Royal Enfield Bullet 500 EFI / Euro 4 LH Rear Mudguard Carrier – Black – 866179

Genuine Royal Enfield left-hand rear mudguard carrier / rear fender support for compatible Bullet 500 EFI / Euro 4 motorcycles. The exact Royal Enfield part number is 866179, with the factory description MUDGUARD CARRIER LH MOD BLACK.

In buyer language, this is the left-side rear mudguard support stay, rear fender carrier, mudguard side bracket or LH rear fender stay. It is not the rear mudguard itself, not the right-side carrier, not a saree guard and not a luggage rack.

Part Identification

What Is Royal Enfield 866179?

866179 is the genuine left-hand black rear mudguard carrier used in the rear mudguard assembly of compatible Royal Enfield Bullet 500 EFI / Euro 4 motorcycles.

The carrier supports the rear mudguard / fender from the left side and forms part of the rear body-support structure. Customers may also search for this component as a rear mudguard stay, rear fender stay, left mudguard bracket, LH rear carrier, rear mudguard side support or Bullet rear fender support.

This is a structural mudguard support component, not a touring luggage carrier. The word “carrier” in the OEM description refers to the mudguard-support part.

Confirmed Compatibility

Important Production-Date Change

Royal Enfield used an earlier LH rear mudguard carrier before this modified version.

Do not order only by model name. On motorcycles around the production change, compare the original carrier, mounting arrangement and exact EPC / VIN before dispatch.

Left Side Only

This listing is for the LH / left-hand mudguard carrier only.

The matching right-side carrier is separately catalogued as 866180 – MUDGUARD CARRIER RH BULLET MOD BLACK.

Do Not Confuse With Electra Carriers

Royal Enfield separately lists 866182 – MUDGUARD CARRIER LH MOD BLACK ELECTRA and 866183 – MUDGUARD CARRIER RH MOD BLACK ELECTRA. 866179 should not be substituted for 866182 merely because both are black LH carriers.

Bullet 350 Fitment – Verify Before Ordering

Some current marketplace sellers cross-list 866179 for Bullet 350 and Bullet 500. However, the strongest model-specific parts-book evidence checked for this listing directly confirms Bullet 500 EFI / Euro 4. Therefore Bullet 350 is not promoted as confirmed fitment in this listing. For a Bullet 350 customer, match the old carrier, VIN-specific EPC and exact mounting arrangement before dispatch.

Classic 350 / Classic 500 Fitment – Do Not Assume

Some marketplace compatibility tables broadly include Classic models, but this is not sufficient OEM evidence. Do not advertise 866179 as a universal Classic 350 or Classic 500 carrier without an exact model-specific EPC match.
