Exhaust system

• 2-into-1 system contributes to the Ninja 250R’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 emissions with dual catalyzers; one in the collector pipe and the other in the silencer
• Using two catalyzers minimizes the power loss
• Positioning the first catalyzer as close to the exhaust ports maximizes its efficiency as well

Chassis

• 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 ideal chassis stiffness balance
• Square-tube swingarm with a 60 x 30mm cross-section further adds to rigidity

Suspension

• 37mm telescopic front fork with firm settings contribute to the Ninja 250R’s smooth, stable handling and enhanced ride control
• UNI-TRAK® rear suspension compliments the rigid frame and provides great road holding ability
• Rear shock features 5-way adjustable preload, enabling ride height to be maintained whether riding solo or with a passenger

Wheels

• Features 17” wheels like its larger supersport brothers
• Low-profile sportbike tires on wide rims contribute to its easy, neutral handling at low speeds

Brakes

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

Six-speed Transmission / Clutch

• Involute splines reduce friction and backlash between gears and shafts for easier gear meshing and smooth shifting under power
• Spring-type clutch damper reduces jerkiness 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

Price

Although lacking a direct competitor, the 2010 Kawasaki Ninja 250R features a $4,299 base MSRP. And by achieving a fuel consumption of 55 to 75 miles per gallon and being cheap to maintain, the small Ninja will get most of that money and even more back to you depending on how much you prefer to ride it so it isn’t just fun, but budget-friendly too.
