The Valve Stem Seal (12209-GB4-682) is the original replacement oil-control component for the Honda PCX 125 (2010-2020). Built for precise fitment, it restores the scooter's clean combustion by preventing oil from leaking down the valve guides into the combustion chamber and ensuring a tight seal around the valve stem, shielding the spark plug from oil fouling, and eliminating the blue smoke and carbon buildup associated with perished top-end seals.
Vetted by our Lead Engineer. Leveraging 30 years of mechanical pedigree, every part is inspected for material density and exact tolerances to ensure a 'Right-First-Time' fit.
Guaranteed fitment for Honda PCX125 or free returns.

Product Overview
This high-quality Original Seal Valve Stem is designed to meet or exceed factory performance standards and is suitable for Honda PCX125 (2010-2020), SH125i (2013-2019), SH Mode 125 (2014-2019), Vision 110 (2011-2020), CB125F (2011-2020), and MSX125 (2015-2020) models.
The Seal Valve Stem is a precision elastomeric seal fitted to the valve guide where the valve stem passes through the cylinder head. It prevents engine oil from being drawn down the valve stem into the combustion chamber during intake strokes. When the seal hardens, cracks, or deteriorates with age and heat, oil seeps past the valve stem causing blue exhaust smoke on start-up and under deceleration, increased oil consumption, and eventually fouled spark plugs. This Original replacement is manufactured to original factory specifications, restoring reliable performance to your Honda motorcycles and scooters.

Complete Part Guide
Cold-start blue smoke that clears after a minute or a puff of smoke under hard deceleration both point to valve stem seals that have hardened and lost their seal. Left unchecked, oil consumption climbs and the catalytic converter starts taking the hit. Part No. 12209-GB4-682 is the original Honda PCX125 replacement seal for 2010-2020 models, built to survive cylinder head temperatures. Available at Part Hive's London warehouse, order before 1 PM for guaranteed same-day UK dispatch.
The valve stem seal (12209-GB4-682) is a vital rubber-to-metal component that prevents engine oil from leaking down the valve guides into the combustion chamber of 2010-2020 Honda PCX-125 models. We frequently identify these small seals as the culprit behind "blue smoke" on startup or a sudden increase in oil consumption. In the intense heat of North London's stop-start traffic, the rubber material can become brittle, losing its ability to "wipe" the valve stem clean as it moves. This original Honda replacement part features internal tension springs engineered to maintain a perfect seal without causing excessive friction, ensuring a smoke-free exhaust and protects the intake ports from the heavy carbon buildup that leads to erratic idling.
