Technical Specifications

*Note: Specifications and pricing are subject to change.

Introduction

The Ninja® 250R has always been a great place for beginning riders to get started, but modern sportbike technology means the littlest Ninja is a great choice for more experienced riders as well - especially ones experienced at getting the most for their motorcycle dollar. While its twin-cylinder engine might be small, light and compact, its 8-valve head packs maximum power into every rpm. The 250R screams Ninja performance, from its sleek full fairing and 17-inch wheels, to its UNI-TRAK® rear suspension and triple petal-disc brakes.

Compact parallel-twin design offers good mass centralization for superior handling

DOHC 249CC Parallel Twin-Cylinder Engine

• 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 prevent 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

• 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
• Thin heads and stems on valves for reduced reciprocating weight

Carburetor

• Fine-tuned twin Keihin CVK30 carburetors offer good power feel and low fuel consumption

Reduced Mechanical Noise

• Automatic adjusting cam chain tensioner eliminates mechanical noise caused by a loose cam chain and reduces power-robbing friction loss
• Eliminating mechanical noise allows the use of a freer flowing exhaust for a 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 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

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

• 37mm telescopic front fork with firm settings contribute to the Ninja 250R's smooth, stable handling and enhanced ride control
• UNI-TRAK® rear suspension complements 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 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
• 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
