This is one of those parts riders assume is just there to cover things up. From our side, we rely on it to protect what’s underneath. Once it’s worn or damaged, that protection drops straight away. On the NMAX-125, we then start seeing dirt and moisture getting into the area. Riders don’t always notice it early. We replace it with the original Yamaha crankcase cover and it restores proper shielding and keeps the system protected.
