Product Details

Overview

HPSP Racing 4-valve CNC cylinder head complete set for the Honda Wave 125 (W125), built as a plug-and-play (PNP) SOHC head upgrade with two valve-size options for different airflow needs.

Key Features

4-valve CNC head conversion for W125
Two valve size options: 22/25mm and 24/27mm
Plug-and-play (PNP) fitment for W125
Complete set: head, timing cover, rocker arm, intake, thicker stopper arm, alloy head cover, 4 valves

Specifications

Brand: HPSP Racing
Product: 4 Valve Super Head CNC Complete Set
Compatibility: Honda Wave 125 (W125)
Main spec: Valve sizes 22/25mm or 24/27mm (intake/exhaust)
Material: CNC-machined alloy head, alloy head cover

Variants & Setup

Choose 22/25mm for a milder airflow gain or 24/27mm for a larger valve, higher-flow setup; larger valves generally suit engines already built for higher rpm/airflow. This head requires using a Yamaha LC135 timing gear for correct cam timing engagement - factor this into your build parts list.

Installation & Package

Installation replaces the stock W125 cylinder head assembly and should be done by an experienced mechanic as part of a top-end build. Package includes head, timing cover, rocker arm, intake, thicker stopper arm, alloy head cover and 4 valves; camshaft is NOT included and must be sourced separately.

Summary

HPSP Racing 4-valve CNC super head complete set for Honda W125, in 22/25mm or 24/27mm valve options.

Important Notes

Camshaft is not included in this set - budget for one separately. This head requires an LC135 timing gear to run correctly, so confirm you have or will source that part before starting the install. This is a performance modification part, not a stock replacement head.
