Kawasaki Ninja 250R specifications and reviewsDOHC 249cc Parallel Twin-cylinder Engine
Cylinder head
Carburetor
Exhaust system
- 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
