Counter pressure spring Polini -30% for Piaggio
This counter-pressure spring from Polini reduces the pressure by 30% compared to the original spring and is therefore ideal for light tuning.
The counter-pressure spring has the task of pressing the belt pulley in the rear converter against the V-belt. On the other hand, it provides the counter-pressure for connecting” the variator.
