POLINI Contrast Spring YAMAHA MAJESTY 125

The POLINI contrast spring is an essential component for optimizing the operation of the variator group, especially in the presence of high-performance transformation kits. This spring is designed to handle increases in power and torque, ensuring a more effective response during riding.

With an increase in load compared to the stock spring, POLINI springs offer a 10% improvement for the blue versions (MaxiScooters), 7% for the white ones (Scooters 50), and 15% for the blue ones (Scooters 50). It is important to use the spring with increased load only when necessary, as excessive load can compromise the transmission, causing the belt to jam between the pulleys and increasing wear.

The EVO SLIDER technology, present in some springs, allows for smooth and consistent movement, reducing friction and improving system reliability. This spring is designed to fit perfectly with the rear movable half-pulley, contributing to optimal power transmission.

For correct installation, it is essential to follow the specific instructions, paying attention to the orientation of the spring and checking the condition of the transmission belt. With the POLINI contrast spring, every motorcyclist can enhance their vehicle's performance, ensuring a more responsive and dynamic ride.
