Keep your Royal Enfield wheels tensioning cleanly and truing straight with the genuine OE spoke nipple — Part No. 593351 (suffix /A). The official assignment page lists 593351/A as “NIPPLE”, and trusted dealer catalogs place it in the Front Wheel / Rear Wheel parts groups. Multiple dealer fitment lists map this nipple to Himalayan (LS410) Euro 4 & Euro 5 variants, and to Bullet 350 ES ABS (BS IV); the official fiche also shows Bullet Trials 500 Euro 4 (front wheel) using this same nipple. That means the thread form, seat angle and length match the corresponding Royal Enfield spokes and rim drilling—no galling, no chewed threads, no guesswork. 

Whether you’re replacing a few corroded nipples or rebuilding a wheel after a pothole hit, choosing OEM ensures consistent metallurgy and plating for long-term tension stability. For the quickest, most durable rebuild, use 593351/A with the VIN-listed spoke PNs and torque to spec. (We list only models confirmed by fiche or two dealer sources to minimize returns.)
