1040009/B – Reflex Reflector Mounting Cap for Royal Enfield UCE & BS4 Models (universal rear reflector mount) – Genuine OEM

The genuine Royal Enfield 1040009/B – Reflex Reflector Mounting Cap is the small OE cover used to secure/protect the factory rear reflex reflector mounting point on multiple RE models. Dealer and price-list entries call it exactly “REFLEX REFLECTOR MTG CAP”, so it’s the piece that finishes the reflector fitment, stops it from rattling, and keeps water/dust out of the mount. Because it’s OEM, the bore, shoulder height and plastic grade match the reflector bracket used on Royal Enfield UCE and BS4 bikes, so it sits flush and doesn’t look like an odd aftermarket plug. This is the one you replace when the reflector got knocked off, the cap cracked in a minor tip-over, or you’re rebuilding the rear mudguard/tail tidy and want it to look like stock again. We’re listing it generically for RE UCE/BS4 models because the part is shown as a standalone fastener/trim item in the official part index, not tied to a single bike.

FAQs

Q1. What exactly does this cap do?
It finishes/retains the rear reflex reflector mount so the bracket isn’t exposed.

Q2. My reflector fell off – do I need anything else?
Yes, you may need the reflector + bracket; this listing is only the mounting cap.

Q3. Will it fit a Classic 350 Reborn / Meteor / J-series?
Those often use different, integrated reflectors. Check your tail first; if you don’t see a separate, capped mount, don’t order this.

Q4. How is it installed?
Push-fit / clip-on over the reflector mounting point as per your bike’s tail/bracket.
