Stop grit, water and road muck from chewing up your fork oil seals with the genuine Royal Enfield Dust Seal – Fork (Ø41 mm) — Part No. 594408. The official RE assignment lists 594408 as “DUST SEAL – FORK ASSEMBLY,” and dealer parts books show it on multiple 41 mm fork models, including Continental GT 535, Thunderbird 350/500 (and TBX), Himalayan 410 (Euro 4/BS6) and the 650 Twins (Interceptor 650 / Continental GT 650, Euro 4/5). As an OEM wiper, it matches the stanchion size and recess depth exactly, keeping contaminants out so the inner oil seal (e.g., 594406) lasts longer and stiction stays low.
Ideal when you see cracked lips, perished rubber, or dirt under the wiper. Replace in pairs (one per leg) and inspect fork bushings and oil seals while you’re in there. We list only fiche/dealer-confirmed fitment to minimise returns; see the table below and match by VIN where in doubt.

FAQs
1) Is 594408 the same as the fork oil seal?
No. 594408 is the dust/wiper seal (outer). The inner oil seal for these forks is typically 594406—order both for a leak-free rebuild.
2) Will this fit my Thunderbird X (TBX) 350/500?
Yes—dealer catalogues list NTB 350/500 (Thunderbird family) under 594408. Match your VIN fiche to be certain.
3) Compatible with Interceptor 650 / GT 650 forks?
Yes— 594408 for INT650/GT650 (BSIV/BSVI/E5).
4) What about Himalayan / Scram 411?
Dealers include Himalayan/Scram in 594408 listings; confirm by your VIN fiche and fork size (41 mm).
5) Do I need any special tools?
Use a proper seal driver (or PVC equivalent), clean stanchions, and always replace both dust & oil seals and fork oil to OE spec.
