Product Overview
This high-quality Original Exhaust Valve is designed to meet or exceed factory performance standards and is suitable for Honda SH150i (2013-2019) and PCX150 (2012-2020) models.
The Exhaust Valve is a precision-ground poppet valve that opens on the exhaust stroke to release spent combustion gases from the cylinder and seals the exhaust port during the intake, compression, and combustion strokes. Operating under extreme heat and pressure, the exhaust valve is highly susceptible to burning, recession, and seat wear, each of which causes compression loss, rough running, increased fuel consumption, and deteriorating engine output. This original replacement is manufactured to original factory specifications, restoring reliable engine performance to your Honda scooters.

Complete Part Guide
Restoring the thermal efficiency and compression of your Honda PCX150 2012-2020 engine is essential for maintaining smooth power delivery on London's fast-moving A-roads. This original Honda Exhaust Valve (14721-KZY-701) replaces burnt, pitted, or warped valves with a factory-spec component, ensuring your engine breathes correctly and meets emission standards. Stocked at Part Hive's London warehouse, order before 1 PM for guaranteed same-day UK dispatch.
We often encounter Honda PCX-150s with reported engine hesitation or a loss of top-end power, and upon checking the exhaust valve, we notice carbon buildup or "pitting" on the sealing face. This damage occurs when the valve spends too much time at high temperatures without sufficient cooling, a common issue for delivery riders navigating long stretches of high-speed London traffic. This original exhaust valve (14721-KZY-701, 2012-2020) is manufactured to match factory weight and heat-resistance tolerances, preventing the off-center vibration and premature wear of the valve guides that occurs with inconsistent metal densities. Replacing this valve during a top-end refresh restores the smooth, silent engine operation required for effortless city riding and ensures the compression is maintained efficiently for maximum fuel economy.
