Part Identification

Short Hook

Replace a missing, bent or damaged air-filter element retaining plate with genuine Royal Enfield 801161, the factory black top retainer used in selected UCE Bullet, Electra and Classic air-filter assemblies.

Detailed Product Description

Royal Enfield 801161 is a genuine air-filter-box component used to retain / cover the air-filter element in selected Royal Enfield UCE motorcycles.

Royal Enfield price lists use the short factory description RETAINER TOP BLACK. The Bullet 500 air-filter parts catalogue expands this to Retainer Top (Black) - Cover Plate, Filter Element, which is much clearer for buyers.

This is not the air filter itself. It is the black retaining / cover plate fitted with the filter element inside the applicable air-filter box assembly.

• Not the suction / intake pipe.
• Not the airbox rubber hose.

Return-Prevention Note / Before You Buy

1. Match exact part number 801161.
2. Confirm you need the air-filter element cover / retainer plate, not the air filter itself.
3. Confirm your motorcycle is the correct UCE generation.
4. Do not order for Classic 350 Reborn or Bullet 350 J-Series.
5. Do not confuse 801161 with 801061.
6. For Classic 500, verify the exact airbox EPC rather than assuming fitment.

Correctly supplied spare parts are not returnable or exchangeable because of incorrect model selection, generation mismatch, component confusion, mechanic recommendation, modified-airbox fitment or change of mind. Orders cannot be cancelled once placed. Eligible wrong-item or damaged-item claims require applicable proof and a complete unboxing video under store policy.

FAQs

What is Royal Enfield 801161?
It is the black top retainer / cover plate used to retain the air-filter element in selected Royal Enfield air-filter boxes.

Is 801161 the air filter?
No. It is the retaining / cover plate. The filter element is a separate component.

Does it fit Bullet 350 UCE?
Yes. Current genuine-parts fitment references list both Bullet 350 UCE kick-start and electric-start variants.

Does it fit Electra 350 UCE?
Yes, for the checked Electra 350 UCE ES application.

Does it fit Classic 350 UCE?
Yes.

Does it fit Bullet 500 UCE?
Yes. The Bullet 500 air-filter EPC explicitly lists 801161, quantity 1.

Does it fit Classic 500?
Do not assume so. The checked combined UCE catalogue uses a different Classic 500 filter-element-with-cover arrangement.

Does it fit the new Classic 350 Reborn?
No. The J-Series motorcycle uses a different intake / air-filter system.

What is the difference between 801161 and 801061?
They are separate Royal Enfield part numbers even though historical parts lists use a similar “Retainer Top Black” description. Do not substitute without EPC confirmation.

Competitor Gap Analysis

Most listings use only the vague factory wording “RETAINER TOP BLACK”. This listing improves buyer understanding by identifying it as the air-filter element cover / retaining plate, separating it from the actual filter and complete airbox, naming the confirmed UCE applications, and explicitly excluding modern J-Series models and the uncertain Classic 500 airbox arrangement.
