Royal Enfield Battery Box / Battery Carrier Rubber Cap – 146402/A

Genuine Royal Enfield rubber cap used on the battery carrier / battery box assembly of compatible older Royal Enfield motorcycles. Royal Enfield identifies this part as “BATTERY CARRIER CAP” and the retired-model catalogue describes the same application as “CAP, RUBBER – BATTERY CARRIER”.

In simple buyer language, this is the small rubber battery-carrier cap / battery box rubber. It is not the battery cover panel, battery strap or battery carrier assembly.

Part Identification

What Is This Part?

146402/A is a small genuine rubber cap used as part of the battery-carrier assembly on compatible older Royal Enfield motorcycles. The factory parts catalogue places it with the battery carrier, battery-hold strap, terminal insulator, clip lock and related battery-box hardware.

Because this is a small rubber component, it is easy to confuse it with other battery-box rubbers, liners or grommets. Always match the exact part number and battery-carrier design before ordering.

Confirmed / Catalogue-Supported Applications

Some genuine-parts seller databases also cross-reference 146402/A to additional older applications such as Campus. For any unusual retired-model configuration, match the original battery carrier, EPC and part number before purchase.

Not Automatically Compatible With Newer Models

Do not assume this rubber cap fits modern Royal Enfield motorcycles simply because they also use a battery box. No fitment is claimed here for current J-Series or newer-platform motorcycles unless their own EPC specifically lists 146402/A.

• Classic 350 Reborn / J-Series – not assumed
• Bullet 350 J-Series – not assumed
• Meteor 350 – not assumed
• Hunter 350 – not assumed
• Himalayan 450 – not assumed
• Guerrilla 450 – not assumed
• Super Meteor 650 / Shotgun 650 / Classic 650 – not assumed

Quantity — One Piece vs Two

This Shopify listing supplies 1 individual rubber cap.

The checked Royal Enfield retired-model battery-carrier catalogue shows 2 × rubber caps for the applicable assembly. Therefore:

• If replacing both factory caps in that battery carrier, order quantity 2.
• If only one cap is damaged or missing, order the quantity actually required.
• Do not assume every later battery-carrier design uses two; verify the exact parts diagram.

Part Number History / Alternate Reference

Do not substitute by appearance alone. Royal Enfield has used more than one rubber cap / liner design around different battery-carrier assemblies.
