Royal Enfield Fork Cover Tube Short for Bullet 350 ES BSIV & Thunderbird T1 / TBTS – 521067/B
Sold As A Set Of 2 Pcs
521067/B is a genuine Royal Enfield Cover Tube Short. Public OEM-style parts references identify it as COVER TUBE (SHORT) T1, and official Royal Enfield spares evidence confirms that 521067/B is used on Bullet 350 ES BSIV variants. Third-party seller references also support Thunderbird T1 / TBTS usage, which makes this a shared front-end cover component rather than a Thunderbird-only part.
This is the correct OEM replacement when the original fork cover tube is scratched, dented, corroded, bent, or missing during front suspension repair or restoration work. Buyers may also search for it as Bullet 350 fork cover, Thunderbird fork cover tube, Royal Enfield front fork cover, fork shroud cap, and cover tube short.
Because this is a visible front-end trim and cover component, using the correct OEM part helps maintain stock appearance and proper fitment instead of mixing in mismatched local pieces. The safest listing position is Bullet 350 ES BSIV plus Thunderbird T1 / TBTS, with no automatic extension to every old Bullet, Classic, or Electra model.
Why Buyers Need It
This part is usually needed when the front fork cover area is cosmetically damaged or when a bike is being restored back to stock condition. On older Royal Enfield models, small visible front-end parts like this can strongly affect how original the bike looks after repair.
