Royal Enfield 585226/A Fork Bolt Cap (Bolt Cap Fork-GIL) – Interceptor 650, Continental GT 650, Continental GT 535, Himalayan 411 BS4

The Royal Enfield 585226/A Fork Bolt Cap (also called Bolt Cap Fork-GIL) is the genuine top cap that threads into the front fork tube and locks the fork spring and internal assembly in place. This small part plays a big role in front suspension safety, preload and oil sealing on your Royal Enfield.

This OEM cap is used across multiple Royal Enfield models with 41 mm telescopic forks, including the Interceptor 650, Continental GT 650 twins, Continental GT 535 UCE and Himalayan 411 Euro 4. Official parts books and dealer catalogues list 585226/A as the original fork bolt cap for the 650 twins and GT 535 front suspension, and for Himalayan 410 Euro 4 front fork assemblies.

Being an OEM part, it matches the factory thread, seat and length exactly, ensuring correct fitment without any modification. A worn, rounded or damaged cap can make future fork servicing difficult and may compromise sealing. Replacing it with a genuine 585226/A restores proper clamping of the fork spring, keeps dirt and moisture out and maintains the clean, finished look at the top of your forks.

Sold as a single piece (1N) – most bikes require 2 caps per front fork set. Ideal for fork rebuilds, crash repairs or restoring a twin or GT 535 back to original spec.

FAQs

1. Is this cap sold as a pair or single piece?
This listing is for one (1) fork bolt cap. Since most models use two caps (one per fork leg), order 2 pieces for a complete replacement.

2. Will this fit my Interceptor 650 BS6 model?
Yes – Euro 5 / BS6 Interceptor 650 and Continental GT 650 use the same front fork assembly, and dealer parts catalogues for Euro 5 variants show 585226/A as the bolt cap.

3. Is it compatible with Himalayan BS6 (2020 onwards)?
Official cross-reference lists confirm 585226/A for Himalayan 410 Euro 4 only. For BS6/Euro 5 Himalayan, part numbers may differ, so please verify with your VIN or RE service centre before ordering.

4. Do I need any special tools to replace the fork bolt cap?
You’ll need a correct-size socket or spanner and ideally a torque wrench. Always support the front end, release spring preload carefully and follow workshop-manual torque specs.

5. Is this suitable for performance fork upgrades (springs, oil, etc.)?
Yes. As long as you’re keeping the OEM fork tubes and threads, this OEM cap works perfectly with upgraded springs or oil weights.
