Exhaust -SITO PLUS- Piaggio Sfera 50 2nd series (1995-), Liberty 50

The Sito Plus sport exhaust system in original optics definitely belongs to the most inconspicuous sport exhaust systems at all.

Price wise it is mostly a very interesting alternative to an original exhaust. On original cylinders or 50cc DR it is a very good, cheap and unobtrusive choice.

The exhaust is usually throttled by a cone ring in the manifold. The Sito Plus offers quite sporty driving and acceleration values with the E-marking for many models. Which pays off especially in 2 man operation.

And all this with standard optics and discreet sound.

Please note:
Retrofit systems usually always have more power than the original exhaust. In order to obtain an approval, they are throttled at the factory, which can cause a shift in the power band.
In order for the scooter to reach its full power and speed, it may therefore be necessary to adapt the engine to the new exhaust with other variator weights and/or clutch springs, even if it is to be used throttled on a production engine.
