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
