I would definitely recommend the 250 over the 650r (guessing the 650 is the kaw) Not just based on your deminsions, however with your size you may be more comfortable on the 250, but also because this new ninja 250 has considerably more power than the previous years and looks SO much better. The resale values on the Ninja's hold fairly strong so if you take care of it and want to move up, selling it won't be an issue at all.Originally Posted by budlite
