Silencer for motorcycle, scooter, moped

The silencer or muffler, is an essential part of the exhaust a two-wheeler. Its main function is to reduce the noise produced by the exhaust gases as they exit the engine, thus preventing unnecessary noise pollution.

How does a silencer work?

The silencer is usually a tube with perforated internal chambers that are surrounded by a sound-absorbing material. As exhaust gases enter the muffler, they pass through the openings in the walls of the pipe and are then absorbed by the silencer wool.

Silencer Maintenance

Should you notice that your two-wheeler is getting louder and louder, it's time to replace the insulation wool and exhaust gaskets. Maintenance is relatively easy  and requires only a few tools.

If you regularly maintain your motorcycle or scooter, we recommend purchasing an exhaust plug to maintain the effectiveness and life expectancy of the insulation material.
