Product Overview
This high-quality Original Drive Belt is designed to meet or exceed factory performance standards and is suitable for Honda PCX125 2021-2024 models.
The Drive Belt is a critical component of the CVT (Continuously Variable Transmission), transferring power from the engine to the rear wheel. A worn, cracked, or stretched belt causes slipping, reduced acceleration, loss of top speed, and in severe cases, complete belt failure. This original replacement is manufactured to original factory specifications, ensuring correct fitment, smooth power transmission, and reliable CVT performance.

Complete Part Guide
Maintaining a reliable drive belt on Honda PCX125 (2021-2024) is important for consistent performance in stop-start urban traffic. This original Honda Drive Belt (23100-K1Z-N21) replaces worn, stretched, or heat-affected belts that can cause reduced acceleration, vibration, or uneven power delivery. By maintaining proper friction within the CVT system, it supports smooth operation under load. Available from Part Hive's London warehouse with same-day UK dispatch on orders placed before 1 PM.
We often see Honda PCX-125s (2021–2024 models) with belts that have glazed from repeated heat cycles in stop‑start traffic. In our experience, once the belt surface hardens, riders notice lag when opening the throttle and a drop in top speed. Ignoring these signs can lead to sudden belt failure, sometimes wrapping around the variator and causing further damage. Replacing the belt with this original Honda Drive Belt (23100-K1Z-N21) has proven to be a reliable fix, as factory‑spec belts maintain proper pulley grip and reduce repeat failures for both individual riders and fleet owners.
