Product Overview
This high-quality Aftermarket Exhaust Valve is designed to meet or exceed factory performance standards and is suitable for Honda Vision 110 (2011-2016), CRF110F (2013-2024), CRF125F (2013-2024), and CG110SH (2014-2017) 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 aftermarket replacement is designed to match the original part, restoring reliable engine performance to your Honda motorcycles.

Complete Part Guide
The Honda Vision110 Exhaust Valve (14721-KVY-900) controls the release of combustion gases from the cylinder head assembly on 2011-2016 models. A worn, burnt, or poorly sealing exhaust valve can contribute to reduced compression, weaker acceleration, and inconsistent engine performance, making replacement important during top-end repairs or rebuilds. This aftermarket replacement is designed for standard fitment within the cylinder head and supports stable exhaust flow during normal engine operation. Available from Part Hive's London warehouse with same-day UK dispatch on orders placed before 1 PM.
We frequently encounter Honda Vision-110 (2011-2016) units where the rider complains about a sudden loss of top-end speed or the bike struggling to maintain a steady idle when hot. In our experience, this is often caused by a "burnt" 14721-KVY-900 exhaust valve where the edge of the valve face has eroded due to lean-running conditions. Once the seal is breached, the hot gases act like a blowtorch, rapidly destroying the valve and potentially damaging the cylinder head's valve seat. This trade-grade aftermarket replacement is a cost-effective professional solution that restores that vital compression. When fitting a replacement exhaust valve , we carefully inspect the valve seat condition and carry out proper valve lapping to help achieve consistent contact between the valve face and seat during reassembly.
