Royal Enfield 1990725 Black Straightcut Silencer-IN — Classic 350 UCE OEM-Style Silencer

Elevate your Classic 350 UCE with the 1990725 Black Straightcut Silencer-IN, a stylish and functional exhaust upgrade that pairs classic aesthetics with modern design principles. With its all-black finish and straight tip, this silencer delivers a clean, understated look that complements the Classic’s vintage lines.

Marketed in multiple retailer listings as OEM-style and compatible with Classic 350 UCE, it is often sold as a bolt-on replacement for the stock silencer assembly. No major modifications should be required — simply detach the factory unit and install this one in its place. Its design emphasizes maintaining exhaust dynamics, with tuned back pressure for reliable performance.

While this part is widely promoted by aftermarket and semi-OEM sources, confirm via RE’s microfiche / dealer parts catalog to ensure full compatibility before listing as “genuine”.
