I'm 6'2", 180 lbs. I have some time on a CBR250 and Ninja 300. I liked the CBR250 better. The Ninja might make a few more HP, but the CBR actually makes a ft-lb or two more due to it being a longer stroke single vs a twin cylinder. It was easier to ride in traffic and modulate the clutch than the Ninja. I expect the next CBR300 to be even more betterer. I have ridden a CB500X and a NC700X, and ended up buying the NC700X. It is my daily commuter, averaged 63 mpg, and is the most comfortable bike I've ever ridden.
