Royal Enfield Headlamp / Cover Tube Rubber Spacer 140193/B – Classic, Bullet, Electra & Thunderbird

Genuine Royal Enfield 140193/B rubber spacer used in the front headlamp-casing, cover-tube, steering/headlight and related instrument mounting assemblies on multiple legacy Royal Enfield models. It is a small but important black rubber isolation spacer / rubber washer / headlamp holder that separates and cushions adjoining front-end components.

Royal Enfield catalogues identify this part as RUBBER SPACER. Depending on the model and parts book, the same 140193/B reference also appears in headlamp-casing, steering-stem/headlight, speedometer, front-suspension and headlight-holder diagrams. Order by the exact part number and catalogue location, not only by visual similarity.

Part Identification

Short Hook

Restore the correct OEM cushioning and fit at the Royal Enfield front headlamp / cover-tube assembly with genuine 140193/B—the small rubber spacer often missed during headlight, fork-cover or nacelle reassembly.

Detailed Product Description

The Royal Enfield 140193/B Rubber Spacer is used as a cushioning and spacing component in the motorcycle's front headlamp and surrounding front-end assemblies. On the UCE parts catalogue it is shown in the Head Lamp Casing group for Bullet 350 UCE KS, Electra 350 UCE ES, Classic 350 and Classic 500 EFI. That catalogue specifies 2 pieces in that headlamp-casing application.

On Thunderbird 350 and Thunderbird 500, the same part number appears in the Head Bracket & Steering Stem group and is described as a Rubber Head Lamp Holder; the Thunderbird catalogue shows 4 pieces for that application. On Bullet 500 and several Classic 500 variants, genuine-parts diagrams also place 140193/B in speedometer, headlamp casing, steering-stem/headlight casing, front-suspension and headlight assemblies.

Because this single OEM number is used in more than one diagram and quantity varies by motorcycle, do not assume every bike requires the same number of pieces. Check the exact EPC/parts diagram for the location being repaired.

Installation Notes

• Confirm the exact assembly and quantity from the motorcycle's EPC / parts diagram before dismantling.
• Remove the old hardened or damaged spacer and clean the seating area before fitting.
• Do not cut, stretch or modify the rubber spacer to make it fit a different assembly.
• When rebuilding the headlamp/nacelle or steering-front-end area, confirm all mating bushes and spacers are present before final tightening.
• After assembly, check headlamp casing alignment, fork-cover clearance and absence of abnormal movement or rattle.

Return-Prevention Note

Please verify part number 140193/B, the exact motorcycle generation, assembly location and required quantity before ordering. Royal Enfield has used many small rubber bushes, rings and grommets that can look almost identical. Correctly supplied spare parts are not returnable or exchangeable because of incorrect selection, mechanic recommendation, fitment mismatch 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 within 24 hours under store policy.

Google Shopping Notes

Competitor Gap Analysis

Most listings stop at “Rubber Spacer” or overstate compatibility without telling the buyer where the part is used or how many are required. This listing separates UCE, 500cc and Thunderbird catalogue applications; explains that quantity differs by assembly; distinguishes 140193/B from 143906/B and 110179; and documents the 594503-series cross-references without treating every similar rubber part as interchangeable.

Research / Accuracy Notes

• Royal Enfield UCE parts-catalogue data confirms 140193/B as RUBBER SPACER for Bullet 350 UCE KS, Electra 350 UCE ES, Classic 350 and Classic 500 EFI in the Head Lamp Casing group, quantity 2.
• Royal Enfield Thunderbird 350/500 catalogue data confirms 140193/B as Rubber Head Lamp Holder in the Head Bracket & Steering Stem group, quantity 4, with alternate reference 594503/B.
• Genuine-parts diagrams confirm use on Bullet 500 Euro 3/4, Bullet Trials 500 Euro 4 and multiple Classic 500 variants.
• 594503/A is shown as replaced by 140193/B; 594503/C is kept separate because interchangeability was not proven.
