Royal Enfield 594574 – Head Lamp Rim (Chrome Plating, NT) for Thunderbird 350 (NTB 350) & Thunderbird 500 (NTB 500) | Genuine OEM

The Royal Enfield 594574 Head Lamp Rim (Chrome Plating, NT) is a genuine OEM headlight rim / headlight ring / headlamp bezel designed to restore the factory finish and proper locking fit on the Thunderbird platform. This is the correct replacement when your rim is scratched, rusted, bent from a minor fall, or damaged during headlamp work (bulb upgrade, wiring, meter/visor service).

Unlike many aftermarket “universal chrome rims” that don’t sit flush or lose tension over time, this part number is sold as a certified genuine Royal Enfield spare, meaning it matches OE spec and the part fitted when the bike was new. 

Confirmed fitment is restricted to the catalogue-listed applications only: NTB 350 and NTB 500 (Thunderbird 350 / Thunderbird 500 “NT” family). This is explicitly stated by multiple parts sellers referencing the same OE part number and fitment mapping. 

What’s in the box: 1 x Head Lamp Rim (Chrome).

FAQs 

Q1) Is 594574 the “headlight rim / headlight ring” or the full headlight housing?
This is the head lamp rim only (“HEAD LAMP RIM CHROME PLATING NT”). It is not the full housing/outer shell or lens unit. 

Q2) Which bikes does Royal Enfield 594574 fit exactly?
Confirmed fitment is NTB 350 and NTB 500 (Thunderbird 350 / Thunderbird 500 NT family). If your bike’s parts book shows a different rim part number, do not order this. 

Q3) Will it fit Thunderbird X or later/earlier Thunderbird variants?
Not automatically. While the platform name is similar, headlamp assemblies can differ by year/variant. This listing is restricted to the explicit NTB 350/NTB 500 mapping; please verify with your VIN/microfiche before purchase to avoid mismatch. 

Q4) My rim is loose/rattling—will replacing the rim fix it?
Often yes if the rim’s locking edge/tension is worn or bent. However, looseness can also be caused by damaged housing tabs or incorrect assembly after bulb work. If you’ve recently opened the headlamp, re-check alignment and mounting points first.

Q5) Is this part genuine OEM or aftermarket?
This part number is sold as a certified genuine Royal Enfield spare by established parts channels, and is described as identical to factory-fitted when new.
