Confirmed Compatibility

BS3, BS4 and BS6 Fitment Guidance

This silencer is intended for compatible Royal Enfield UCE-model exhaust layouts. Always check the motorcycle’s year, bend pipe and existing silencer connection before installation.

• 350 UCE models: May be found across BS3, BS4 and selected final BS6 UCE applications.
• 500 UCE models: Generally BS3 or BS4; do not assume a BS6 500 application.
• BS6 motorcycles: Confirm whether the original catalytic-converter/bend-pipe arrangement is being retained.

The “BS6” marking on the chrome unit identifies the manufacturer’s product specification, but it does not mean the silencer is universally suitable for every BS6 Royal Enfield motorcycle.

Check Before Ordering

Please compare the following with your motorcycle before placing the order:

• Motorcycle model and manufacturing year
• UCE engine generation
• Existing silencer inlet connection
• Bend-pipe type
• Mounting-bracket position
• Clamp and gasket requirement
• Whether the catalytic converter is retained

What This Product Is

• One HKK Indore Long Punjab aftermarket silencer

• A replacement/custom exhaust component for compatible UCE motorcycles

Design and Finish

The Long Punjab design uses an extended cylindrical body with a large open-style outlet. This gives compatible UCE motorcycles the stretched, classic exhaust appearance commonly associated with traditional Bullet and Punjab-style builds.

The Chrome version carries HKK “Old Is Gold” branding and factory code HK19C. The Black version offers the same Long Punjab Big Mouth style in a darker finish.

Sound Expectations

Long Punjab Big Mouth silencers are generally selected by riders looking for a more noticeable exhaust note than the stock silencer. The final sound can vary considerably depending on the internal construction, bend pipe, catalytic converter, engine condition and installation.

Please review the available sound video before ordering when the exact exhaust tone is your main priority. No fixed decibel level, baffle count or guaranteed sound character is promised.

Important Fitment and Return Note
