#1 Selling Sportbike in the U.S. Offers Superior 250 Performance

With its smooth power delivery, low seat height, and excellent value, the Ninja® 250 has all the vital elements to make it the perfect first sportbike. Powered by a compact liquid-cooled twin-cylinder engine, this Ninja sportbike pleases both ends of the experience spectrum — seasoned riders appreciate the Ninja’s extra highway passing power compared to other bikes in the 250 class, while beginners love the smooth torque delivery at lower speeds. With superior highway performance, aggressive supersport bodywork, and a price tag that packs serious value, the Ninja 250 is a perfect way to get started in a lifetime of motorcycling fun.

The 249cc liquid-cooled, parallel twin engine is tuned for smooth, predictable power delivery around town and excellent performance on the highway, while a smooth-shifting six-speed transmission with positive neutral finder offers the right gear for almost any situation. This efficient engine and transmission help the Ninja 250 provide plenty of enjoyment from the initial learning curve, all the way through advanced sport riding and track days.

Wrapped by a modern aerodynamic fairing and windscreen, the 250 not only looks great, but also delivers effective wind deflection for a wide range of riding situations. An easy-to-read instrument panel with fuel gauge and neutral indicator is another convenient feature for the new rider.

A natural riding position and comfortable ergonomics combine with lightweight handling and nimble response to deliver pure pleasure on city streets. Part of this great handling and stability comes from the full-size 17-inch sportbike wheels.

Track-worthy stopping power is provided by the large petal-shaped 290mm front and 220mm rear brake rotors gripped by powerful two-piston hydraulic calipers. Like Kawasaki’s larger Ninja models, the 250 is equipped with high-quality components and tuned for class-leading performance.

Lightweight and agile, the Ninja 250 delivers low ownership costs coupled with impressive performance… No wonder it’s the #1 selling sportbike in America!

An extensive range of Authentic Kawasaki Accessories are available through Kawasaki dealers.

DOHC 249CC Parallel Twin-Cylinder Engine :
• Compact parallel-twin design offers good mass centralization for superior handling
• Tuned to deliver smooth, step-free power with excellent mid-range and high-rpm power for effective highway performance
• Heavy duty piston rings help prevent oil consumption
• Ample high-rpm performance will please riders who wish to utilize the engine’s full potential

Cylinder Head :
• Combustion chamber designed to maximize combustion efficiency and reduce emissions
• Intake and exhaust ports contribute to good off-idle response and smooth power delivery
• Valve timing and lift designed for strong low
• and mid-range torque
• Direct valve actuation helps ensure reliable high-rpm operability
• Valves feature thin heads and stems for reduced reciprocating weight and efficient flow

Carburetion :
• Twin Keihin CVK30 carburetors offer a nice power feel and help provide low fuel consumption

Reduce Mechanical Noise :
• Self-adjusting cam chain tensioner reduces mechanical noise caused by the cam chain and minimizes loss from power-robbing friction
• Minimizing mechanical noise allows the use of a freer flowing exhaust for better performance
• Complex construction with reinforcing ribs helps eliminate airbox reverberation and reduces intake noise
• Air filter accessible from the side, for easy replacement

Exhaust System :
• 2-into-1 system contributes to the Ninja 250’s low
• and mid-range torque and smooth, step-free power curve
• Slightly upswept silencer extensively tested to determine chamber size, connecting pipe length and diameter to achieve least noise and most power
• Meets strict emission standards with dual catalyzers; one in the collector pipe and the other in the silencer
• Using two catalyzers helps minimize power loss caused by backpressure in the exhaust system
• First catalyzer is positioned close to the exhaust ports for maximum efficiency

Liquid Cooling :
• Denso radiator offers effective engine cooling with minimal space and weight
• Ring fan uses a quiet-running motor that also saves space
• Fins on the lower side of the crankcase helps further cool the engine

Six Speed Transmision :
• Involute splines reduce friction and backlash between gears and shafts for easier gear meshing and smooth shifting under power
• Spring-type clutch damper reduces hesitation at very low speeds and minimizes shocks when rolling on and off the throttle for a smoother clutch feel
• Paper-base friction plates help increase clutch durability

Chasis :
• Sturdy and durable diamond-style frame of thick-walled steel tubing offers confidence-inspiring stability at both high and low speeds
• Beefy swingarm bracket contributes to the frame’s rigidity and helps achieve an optimal balance of chassis stiffness
• Square-tube swingarm with a 60 x 30mm cross section further adds to rigidit

Suspension :
• 37mm telescopic front fork with firm settings contribute to the Ninja 250’s smooth, stable handling and enhanced ride control
• Uni-Trak® rear suspension helps provide predictable handling and good ride comfort
• Rear shock features 5-way adjustable preload, enabling ride height to be maintained whether riding solo or with a passenger

Wheels :
• Features 17-inch wheels like its larger Ninja siblings
• The use of proper sportbike tires contributes to its easy, neutral handling at low speeds and excellent cornering feel

Brakes :
• Large-diameter, 290mm front petal disc and a balanced action two-piston caliper offer excellent braking performance and a natural, direct feeling at the lever
• Two-piston caliper grips the rear 220mm petal disc

Ergonomics :
• Natural riding position with slightly forward-slanting seat and wide, raised handlebars

Bodywork :
• Styling, fit and finish of striking full-fairing bodywork match its Ninja supersport siblings
• Aggressive dual-lamp headlight design, slim tail cowl and separate seats further enhance the supersport look
