"In the category of Valves and Rockers, Inlet/Exhuast Valves"

The exhaust valve is a key component in a motorcycle's engine that controls the release of exhaust gases from the combustion chamber. It opens to allow spent gases to exit the engine and closes to seal the chamber during the intake and compression strokes. Made from high-temperature resistant materials, such as stainless steel or titanium, the exhaust valve must withstand extreme heat and pressure. Proper functioning of the exhaust valve is crucial for efficient engine operation, optimal performance, and emission control.
