Royal Enfield 585423/A – Mirror Dummy Ring / Bar-End Spacer for Continental GT 650, GT 535

Royal Enfield 585423/A is the genuine Mirror Dummy Ring / Bar-End Spacer used inside the handlebar ends on several factory clip-on and bar-end–mirror setups. Official parts catalogues and price lists describe it as “MIRROR DUMMY RING” or “BAGUE EMBOUT DE GUIDON”, confirming it as an OEM bar-end ring rather than a generic hardware-shop bush.

On models like the Continental GT 535, Continental GT 650 and Classic 500 Euro 4, this ring sits between the handlebar tube and the bar-end weight / mirror hardware, centering the assembly and giving the OEM mirrors a solid mounting point. It also helps reduce play inside the bar, cutting down rattles and vibration while keeping everything aligned. Many riders use a pair of 585423/A rings to convert to factory-style bar-end mirrors or to cleanly blank off the bar-end when mirrors are relocated.

Because this is a tiny but critical fitment part, using the original 585423/A ensures the correct outer diameter, inner bore and thickness for your Royal Enfield clip-ons or bars. Cheap fabricated spacers often sit loose inside the tube or distort when tightened, leading to wobbly mirrors and damaged bar ends.

If your GT / Classic handlebar is being replaced, restored or converted back to OEM bar-end mirrors, always fit fresh 585423/A dummy rings in pairs for a proper factory finish.

FAQs 

Q1. What exactly does the 585423/A Mirror Dummy Ring do?
It acts as a spacer and support ring inside the handlebar end, allowing the OEM bar-end weight or mirror hardware to clamp securely without wobble or misalignment.

Q2. How many dummy rings does my bike need?
Most GT and Classic handlebar fiches show 2 pieces per bike (one per side). Always check the “Qty” column in your model’s handlebar diagram to be sure.

Q3. Can I use a locally turned spacer instead?
You can, but incorrect thickness or diameter can cause loose mirrors, damaged bars or uneven clamping. 585423/A is factory-dimensioned for the specific clip-ons and bar ends used on these models.

Q4. Does this ring work with aftermarket bar-end mirrors?
Yes, as long as the mirror kit uses the stock bar-end hardware or weights. If your kit replaces the entire internal mechanism, you may not need the dummy ring – check your mirror’s installation guide.

Q5. How do I confirm fitment for my bike?
Open your official Royal Enfield parts catalogue / RE portal, go to the handlebar or “Guidon / Comodos” page, and confirm that your VIN lists 585423/A in the bar-end / mirror area.
