Microfiche-based dealer references show this part against the Classic 500 Euro 3 utility box and Continental GT 535 Euro 3 \/ Euro 4 side panel or frame-side locations, depending on the diagram. It is a small but important rubber part that helps with proper mounting, vibration isolation, and preventing panel rattles or misalignment.\u003c\/p\u003e\n\u003cp\u003eUsing a genuine Royal Enfield grommet matters because rubber density, size, and fit are what keep side panels or related mounts seated correctly.
