Silencer Polini For Race 4

Polini For Race

The For Race series from Polini includes exhausts as well as crankshafts and clutches for scooters, 50cc supermotos and Vespas. Although the name sounds like ultra-high-quality and high-performance racing parts, this is not quite true.

The exhausts are not road-legal and are theoretically only intended for use on the race track, but due to their performance, which focuses mainly in the lower and medium RPM range, they are more suitable for sports / entry level tuning setups, which are appreciated for their balanced ratio of performance and reliability for everyday use.
The crankshafts are also suitable for sports cylinders, as are the few For Race clutches.

Polini fans looking for maximum power for the racetrack should therefore opt for the Evolution or even the P.R.E. series.

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.
