrous models so would be a proper bike for guys below 25. My opinion! :-)
