8- 2011 Kawasaki Ninja 400R: The medium-displacement segment gets more crowded by the day, with the latest member coming from Kawasaki. At $7,499, the Ninja 400R happily fills the void between 250cc and 600cc models. It replaces the obsolete Ninja 500R, much to the delight of new riders. Versatile, easy to handle and just powerful enough to extend the fun over many seasons, this sport bike offers the same chassis and riding benefits as the 650R for less money.
