Seeing that you found this website, you either own or are interested in buying a Kawasaki Ninja 250R. Excellent choice. The Ninja 250 dominates the competition in it's class!
Since it began production in 1983, the Ninja 250 has not changed much. The only major changes were the early models' belt drive being converted to chain drive, and recent changes to the engine to increase mid range power from 3,000 rpm's.
You will find this bike to be significantly easier to ride than it's competition due to the Ninja 250's natural riding position being somewhere between standard and sport. It really makes for quite a nimble machine. It has also been known to beat it's larger predecessors through short windy roads due to it's agility.
