Royal Enfield Thunderbird 350 / Thunderbird 500 Front Mudguard Assembly “Lightning” (NT51/VT31) – Genuine OEM 883001

The Royal Enfield 883001 Front Mudguard Assembly – “Lightning” is a genuine OEM front fender developed for the Thunderbird (NTB platform) in the Lightning (NT51/VT31) colour theme. If your current mudguard is dented, cracked around mounting points, rusting, or repainted with an off-shade, this is the correct part-numbered replacement to restore factory alignment and finish mapping.

Most aftermarket “Thunderbird front fender” options look fine online but often fail in real use due to incorrect curvature, misaligned holes, weak paint quality, and vibration rattle. An OEM mudguard reduces these risks because it is the same spec as factory-fit parts in the Royal Enfield spares ecosystem. 

Return-reduction note: This mudguard is finish-specific (“Lightning – NT51/VT31”). If your Thunderbird is a different colour theme (e.g., Twilight/Marine/Stone Black), it will use a different part number—order strictly by 883001 for Lightning fitment accuracy.
