Royal Enfield 574266/C – Engine Sprocket M20 Tab Washer / Front Sprocket Lock Washer – Exact Suffix Verification Required
Important suffix-verification notice: the requested SKU is 574266/C. Current Royal Enfield public parts data reviewed for this listing consistently identifies the current documented service reference as 574266/B – TAB WASHER M20, with the older 574266/A – TAB WASHER M20 ENGINE SPROCKET superseded by /B. A reliable current Royal Enfield source confirming a genuine 574266/C revision was not found.
Because exact suffix accuracy is critical for Under The Hood listings, this product is intentionally kept as a verification-required draft. Do not publish or dispatch it as 574266/C until the genuine Royal Enfield packet, dealer invoice, current EPC or authorised supersession record physically confirms the /C suffix.

| Exact /C Fitment | Not verified – packet/EPC confirmation required |
Why the Suffix Matters
Royal Enfield suffixes can represent manufacturing, specification or service-part revisions. A shared base number does not by itself prove that /A, /B and /C are identical or automatically interchangeable.
Current Royal Enfield parts databases reviewed show the replacement path 574266/A → 574266/B. They do not show a verified 574266/C. Therefore this listing does not silently transfer the /B description, fitment or price to /C.
Known /B Applications – Reference Only, Not a /C Fitment Claim
The documented 574266/B washer appears in Royal Enfield parts data for several engine-sprocket/final-drive applications, including:
- Royal Enfield Himalayan 411 / 410 Euro 4
- Royal Enfield Interceptor 650 Twin Euro 4
- Royal Enfield Continental GT 650 Euro 4
Specialist parts sources additionally cross-reference the base 574266 washer family across other Royal Enfield applications. Those broader cross-references must not be used to publish 574266/C fitment until the exact /C suffix is confirmed.
What the Verified /B Part Does
The M20 tab washer is installed at the engine/front sprocket retaining-nut position. After the sprocket and retaining nut are installed to the correct model-specific workshop procedure, the washer tab provides a mechanical locking feature that helps prevent the retaining nut from rotating loose.
This is a locking washer, not the front sprocket itself and not the M20 sprocket nut.

Pack Contents
Do not promise any pack contents for 574266/C until the physical genuine packet is verified.
If the packet is confirmed as a genuine 574266/C service part and its label identifies the same tab-washer component, Shopify quantity should normally represent the actual individual part/pack supplied. Do not infer a multi-piece pack from EPC quantity.
Installation / Safety Notes
- Confirm the exact motorcycle EPC and required suffix before installation.
- Inspect the front/engine sprocket, output shaft splines and retaining nut during service.
- Do not reuse a damaged or previously over-bent locking tab where the workshop procedure requires replacement.
- Use the correct model-specific sprocket-nut torque; do not guess from another Royal Enfield model.
- Form the locking tab only as specified by the service procedure.
- Final-drive and sprocket work should be checked carefully before riding.
Return-Prevention / Dispatch Check
- Read the genuine packet label and confirm it actually says 574266/C.
- Photograph the label before creating or activating the Shopify listing.
- Confirm the factory description printed on that packet.
- Confirm the customer's VIN/EPC specifies the same exact suffix or an authorised supersession.
- Do not substitute 574266/B solely because the base number matches unless Royal Enfield officially confirms interchangeability.
Price
Variant price intentionally left blank. Current exact-source prices found apply to 574266/B or unsuffixed 574266, not the requested 574266/C. Under The Hood's suffix rule requires an exact /C price source before publishing a price.
