Product Overview

This high-quality Original Camshaft Assy is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2021-2024), Tricity 125 (2021-2025), and XMAX 125 (2021-2025) models.

The Camshaft Assy governs the precise timing, lift, and duration of the inlet and exhaust valves in the cylinder head, working in synchrony with the crankshaft to control the four-stroke combustion cycle. As the camshaft lobes wear over time, valve timing drifts, leading to reduced engine power, rough idling, increased fuel consumption, and potential internal engine damage if left unattended. This original replacement is manufactured to original factory specifications, restoring reliable performance to your Yamaha scooters.

Complete Part Guide

Inconsistent performance under load is often linked to irregular valve timing, and the original Yamaha NMAX125 Camshaft Assembly (B6H-E2170-00) for 2021-2024 models is designed to correct it by restoring precise cam-to-valve control. As camshaft wear develops, valve operation becomes less precise, affecting combustion across varying conditions. This component restores accurate timing and smooth valve actuation, ensuring stable and reliable performance. Built to Yamaha's original specifications, it ensures precise fitment and long-term durability. In stock now at Part Hive's London hub, order before 1 PM for same-day UK dispatch.

If the engine’s not running as efficiently as it should, we look at timing, and that’s where the camshaft assembly comes in. Once it’s worn, the engine won’t breathe or burn fuel properly. We see this quite a lot during rebuilds and performance checks on the NMAX-125 bikes. Riders don’t always realize it’s the camshaft causing it. We replace it with this original Yamaha camshaft assembly, and it sorts it, timing back on point, smooth running, and everything sitting right.
