The Kawasaki Ninja 250R (codenamed EX250; previous generations had market-specific names) is a motorcycle in the Ninja sport bike series from the Japanese manufacturer Kawasaki originally introduced in 1986. As the marque's entry-level sport bike, the motorcycle has undergone few changes throughout its quarter-century lifetime, having received only three substantial redesigns. In some markets the Ninja 250R has been succeeded by the Ninja 300.
