Royal Enfield Thunderbird 350 & 500 Side-Panel Grommet, Washer & Boot Repair Kit – 888198

Restore secure, rattle-free mounting of the compatible Royal Enfield Thunderbird side panels with this genuine repair kit. Part number 888198 groups the small mounting rubbers and support pieces used where the side panels locate against the motorcycle.

This is the complete factory-numbered Side Panel Grommet, Washer and Boot Repair Kit for the specified Thunderbird application. It is not a painted side panel, lock kit, sticker set or single loose grommet.

What This Product Is

• Genuine Royal Enfield side-panel mounting repair kit
• Exact part number / MPN: 888198
• Factory description: Side Panel Grommet, Washer and Boot Repair Kit
• Used to renew worn, hardened, split or missing side-panel mounting rubbers
• Designed for compatible Thunderbird 350 and Thunderbird 500 side panels
• Quantity: one repair kit as sealed and factory packed

Key Benefits

• Helps the side panels locate securely in their original mounting points
• Reduces looseness, vibration and rattling caused by worn rubber supports
• Protects panel locating pins and mounting holes from direct metal-to-panel contact
• Useful during side-panel replacement, restoration or lock repair
• Provides the correct factory-numbered kit instead of unmatched generic rubber pieces

Confirmed Compatibility

Exact model descriptions vary across markets. Confirm the old rubber layout, side-panel mounting points and VIN-specific catalogue before opening the package.

Not Automatically Compatible With

• Thunderbird X 350 or Thunderbird X 500
• Classic 350 or Classic 500 merely because an individual grommet looks similar
• Bullet, Electra, Meteor, Hunter or new Bullet 350
• Himalayan, Scram or Guerrilla models
• Interceptor 650, Continental GT 650 or other 650 models
• Modified side panels, custom battery covers or universal bodywork

Some other motorcycles can use an individual grommet with a related base number. That does not make the complete 888198 Thunderbird repair kit interchangeable.

3. Compare the RH and LH side-panel mounting points.
4. Check whether you require the repair kit, painted panel, lock kit or special screw.
5. Confirm the frame brackets and panel pins are not bent or broken.
6. Review product photographs and sealed-package contents.

• Do not pull or twist the panel aggressively against hardened grommets.
• Remove old rubber pieces without damaging the mounting holes.
• Clean the mounting points and inspect them for sharp edges or corrosion.

Important Return-Prevention Note

A correctly supplied rubber repair kit is not returnable or refundable after opening, stretching, greasing, installation, marking, contamination, damage or modification. Ordering the complete Thunderbird kit for another motorcycle because one individual grommet looks similar does not make the supplied product incorrect.

Record one continuous unboxing video from the sealed parcel through inspection of the label and all kit components. Report a wrong, missing or transit-damaged item within 24 hours with the video, labels, photographs and original packaging.
