Product Overview

This high-quality Original Camshaft Assy is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2015-2020) and Tricity 125 (2017-2020) models.

The Camshaft Assy is the precision-ground component responsible for controlling the opening and closing of the intake and exhaust valves in correct synchronisation with piston movement. Rotating at half engine speed, its lobes act on the rocker arms to open each valve at precisely the right moment in the engine cycle. When cam lobes wear flat, develop pitting, or the camshaft bearing journals deteriorate, valve lift decreases, engine performance drops sharply, starting becomes difficult, and a persistent tapping or ticking noise develops at idle and under load. This original replacement is manufactured to original factory specifications, restoring reliable performance to your Yamaha scooters.

Complete Part Guide

Loss of timing precision within the valve train can affect overall engine performance, and the original Yamaha NMAX125 Camshaft Assembly (B64-E2170-01) or 2015-2020 models is designed to restore that core timing accuracy. As cam lobes wear, valve operation becomes less accurate, impacting combustion efficiency and smoothness. This component reinstates precise timing and controlled movement for optimal performance. Built to Yamaha's original specifications, it ensures exact fitment and long-term durability. Available now from Part Hive's London hub, order before 1 PM for same-day UK dispatch.

The camshaft is the core of timing control in the engine. Typically, once it wears, everything tied to valve timing starts to feel off. In the workshop, we identify this during deeper inspections or rebuilds. Riders may notice symptoms but not the root cause. We replace it with this original Yamaha camshaft assembly and it restores timing accuracy, ensures a tight and flush fit, and keeps the engine running as intended on your NMAX-125.
