Product Overview

This high-quality Original Valve Rocker Arm Set is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2015-2025) and Tricity 125 (2017-2025) models.

The Valve Rocker Arm Set provides both the inlet and exhaust valve rocker arms for the cylinder head, offering a complete valve train restoration in a single kit. Each rocker arm is a pivoting lever that transfers motion from the camshaft lobe to open its corresponding valve against the valve spring. When rocker arm contact pads wear, cracks develop, or the rocker shaft bore becomes loose, valve timing becomes erratic, engine performance drops, a persistent ticking or tapping noise develops, and valves may not open fully, causing power loss and rough running. This original replacement is manufactured to original factory specifications, restoring reliable performance to your Yamaha scooters.

Complete Part Guide

Partial replacement within the valve train can lead to ongoing performance issues because mismatched or worn rocker arms throw off valve timing and pushrod wear,. This original Yamaha NMAX125 Valve Rocker Arm Set (2DP-E2150-01, 2DP-E2160-01) for 2015-2025 models is designed to fully resolve that issue. When only one rocker arm is replaced, the imbalance remains, affecting valve timing and engine efficiency. This complete set restores full system integrity, ensuring both valves operate evenly and reliably. Engineered to Yamaha's original standards, it delivers accurate fitment and dependable durability. Available from Part Hive, order before 1 PM for same-day UK dispatch from our London logistics hub.

Fixing one side of the valve train doesn’t always solve the problem. Typically, an imbalance remains if both rocker arms aren’t replaced together. In workshop experience, we see repeated issues when only partial repairs are done. Riders may not realize it’s a system-based problem.

We replace it with this original Yamaha NMAX-125 valve rocker arm set and it restores full system balance, ensures tight and accurate positioning, and prevents recurring issues.
