Kawasaki Ninja 250R Specifications and Reviews

Kawasaki Ninja 250R specifications and reviews


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 250RĂ¢ € ™ 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
