EKS YAMAHA LC135 Y15 28MM STANDARD CUTTING BACKPRESSURE BACK PRESSURE EXHAUST

In a motorcycle exhaust system, back pressure refers to the resistance that exhaust gases encounter as they flow out of the engine and through the exhaust system. While some back pressure is necessary for optimal engine performance and efficiency, excessive back pressure can hinder power output and fuel efficiency. The ideal scenario is to maintain a balance where exhaust gases exit efficiently while still benefiting from the pressure wave to aid scavenging and torque production.
