The Royal Enfield Silencer Guard Assembly (Part No. 591871/C) is the genuine OEM chrome-plated guard designed for BS3 & BS4 UCE models of the Classic 350/500 and Bullet 350/500.
This cover fits directly over the silencer section, protecting against heat and debris while preserving the bike’s authentic retro look. Built from durable OEM-grade metal with factory chrome finish, it’s both a functional heat shield and a styling element.
⚠️ Important: This part is specific to BS3 and BS4 UCE models. For BS6 (Classic Reborn / New Bullet J-Series), Royal Enfield uses a larger plate with a different part number and mounting design. Always check your bike’s model year before ordering.
Easy to install with stock hardware, the 591871/C guard is an exact factory replacement. Each unit from Under The Hood is QC-checked, ships with a GST invoice, and is dispatched within 24 hrs for fast delivery.
