Product Overview
This high-quality Original Rocker Arm Exhaust Valve is designed to meet or exceed factory performance standards and is suitable for Honda Forza 125 (2021-2025), PCX125 (2021-2025), SH125i (2020-2024), SH150i (2020-2024), and SH Mode 125 (2021-2025) models.
The Rocker Arm Exhaust Valve is a pivoting lever in the engine's valve train that transfers motion from the camshaft lobe specifically to open the exhaust valve against its spring. Mounted on the rocker shaft, it converts the camshaft's rotational movement into the linear motion required to expel burnt gases from the combustion chamber. When the exhaust rocker arm contact pad wears, cracks develop, or the rocker shaft bore becomes loose, exhaust valve timing becomes erratic, engine performance drops, a persistent ticking or tapping noise develops, and in severe cases the exhaust valve may not open fully, causing back pressure, overheating, and significant power loss. This original replacement is manufactured to original factory specifications, restoring reliable performance to your Honda scooters.

Complete Part Guide
The exhaust rocker arm (14440-K0R-V00) is the key valvetrain link for Honda PCX125 2021-2025, controlling exhaust valve movement. A worn arm restricts gas flow, raises engine heat, and produces metallic tapping from the cylinder head. This original Honda replacement restores smooth valve actuation and stable combustion, protecting engine performance. Stocked at Part Hive's London warehouse, with same-day UK dispatch guaranteed on orders confirmed before 1 PM.
We frequently find 2021-2025 Honda PCX-125s with erratic power delivery and top-end noise, often caused by the roller bearing on this exhaust rocker arm failing under high-heat London filtering conditions. If the exhaust valve timing is slightly off due to rocker wear, you'll experience poor fuel economy and potentially "burnt" valves. This original Honda Rocker Arm Exhaust Valve (14440-K0R-V00) is specifically engineered to survive the thermal stress of the exhaust stroke, ensuring a rattle-free engine and maintains the strict valve clearances required to prevent premature engine fatigue and stalling.
