Those who overlook or dismiss the Kawasaki Ninja 250 line of sport-bikes are seriously missing the point. The quarter-liter Ninjas are nimble, fun, gas-sipping motorcycles that make both city and byway riding a simple pleasure.

However, when you consider that the little Ninjas are powered by a single cylinder, 249cc engine, modest performance numbers are to be expected. The 250 Ninjas put out about 28 horsepower and around 17 foot-pounds of torque. Needless to say, a little more zip is a welcome addition to the diminutive Kawasaki.

To get the most out of that little rev-happy single, K&N has engineered a high-flow air filter to let the Ninja 250 breathe. The K&N KA-2414 direct replacement filter is specifically designed to increase horsepower and torque while, at the same time, offering a high level of engine protection.


The K&N KA-2414 air filter features the legendary cotton gauze filter media that has made K&N the industry leader in performance filtration technology. The high number of pleats in the KA-2414 provides an extremely large surface area to flow an increased volume of air.

That added airflow is a significant factor in getting the most performance out of the Ninja’s 249cc engine. Any engine tuner will tell you that more airflow boosts the potential for better throttle response and increased roll-on power. Those are performance byproducts that any Ninja 250 owner will appreciate.


Reliability and ease of ownership are two of the most appreciated attributes of the Kawasaki Ninja 250. To keep that engine running clean and trouble-free, multiple layers of K&N’s advanced, oil-impregnated filter media provide a premium dirt-catching line of defense.

K&N’s rigorous and highly-controlled filtration testing reveals very impressive estimated filtration statistics for the KA-2414. The testing shows that the filter provides a dirt-holding capacity of almost 29 grams. It also reveals an estimated overall filtration number of over 98% percent. That is protection you can count on.

Care and Installation

The Ninja 250 is known for economy and affordability. Those same traits are enhanced by the KA-2414 air filter. To help you escape the expensive and wasteful cycle of buying, using, and trashing disposable filters, the KA-2414 is fully washable and reusable. With a filter service kit like K&N’s 99-5000, occasional cleanings are easy and convenient.
