This is the maintenance schedule with associated service intervals for the Kawasaki Ninja 250R EX250-F, also known as the Kawasaki EX250 in different markets, or the ZZR250. It was made from 1988 until 2007 basically unchanged until Kawasaki replaced it with the 2008 Kawasaki Ninja 250R, improving the aesthetics and also a bunch of riding components like brakes, suspension, lights, and so on.
The Kawasaki Ninja 250R was originally introduced in 1986. It has always been the entry-level sportbike, with a riding posture that’s not totally upright (like a Bonneville or equivalent), but also not totally bento ver the bars, like on a ZX-6R. It’s a commuter that’s agile, or a casual sportbike that will sip fuel and let you go down to the shops.
The Ninja 250R is special in that unlike nearly any larger motorcycle, you can redline it in every gear (well, until you run out of power). You can really thrash it and enjoy it to the full, flinging it around corners with aplomb. So the Ninja 250R is a great beginner bike because it’s so forgiving.

General information about the Kawasaki Ninja 250R EX250-F
The Kawasaki Ninja 250R has a twin-cylinder 248cc engine that makes modest power, making it ideal for entry-level riders everywhere — whether it’s legally mandated or just a “good idea to start with a 250”.
Its compact parallel-twin design is lightweight and high revving, with a broad torque curve. It has decent mass centralization for easy handling by novices, with a rame that’s lightweight and rigid.
While not being a full-on sportbike like the ZX-6R from Kawasaki, the Ninja 250R has good cornering clearance and a low centre of gravity, making it fun to fling around back roads at high RPMs and lean angles.
The Ninja 250R’s engine is a high-revving, liquid-cooled, parallel twin engine with dual overhead cams and four valves per cylinder.
Its 13,000 rpm redline and six-speed transmission means that even experienced riders can get a lot of joy out of the little Ninja. Keeping the revs soaring is rewarding, with a jet turbine-like sound that is hard to eke out of a larger motorcycle on public roads (within the speed limit, anyway).
And on top of all that, the Ninja’s 250cc engine has excellent fuel economy even in this early carburettor configuration. Don’t be surprised if you easily clear 70 mpg (US gallons), even while riding it aggressively.
Like its larger siblings from Kawasaki, the Ninja 250R has an aerodynamic full fairing, Kawasaki’s progressive rear suspension and high-performance disc brakes.
It also has a low seat height for added confidence when stopped. Other features include an easy-to-read instrument panel, positive neutral finder, centerstand, and pop-up bungee hooks.
