Ninja 250R - EX250J9F

Ninja 250R - EX250J9F

A compact, easy-to-operate chassis and full supersport styling, this model was developed to offer street performance to riders of all skill levels.




ENGINE

  • Highly durable 4-stroke parallel twin is tuned to deliver smooth, step-free power.

  • Idealised intake and exhaust ports contribute to good off-idle response and smooth power delivery.

  • Combustion chamber design optimises the squish area, maximising combustion efficiency and minimising emissions.

  • Valve timing and lift were designed for low and midrange torque.

  • Valves with smaller diameter heads and stems reduce reciprocating weight.

  • Direct valve actuation ensures high-rpm reliability.

  • Pistons feature reinforced heads and strengthening in the pin boss area for high durability.

  • Thick piston rings (longitudinally) minimise oil consumption.

  • The latest generation Denso radiator offers superior cooling performance while minimising space and weight.

  • Fins on the lower side of the crankcase also aid cooling performance.


FUEL SYSTEM

  • Keihin CVK30 x 2 with excellent throttle response, high combustion efficiency and minimise emissions.

  • Twin CVK30 carbies significantly improve driveability.

  • Handy choke ensures a fast warm-up so the catalyser reacts its optimum operating temperature to minimise emissions.

  • The air cleaner features a complex construction with reinforcing ribs that help eliminate reverberation, for reduced intake noise.

EXHAUST SYSTEM

  • The 2-1 exhaust system contributes to low and midrange torque and helps achieve a smooth, step-free power curve.

  • The upswept silencer underwent extensive testing to minimise noise and power loss.

  • The catalysers, is located in the collector pipe, this ensure strict emission regulations are met. Using a high performance catalysers enables power losses to be minimised. Locating the catalyser as close to the exhaust ports as possible maximises its efficiency.

TRANSMISSION

  • Involute splines reduce friction and backlash between gears for easier gear meshing and ensure smooth shifting under power.

  • Spring-type clutch damper contributes to smooth clutch feel, reducing jerkiness at low speeds and minimising shocks when rolling on and off the throttle.

CHASSIS

  • Sturdy frame and swingarm provide a strong, rigid base. Front and rear suspension with firm settings and 17" wheels complete a smooth, rider friendly package that offers confidence-inspiring stability at both high and low-speeds.

TUBULAR 'DIAMOND' HIGH TENSILE STEEL FRAME

  • The frame is constructed of thick-walled tubing for strength and rigidity.

FRONT SUSPENSION

  • Firm settings keep pitching motion to a minimum.

REAR SUSPENSION

  • Uni-Trak rear suspension with 5-way adjustable spring preload.

FRONT AND REAR DISC BRAKES

  • 290 mm front petal disc with a twin piston caliper and a rear 220 mm petal disc with a twin piston caliper ensure excellent stopping power and feel.

ERGONOMICS

  • The Ninja 250R features styling that would not be out of place on our larger supersport models. The striking full-fairing bodywork has a superb fit and finish that looks as good up close as it does from a distance.

  • A slightly forward-slanting seat and wide, raised bars offers a natural riding position. Front cowl and windscreen offer the rider a substantial amount of wind protection.

  • Aggressive dual-lamp headlight design contributes to the sharp image.

  • Slim tail cowl and separate seats further enhance the supersport look.

  • An optional single seat cover can replace the pillion seat for an even more aggressive image.

DETAIL FEATURES

  • Attractive instrument panel features an easy-to-read large face analogue speedometer and tachometer, odometer, trip meter and warning lamps. Clear-lens turn signals contribute to the high-quality look.

  • The Ninja 250R features 17" wheels like our larger supersport models.

  • Sporty low-profile tyres contribute to easy, neutral handling at low-speeds.
