Always confirm the NGK reference matches the plug specified in the owner’s manual or service manual before fitting. NGK is the world’s largest spark plug manufacturer and the OEM-fill choice for the majority of motorcycle brands. The ER9EH is a standard-tier plug — proven, broadly available, and the right choice for the very common case where the factory specified an NGK standard plug from new.
