The Kawasaki Ninja 250R (also known as the EX250 in the U.S., and GPX250 elsewhere in the world) is a long standing model in Kawasaki’s lineup, introduced in 1986 and continuing in production until 2007. The 250R was marketed as an entry level sport motorcycle intended for normal use on paved roads. Compared to present industry designs, the 250R is more a “sporty-standard” motorcycle with a fairing than a true sportbike (considering its ergonomics, chassis design, and engine placement within the frame), but it is still an excellent sport machine.
