Royal Enfield Genuine Black Passenger Backrest Mounts – Original Cast Aluminium Pillion Support Arms for J-Series Classic & New Bullet 350 (Part No. KXA00643)

The Royal Enfield Genuine Passenger Backrest Mounts (Part No. KXA00643) are factory-original, premium Genuine Motorcycle Accessories (GMA) engineered explicitly for Royal Enfield’s next-generation J-Series platform. Bolted securely into the existing mounting points on the rear subframe, these heavy-duty support arms act as the structural backbone for a rear passenger backrest setup.

As verified by factory accessory catalogs, this kit features robust, twin-sided cast aluminium arms finished in a highly durable, textured black powder coating. Unlike typical universal aftermarket backrests that easily loosen, vibrate, or rust over time, opting for these genuine OEM mounts guarantees an exact factory fitment, isolates the rear chassis from stress, and positions the backrest cushion at the mathematically perfect height and angle to provide excellent lumbar support.

Key Features:

• 100% Royal Enfield Genuine Accessories (GMA): Factory-engineered and rigourously stress-tested specifically for the J-Series chassis to ensure maximum passenger stability.

• Premium Cast Aluminium Construction: Forged from high-tensile cast aluminium to deliver massive weight-bearing strength without adding unnecessary bulk to the motorcycle’s retro tail section.

• Weatherproof Powder-Coated Finish: Covered in a rugged, matte black powder-coated layer that actively resists monsoon moisture, salt corrosion, UV bleaching, and surface scratches.

• Rock-Solid Foundation: Completely eliminates the dangerous flexing, bending, or shifting common with generic multi-fit welded backrests during hard acceleration or highway cruising.

• Maintains Retro Silhouette: Beautifully sculpted to blend seamlessly into the motorcycle’s vintage aesthetic, preserving the classic look of your rear fender lines.
