I'm looking at buying my first bike in the near future and I'm looking at the Kawasaki Ninja 250r and the Ninja 400r. I realize the 400r has more power and will be better on the highway will probably keep it longer than the 250r. My question is, is it worth spending 2000$ more for the convenience of fuel injection and not having to warm up the bike in the morning before riding? Also, is fuel injection on a bike like port fuel injection on a modern car or is it like older TBI (throttle body injection) on older cars. I know the Honda CBR250R is coming out in the next few weeks but i don't rely like a one cylinder because of the vibration.
