So before you judge me based on the title.... I'm going to be looking into a new bike soon but the 300 community will NOT lose a member! It will just trade one off. I have been talking with my wife for a while about it and finally got her on the bike in a nice safe environment and she absolutely loved it! She wants to continue to learn and ride and I think its wonderful. She wants to take the 300 from me and that allows me to get something slightly bigger! I don't believe in anything 600 or above because I enjoy rowing gears and I will never reach speeds they can attain. My main choices right now are the CBR500R and the Ninja 400. I like them both and am leaning towards the 400 because its technically "faster". I know Kiwi has some obvious first hand exp with the 400 and I would love your input! Anyone else who has any on the 2 bike would also be appreciated! This won't happen until around june of next year though so I have plenty of time to teach her and get her and I to a class of some sort as I still want to go as well as time to make my decision. Thanks for reading!!!
