Royal Enfield Add-On Relay Lead – KS Wiring RAC00258/D

Genuine Royal Enfield RAC00258/D – ADD ON LEAD - RELAY KS. This is the factory electrical add-on wiring lead used in specific Royal Enfield KS (Kick Start) relay-circuit configurations where the exact parts catalogue specifies RAC00258/D.

Fitment must be matched by exact part number. Public Royal Enfield price data confirms the exact identity and the KS designation, but does not safely establish one universal motorcycle model list for RAC00258/D. Wiring-harness generation, connector shape, relay arrangement and KS/ES configuration can differ even between visually similar Royal Enfield motorcycles.

Meta Description

Genuine Royal Enfield RAC00258/D Add-On Lead - Relay KS. For exact KS wiring applications using this part number. Match EPC, connector and old lead.

Short Hook

Replace a damaged relay sub-lead with the genuine Royal Enfield RAC00258/D KS add-on relay lead instead of cutting, splicing or adapting a different wiring harness.

Detailed Product Description

Royal Enfield RAC00258/D is the genuine electrical service component described in Royal Enfield parts-price data as ADD ON LEAD - RELAY KS. Current 2026 parts data continues to carry the same exact /D suffix, so the Shopify SKU and Google Shopping MPN should remain RAC00258/D.

This component is an add-on electrical lead / small sub-harness associated with a relay circuit. It is not the relay itself and it is not the complete motorcycle main wiring harness. The purpose of an OE add-on lead is to provide the correct factory connector, terminal arrangement, wire routing and electrical interface for the relay circuit specified by that motorcycle's wiring system.

The factory description includes the suffix KS. In Royal Enfield parts terminology, KS is used for Kick Start configurations—for example, genuine parts data separately identifies Bullet 350 KS and Bullet 350 ES components. However, the KS wording alone is not enough to claim that RAC00258/D fits every kick-start Royal Enfield. Exact harness generation and connector architecture must still be matched.

This caution is particularly important because Royal Enfield also lists RAC00285/D – ADDON LEAD - RELAY as a separate genuine part. Specialist listings map RAC00285/D to other Bullet / Classic electrical applications, including Classic 350 ABS BSVI. Therefore RAC00258/D and RAC00285/D must not be merged simply because both are described as relay add-on leads.

Confirmed Compatibility

Fitment Not Confirmed / Check Before Ordering

Not Compatible / Do Not Order For

• Any motorcycle whose EPC specifies RAC00285/D or another relay lead.
• ES-only wiring applications unless RAC00258/D is explicitly specified.
• Any motorcycle with a different connector housing, terminal count or wire routing.
• Modern J-Series, 450 or 650 models solely because they use relays.
• Any motorcycle selected only from photo similarity.

Part Number / Supersession Notes

No RAC00258/D → RAC00285/D supersession or interchangeability is claimed. Both remain separately listed genuine Royal Enfield parts in current price data.

Similar Parts Comparison

When Should This Be Replaced?

• Original relay lead is cut or broken.
• Connector housing is melted, cracked or heat-damaged.
• Terminals are corroded, burnt or loose.
• Wire insulation is damaged.
• Electrical diagnosis confirms an open circuit or excessive resistance in the lead.
• Previous repair used a local splice / incorrect connector and genuine restoration is required.
• VIN-specific EPC or genuine packet confirms RAC00258/D.

Recommended Related Parts to Check

• Correct relay for the exact motorcycle.
• RAC00257/C relay grommet where applicable.
• RAC00240/D relay bracket where applicable.
• Main wiring harness connector and terminals.
• Fuse / fuse-box condition for the related circuit.
• Battery terminals and earth / ground connections.
• Any heat-damaged connector caused by excessive resistance.

What's in the Box

1 × Genuine Royal Enfield RAC00258/D Add-On Lead - Relay KS, as supplied in the genuine packet.

The relay, relay bracket, relay grommet, fuse, main wiring harness and other electrical components are not included unless physically supplied in the packet or explicitly shown in the product photographs.

Installation Notes

• Disconnect the battery before electrical work.
• Confirm RAC00258/D before opening the packet.
• Compare connector housing, pin count, wire colours/routing and terminal orientation with the removed lead.
• Do not cut or modify the genuine lead to force-fit an incorrect harness.
• Inspect the relay and mating connector for heat damage or corrosion before installing the new lead.
• Repair the cause of any burnt connector before replacing the lead.
• Route the wiring exactly as intended so it cannot rub, pinch or contact hot components.
• Reconnect battery only after all connectors are secure.
• Verify the related relay circuit operates correctly before returning the motorcycle to service.

Return-Prevention Note

Before ordering, match all of the following: exact SKU RAC00258/D, KS wiring configuration, connector housing, pin/terminal arrangement, relay circuit and VIN/EPC.

Do not order merely because the motorcycle is a Bullet, Classic, UCE or BS6. Royal Enfield uses more than one relay add-on lead, including the separate RAC00285/D.

Electrical item: this lead is non-returnable once the genuine packet is opened, the connector is plugged in, the lead is electrically tested, modified, installed or used. Correctly supplied parts are not returnable for wrong model selection, wrong diagnosis, connector mismatch, mechanic recommendation, installation attempt or change of mind. Eligible wrong/damaged/missing-item claims require applicable proof and a complete unboxing video within 24 hours under store policy.

FAQs

What is Royal Enfield RAC00258/D?
It is the genuine Royal Enfield Add On Lead - Relay KS, an electrical relay-circuit sub-lead.

What does KS mean?
Royal Enfield uses KS to distinguish Kick Start configurations in its parts nomenclature. That does not mean the lead fits every kick-start model.

Which motorcycle does RAC00258/D fit?
The factory identity is confirmed, but a clean universal model list is not. Use it where the exact VIN/EPC or removed genuine lead specifies RAC00258/D.

Does it fit Bullet 350 UCE Kick Start?
The KS designation makes this a strong candidate for specific Bullet/Standard KS electrical applications, but a direct RAC00258/D Bullet model EPC callout was not located. Confirm by exact VIN/EPC or old lead before dispatch.

Does it fit Classic 350?
Do not assume so. Separate RAC00285/D relay-lead applications are documented for Classic 350 ABS BSVI. Check the exact motorcycle EPC.

Is the relay included?
No. RAC00258/D is the add-on wiring lead, not the relay itself.

Is RAC00258/D the same as RAC00285/D?
No. Both are separately listed genuine Royal Enfield relay leads and no verified interchangeability is claimed.

Can I choose it by connector appearance?
No. Match the exact part number and connector arrangement. Similar connectors can be wired differently.

Can I return it after plugging it in for testing?
No. Electrical parts are non-returnable once opened, connected, tested, installed or used under store policy.

Is the /D suffix important?
Yes. Use RAC00258/D exactly in Shopify SKU, stock labels, invoices and Google Shopping MPN.
