VLVSS017"In the category of Valves and Rockers, Inlet/Exhuast Valves"
The exhaust valve seat is a crucial component in a motorcycle's engine. It is a machined surface in the cylinder head where the exhaust valve makes contact to seal the combustion chamber. The exhaust valve seat ensures a tight seal when the valve is closed, preventing exhaust gases from escaping and maintaining optimal engine performance. Made from durable materials like hardened steel or nickel-based alloys, it withstands high temperatures and pressure. Proper maintenance and machining of the exhaust valve seat are essential for efficient engine operation and longevity.
