This 2-stroke exhaust expansion chamber is designed to optimise exhaust gas scavenging and pressure wave timing within the combustion cycle. For 250ccm and 300ccm engines, the specific geometry of the exhaust is critical for pulling spent gases out of the cylinder while retaining the fresh fuel-air charge. Built to align with standard vehicle mounting points, this component serves as a direct replacement part during routine maintenance, repair, or race preparation in professional workshops.
