Description
Overview:
This Top Cover is a genuine Honda replacement for the mini 4‐stroke GX25 engine as used on machines such as the UMK425LE brushcutter. It is a moulded, impact‐resistant plastic housing in Honda red that sits over the upper engine area to shield key components from knocks, debris, dust, and moisture. By enclosing the cooling path, it also helps maintain correct airflow around the cylinder and flywheel, supporting reliable running under heavy use. The cover is built to Honda's OEM standards for an exact fit and finish, making it a straightforward swap for worn or cracked originals. Supplied to match the original specification under MPN 19720‐Z0H‐020ZB, it is suitable for Honda handheld tools built around the GX22/GX25 engine platform, including the GX25 and UMK425LE.
