Complete Part Guide

The fuel pump unit on your Honda PCX125 2021-2025 models is the primary pressure source for the fuel injection system. Because the engine relies on tight injection timing, a failing pump will cause "flat spots" during acceleration, difficult hot starting, or intermittent stalling in traffic. This original Honda replacement (16700-K1Z-J11) ensures your fuel system meets factory-spec pressure. In stock at Part Hive's London warehouse, order before 1 PM for guaranteed same-day UK dispatch.

We frequently find the 2021-2025 Honda PCX-125 models with "mysterious" power loss at high RPM, which we often trace back to a 16700-K1Z-J11 pump motor that is struggling to keep up with demand. When diagnosing these fuel issues, we listen for a labored priming cycle when the ignition is switched on. A high-pitched whine or a silent tank usually indicates the internal regulator or motor has perished. It's a recurring mistake to ignore the fuel pump and only change the spark plug when the bike is "bogging" under load. This original Honda Fuel Pump provides the exact flow rate and durability needed to prevent lean-running damage, replacing weak, noisy, or failed fuel pump assemblies.
