Genuine Royal Enfield Thunderbird 350 / Thunderbird 500 UCE Exhaust Pipe Guard Heat Shield – 594474

Model-specific genuine Royal Enfield exhaust-pipe guard for the UCE-generation Thunderbird 350 and Thunderbird 500. Part number 594474 is catalogued as Guard – Exhaust Pipe for NTB 350 and NTB 500 applications.

This is the protective outer guard fitted over the exhaust/header-pipe area. It is not the exhaust pipe, silencer or complete exhaust assembly. Confirm the stamped/required part number, motorcycle generation, mounting-hole layout and existing exhaust system before ordering.

Function and Use

The guard covers a selected exterior section of the exhaust pipe, helping reduce accidental direct contact with the hot pipe and restoring the original visual finish. It is a guard, not thermal insulation: the guard itself can become very hot during and after riding.

Box Contents

• 1 × Genuine Royal Enfield 594474 exhaust-pipe guard

Not included: exhaust pipe, silencer, catalyst, exhaust gasket, clamps, mounting bracket, nuts, bolts, washers, tools or labour unless specifically packed with the supplied part.

Installation Guidance

1. Allow the complete exhaust system to cool fully before touching any component.
2. Confirm the bike, MPN 594474 and mounting pattern before installation.
3. Inspect the exhaust pipe and mounting bosses for cracks, bends, corrosion or previous modification.
4. Compare the new guard with the original before removing protective packing.
5. Position the guard without forcing it or allowing contact that can create vibration or rattling.
6. Use the correct model-specific fasteners and tighten to workshop specifications.
7. Start the motorcycle in a ventilated area and check clearance, vibration and exhaust leaks.
8. Recheck fastener security after the first complete heat cycle.

Professional installation is recommended where the exhaust has been modified, mounting threads are damaged or the correct torque is unknown.

Care and Safety

• Assume the guard is hot whenever the engine has been running.
• Let it cool before cleaning or inspection.
• Use a non-abrasive cleaner suitable for the actual surface finish.
• Do not use the guard as a lifting or tie-down point.
• Investigate rattling promptly; loose hardware can damage the guard or pipe.
