Royal Enfield 805023 – OEM Silencer Assembly (Heat-Resistant Black) for Thunderbird X 350 BS4

The Royal Enfield 805023 Silencer Assembly (Heat-Resistant Black) is the genuine factory-fitted exhaust designed for the Thunderbird X 350 BS4. This silencer maintains the bike’s original exhaust note, ensures correct back-pressure, and preserves compliance with emission and noise standards.

Made from OEM-grade steel with a heat-resistant matte black finish, the 805023 silencer matches the aggressive urban styling of the Thunderbird X 350. Over time, silencers can rust, lose sound quality, or get dented. Replacing yours with this OEM part restores factory performance, durability, and that signature Royal Enfield thump — without the harshness of aftermarket pipes.

Unlike replicas, the 805023 offers exact fitment, original tone, and long-lasting quality backed by Royal Enfield.

⚠️ Note: This silencer is specific to Thunderbird X 350 BS4 models. It does not fit Classic, Bullet, or Thunderbird 500 variants. Always confirm your part number before purchase.
