SPRINGS, CLUTCH

Set of contrast springs for Polini variators
Code: 245.082
Polini has created contrast springs for the rear mobile half-pulley to adapt them to the additional load due to elaborate engines that deliver more power and torque. Polini contrast springs prevent belt slippage and consequent premature wear by applying a variable additional load of 10% for Maxiscooters and 7% (White spring) or 15% (Blue spring) for 50 scooters. in any case, mount this type of springs only if strictly necessary, the best performance will in fact always be obtained using the spring which, with less load, allows optimal power transmission.
