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.
