Product Overview
This high-quality Original Inlet & Exhaust Valve Set is designed to meet or exceed factory performance standards and is suitable for Honda Forza 125 (2015-2025), PCX125 (2021-2024), SH125i (2020-2024), and SH Mode 125 (2021-2024) models.
The Inlet & Exhaust Valve Set provides the complete set of intake and exhaust poppet valves in a single service kit, allowing full valve renewal in one supply. The intake valves open to admit the air-fuel charge, while the exhaust valves open to release spent gases, with all valves sealing the combustion chamber during the remaining strokes. When any valve face or seat recedes, burns, or develops pitting, compression drops, power decreases, idle quality deteriorates, and fuel consumption rises. This original replacement is manufactured to original factory specifications, restoring reliable engine performance to your Honda scooters.

Complete Part Guide
The intake and exhaust valves are the critical gatekeepers of the 2021-2024 Honda PCX125 combustion cycle, controlling the entry of fuel-air mix and the exit of spent gases. Burnt valve seats or carbon buildup on the stems will cause hard starting, backfiring, and a significant loss of top-end speed. This original Honda set (14721-K40-F00, 14711-K40-F00) ensures the specific thermal resistance required for the engine. Available at Part Hive's London warehouse; order before 1 PM for guaranteed same-day UK dispatch.
We frequently see Honda PCX-125s from 2021-2024 that have "tightened up" in the head, leading to valves that don't fully close and eventually burn out. In the high-stress environment of London commuting, poor-quality valves will quickly warp under the extreme heat of the exhaust stroke. This original Honda Inlet & Exhaust Valve Set's (14721-K40-F00, 14711-K40-F00) stem plating and head diameter are machined to exact factory tolerances, ensuring a rattle-free valvetrain and maintaining the vacuum seal needed to prevent the intermittent stalling and "popping" through the intake often caused by low-grade components.
