Part Identification

Short Hook

Exact genuine M6 × 12.8 top-hat compression limiter for the Royal Enfield Guerrilla 450 front lighting / instrument mounting assembly, supplied under current part number RAG00310/C.

Detailed Product Description

RAG00310 is catalogued in the Royal Enfield Guerrilla 450 Lighting & Instrument Cluster assembly as a TOP HAT COMPRESSION LIMITER M6 X 12.8. Two pieces are specified in the assembly.

A compression limiter is used with a mounted assembly to provide controlled support around the fastener area. In a rubber-isolated mounting arrangement, the limiter helps prevent the surrounding mounting material from simply being over-compressed when the fastener is tightened. Correct dimensions therefore matter: a visually similar sleeve, bush or spacer should not be substituted unless the exact part number and specification match.

This component sits within the same front-end parts group as the mounting grommets, L-brackets, headlamp/TFT frame, indicator mounts and instrument mounting hardware. It can be required during front-end repair, instrument/headlamp bracket replacement, accident repair or reassembly where the original limiter is missing, damaged, corroded or deformed.

Confirmed Compatibility

Compatibility Boundary

• Do not assume Himalayan 450 fitment merely because the motorcycles share Sherpa-platform architecture. Body, headlamp and instrument mounting hardware can differ.
• Do not apply this part automatically to Hunter 350, Classic 350, Bullet 350, Meteor 350, Scram or other Royal Enfield motorcycles.
• If another motorcycle's current VIN catalogue explicitly lists RAG00310, follow that catalogue rather than visual similarity.

RAG00310/B vs RAG00310/C — Suffix Note

The base component is RAG00310. Public international genuine-parts catalogues currently show RAG00310/B, while newer supplied inventory documentation records RAG00310/C. This listing is therefore created under the current supplied number RAG00310/C.

Do not treat a Royal Enfield suffix as irrelevant. A suffix can represent a production, supplier or engineering revision. If the old component, invoice or parts book shows /B, confirm the latest supersession through a Royal Enfield VIN-based parts lookup before ordering.

Do Not Confuse With the M5 Compression Limiter

The M6 RAG00310 and M5 RAG00441 parts are not interchangeable simply because both are described as top-hat compression limiters. Match the correct part number and mounting position.

The parts book specifies 2 pieces in the assembly.

Q: Does this listing include a pair?
