HKK Indore HK17A Long Punjab 63mm Big Mouth Chrome Silencer for Royal Enfield UCE
HKK Indore HK17A is the newly launched Long Punjab / Long Punjabi 63mm Big Mouth silencer for compatible Royal Enfield UCE-engine motorcycles. The factory carton identifies the product as HK17A – LP CP (63) SIL.
EXACT PRODUCT
Brand: HKK Indore
Factory Code: HK17A
Box Description: LP CP (63) SIL.
Style: Long Punjab / Long Punjabi
Rear Mouth / Outlet: 63 mm Big Mouth
Finish: Chrome
Engine Platform: Royal Enfield UCE only

CRITICAL FITMENT WARNING: This HK17A version is for compatible UCE exhaust setups. It is NOT for the newer J-Series Classic 350 Reborn, New Bullet 350 J-Series, Meteor 350, Hunter 350 or Goan Classic 350.
What Makes HK17A Different?
The main distinguishing feature is the 63 mm rear mouth. It gives the traditional long-body Punjab silencer a substantially larger and more aggressive outlet than common small-mouth Long Punjab designs.
63 mm refers to the rear mouth/outlet specification, not the header-pipe or inlet diameter.

Sound & Performance
The 63mm Long Punjab is aimed at riders looking for a more pronounced aftermarket exhaust character and a stronger visual presence than the stock silencer. Exact loudness, bass and thump depend on the internal construction, bend pipe / catalytic configuration, engine condition and installation.
No fixed horsepower, torque or mileage gain is claimed.
Construction & Finish
- Long cylindrical Punjab-style body
- Bright chrome exterior
- Large 63mm rear outlet
- Factory-welded mounting brackets
- HKK Indore / Old Is Gold branding on current stock
The exact metal grade has not been manufacturer-confirmed for HK17A, so this listing does not make an unsupported stainless-steel claim.
