The POLINI contrast spring is a fundamental component for optimizing the operation of the variator group, especially in the presence of transformation kits that significantly increase the power and torque of the engine. This spring is designed to tackle the challenges of belt slipping and to ensure that the movable rear pulley can effectively counteract the movement of the pulley mounted on the crankshaft.
POLINI contrast springs offer increased loads compared to standard springs: 10% for the BLUE version (MaxiScooters), 7% for the WHITE version (Scooters 50), and 15% for the BLUE version (Scooters 50). It is important to note that the use of springs with increased load should be reserved for cases where it is truly necessary, as the best performance is achieved using springs that allow for optimal power transmission with the least possible load.
Additionally, the spring is equipped with the innovative EVO SLIDER, a special wear-resistant and self-lubricating material that allows for smooth and consistent movement during the variator's shift travel. This design reduces friction and improves the efficiency of the transmission system.
For proper installation, it is advisable to follow specific instructions, paying attention to the condition of the transmission belt and ensuring that the entire variator group functions perfectly.
