The POLINI black transmission cover is an essential component for Minarelli 50 MY engines, designed to ensure high performance and an attractive aesthetic. This cover, part of the Evolution line, is made for scooters equipped with a long horizontal Minarelli-Yamaha engine and stands out for its advanced technical solutions.
Among the main features, the primary shaft with variator drive pulley stands out, offering greater stability thanks to the inclusion of an additional bearing. This adjustment significantly reduces the bending of the pin, improving the reliability of the system. Additionally, the design of the cover includes strategically positioned air intake and exhaust points to optimize the cooling of the variator group, thus contributing to higher performance.
To ensure further protection, a filtering sponge has been integrated into the air duct, which eliminates impurities and reduces vibrations, allowing for full utilization of the belt's travel on the variator. This cover not only improves engine efficiency but is also available in three trendy colors: black, chrome, and carbon, to suit any style.
