POLINI Contrast Spring SUZUKI BURGMAN 400

The POLINI contrast spring is an essential 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 slippage and to ensure that the movable rear sheave can effectively counteract the movement of the pulley mounted on the crankshaft.

POLINI contrast springs offer an increase in load 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 emphasize that the use of springs with increased load should be reserved for cases where it is truly necessary, as the best performance is achieved by using springs that allow for optimal power transmission with the least possible load.

Additionally, the spring is equipped with EVO SLIDER, a special wear-resistant and self-lubricating material that allows for constant and smooth movement during the variator's shifting excursion. This innovative design helps reduce wear and improve transmission efficiency.

For correct installation, it is essential to follow specific instructions, ensuring that the wear condition of the transmission belt is checked and that the entire variator group is functioning properly before proceeding with the spring replacement.
