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 250Râ € ™ 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
