Product Overview

This high-quality Original Nut Special 30mm is designed to meet or exceed factory performance standards and is suitable for Honda PCX 125 (2012-2025) models.

The special nut provides a secure threaded fastening point within the drivetrain or suspension assembly, maintaining correct preload and component retention under the vibration and load cycles experienced during normal operation. A loosened or damaged nut compromises component security, risks misalignment of the associated assembly, and can lead to progressive damage if not replaced promptly. This original replacement is manufactured to original factory specifications, restoring correct fastener torque retention and assembly integrity to your Honda PCX 125.

Complete Part Guide

The 30mm special nut on your Honda PCX125 2012-2025 is the primary fastener holding the rear clutch assembly against the heavy pressure of the contra spring. Because this nut is subject to extreme heat cycles and rotational force, it must maintain a specific clamping load to prevent the clutch from shifting. This original Honda replacement (90202-KN7-670) ensures the threads do not strip during installation or operation. In physical stock at Part Hive's London warehouse, place your order before 1 PM for guaranteed same-day UK dispatch.

When performing CVT maintenance on the Honda PCX-125 (2012-2025), we frequently find the 90202-KN7-670 nut has been rounded off or damaged by the use of improper tools like chisels or adjustable pliers. A compromised nut is dangerous, as it secures the clutch spring which is under significant tension. If the threads fail, the assembly can come apart inside the transmission case. Using an original Honda nut ensures the correct "flats" for a 30mm socket, allowing for the precise torque application required to prevent the nut from backing off. We always recommend replacing this nut if the edges show signs of wear or if the threads appear stretched, as a secure clutch assembly is vital for smooth power delivery and belt longevity.
