Features:
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 an emphasis on low- and mid-range power for rider-friendly response
- Pistons feature reinforced heads and strengthening in the pin boss area for increased durability
- Thick piston (longitudinally) rings help minimize oil consumption
- Combustion chamber design optimized to maximize combustion efficiency and reduce emissions
- Ample high-rpm performance will please riders using the full range of the engine

Cylinder head
- Refined intake and exhaust ports contribute to good off-idle response and smooth power delivery
- Valve timing and lift were designed for strong low- and mid-range torque
- Direct valve actuation ensures reliable high-rpm operability
- Valves with thin heads and stems reduce reciprocating weight

Carburetor
- Twin Keihin CVK30 carburetors fine-tuned for good power feel and low fuel consumption


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

Reduced mechanical noise
- Cam chain tensioner with an automatic adjuster, like that on the KX450F motocrosser, eliminates mechanical noise caused by a loose cam chain and reduces power-robbing friction loss
- Silencing mechanical noise allows the use of a freer flowing exhaust for a better sound quality
- Complex construction with reinforcing ribs helps eliminate airbox reverberation and reduce intake noise
- Air filter accessible from the side, for easy replacement

Liquid Cooling
- Latest generation Denso radiator offers superior 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 further helps cool the engine

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

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
- New 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 re-tuned fork 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 / Tires
- 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

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

Bodywork
- Styling matches its larger-displacement Ninja supersport siblings
- Fit and finish of striking full-fairing bodywork on par with that of top-class Ninja supersports
- Aggressive dual-lamp headlight design, slim tail cowl and separate seats further enhance the supersport look
- Front cowling and windscreen offer the rider a substantial amount of wind protection
- Two helmet holders conveniently located under the rear seat
- Under-seat storage can hold a U-lock or similar device
- Two hooks under the tail and the rear passenger pegs provide anchor points for securing items to the rear of the bike

Instrumentation
- Instrument panel features an easy-to-read, large-face analog speedometer along with an analog tachometer, odometer, trip meter, fuel gauge and warning lights
