Sudah hampir dipastikan 90% Kawasaki Indonesia akan menghadirkan Ninja 250 pada tahun 2008 ini. Gossip terakhir dari orang dalam kawasaki akan di jual sekitaran 38jt s/d 42jt. Mahallll tapi sebanding dengan teknologi yang diusungnya.

At the core of the lightweight Ninja 250R is an engine that thrives on high-rpm excitement. The gutsy 249cc parallel twin has been retuned to spice up its smooth and predictable power delivery. It now offers more low- and mid-range torque thanks to revisions to its dual overhead camshafts and a new 2-into-1 exhaust system. A silky smooth six-speed transmission tops off the sportbike equipment list, enabling the 250R to exploit a powerband that’s sure to please riders with its beginner friendly low-end grunt and a lively top-end rush that’ll keep seasoned veterans satisfied. The coup de’ grace, is its ability to deliver excellent fuel economy.

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 KX™450F 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
