Complete Part Guide

This is what stands between your engine and everything the road throws at it. The original Yamaha NMAX125 Engine Crankcase Cover (B6H-E5411-01) for 2021-2024 restores proper protection over the crankcase with a clean, factory-aligned finish. Manufactured to original Yamaha specification, it ensures precise fitment, secure mounting, and dependable durability in real riding conditions. Available with same-day UK dispatch for orders placed before 1 PM from our London hub.

This isn't the first thing riders look at, which is why it gets missed. We've seen NMAX-125s come in with covers cracked or hanging slightly loose, and the rider thought it wasn't a big deal. But once that protection's gone, the engine's more exposed to dirt and impact. It's usually built up over time rather than one big hit. We replace it with the original Yamaha engine crankcase cover, and it sorts it; everything is sealed up and protected again.
