Product Overview
This high-quality Original Cylinder Head Cotter Valve X4 Set is designed to meet or exceed factory performance standards and is suitable for Honda PCX125 (2010-2025), Forza 125 (2015-2025), SH125i (2013-2024), SH Mode 125 (2014-2024), Vision 110 (2011-2025), Pan-European 1100 (1995-1998), CB500 (2015-2022), CB1000 (2011-2012), and Hornet (2025) models.
The Cylinder Head Cotter Valve X4 Set consists of four split tapered retaining clips that seat in the groove of each valve stem and lock the valve spring retainer collar in place, holding the valve spring under correct compression load. If a cotter deforms, fatigues, or dislodges, the retainer releases, the valve spring collapses, and the valve can drop into the combustion chamber, causing catastrophic cylinder head and piston damage. This original replacement is manufactured to original factory specifications, restoring reliable valve train retention to your Honda motorcycles.

Complete Part Guide
The valve cotters on your Honda PCX125 2010-2025 are the only things preventing your valves from falling into the combustion chamber and destroying your engine. Over time, heat cycles and vibration can cause minor fatigue in these tiny but vital steel components. This original Honda replacement set (14781-ML0-720) ensures the valve spring remains locked under tension for thousands of miles. Currently held in stock at Part Hive's London warehouse, order before the 1 PM cutoff for same-day UK dispatch.
We see a lot of Honda PCX-125s in the workshop with "mystery" top-end noise that we eventually trace back to worn or improperly seated valve keepers. When you're dealing with a bike that spends its life at high RPMs filtering through London traffic, you can't afford to take risks with internal engine fasteners. If one of these cotters fails or unseats, the valve drops, the piston hits it, and your repair bill triples instantly. This original Honda Cylinder Head Cotter Valve (14781-ML0-720, 2010-2025) provides the exact factory-spec fitment needed for a secure, high-tension lock. Whenever you're doing a valve clearance check or head rebuild, inspect these for wear and always use original replacements to avoid ending up back on the bench.
