Additional weight or balancing weight that is used in conjunction with the EVO Zündung from Polini on engine cases with rotary valve crankshaft on your Piaggio Ciao, Si, Bravo and Boxer moped / moped to compensate for the resulting imbalance.
The balancing mass gives your engine a smooth, even running when stationary and in operation and improves the «starting behavior». Depending on the setting, even more torque can be achieved with the additional weight.
The flywheel is suitable for all gearbox types that are operated with a rotary valve. In addition to the Polini Speed Engine, this also includes the original engine gearbox.
