OEM Honda Grom 125 Rocker Arm Exhaust - (2022) #4

This authentic Honda exhaust valve rocker arm (often labeled as #4 in parts diagrams) is a critical component in the overhead camshaft (OHC) system of your 125cc engine. It transfers motion from the camshaft to the intake valve, ensuring accurate opening and closing for optimal air-fuel mixture intake. Built to Honda's rigorous standards, it's ideal for maintenance, repairs, or rebuilds after high-rev usage or wear. Compatible with the air-cooled, SOHC, 2-valve single-cylinder engine, this part helps maintain smooth performance, reliable idling, and the bike's signature responsive throttle.
