Product Specifications

HKK Phantom Silencer for Royal Enfield Classic 350

The Phantom design gives the motorcycle a more customized exhaust appearance while retaining the classic character associated with Royal Enfield builds. The HKK Phantom Silencer for Classic 350 BS3 BS4 BS6 is intended for riders who want an aftermarket exhaust component rather than a standard factory-style replacement.

Because Classic 350 motorcycles were sold across different BS generations and configurations, exact fitment should always be checked against the motorcycle and the bend pipe being used.

Compatibility with BS3, BS4 and BS6 Models

This HKK Phantom Silencer is intended for compatible Royal Enfield Classic 350 and Standard 350 motorcycles across BS3, BS4 and BS6 applications.

The emission generation alone should not be treated as the only fitment parameter. Bend-pipe design, mounting position, inlet connection and motorcycle configuration can affect installation.

For a custom exhaust setup, confirm the required connection and mounting arrangement before ordering.

Phantom Exhaust Style

The Phantom profile is aimed at riders who want a more distinctive aftermarket appearance compared with a conventional stock-style silencer.

It works particularly well in customized Royal Enfield builds where the exhaust is part of the motorcycle’s overall visual theme.

The exact sound characteristics can vary depending on the motorcycle, bend pipe, exhaust configuration and other components used in the setup. For this reason, no specific sound level or performance figure should be assumed unless supplied for the particular product variant.

Custom Exhaust Applications

The HKK Phantom Silencer can be considered for several aftermarket applications, including:

• Replacement of a compatible aftermarket silencer
• Custom Royal Enfield exhaust builds
• Classic 350 customization projects
• Standard 350 custom builds
• Exhaust styling upgrades
• Builds using compatible aftermarket bend pipes

If the existing motorcycle uses a different bend pipe or mounting arrangement, additional fitment work may be required.

Installation & Fitment

Professional installation is recommended, particularly when the Phantom Silencer is being installed as part of a custom exhaust system.

Before installation, check:

1. Silencer inlet connection
2. Bend pipe compatibility
3. Mounting bracket position
4. Exhaust alignment
5. Clearance from the frame, wheel and other components
6. Exhaust joint and fastening arrangement

A qualified motorcycle mechanic can confirm the required fitment and make any necessary adjustments.

Why Choose the HKK Phantom Silencer?

HKK Phantom Silencer is suited to Royal Enfield owners who want to move away from a standard exhaust appearance and create a more personalized motorcycle.

Its main appeal is the combination of an aftermarket Phantom-style design and compatibility with relevant Royal Enfield 350 custom applications.

For riders comparing aftermarket exhaust options, the most important considerations are motorcycle generation, bend-pipe compatibility, mounting arrangement, intended use and the specific product configuration.

Package Contents

Package generally includes:

• HKK Phantom Silencer — 1 unit

Any additional clamps, brackets, reducers, gaskets, springs or fitting hardware should be confirmed according to the supplied product variant.

Important Fitment Information

Royal Enfield motorcycles can have differences in exhaust mounting and connection arrangements between variants and production generations.

Before purchasing, verify your motorcycle model, BS generation and existing bend pipe arrangement. If you are replacing a previously installed aftermarket exhaust, compare the existing mounting and inlet configuration with the product being purchased.

Road-Use Note

Aftermarket exhaust components may be subject to local noise, emissions and vehicle regulations. Customers should verify applicable requirements before using a modified exhaust system on public roads.
