PRE wheel axle housing with Piaggio Polini transmission

PRE crankcase wheel axle with Piaggio transmission Polini.

This wheel axle from the Polini brand represents an advanced technical component for high-displacement builds and racing applications. Its main function is to enable the installation of Piaggio gears in PRE 4 Minarelli version engine crankcases or compatible racing crankcases, while also allowing the use of the original Minarelli wheel and accessories to be retained.

The design of this component focuses on improving transmission reliability and ensuring precise engagement of all system elements. Thanks to its manufacturing through precision processes, correct balancing of the rotating masses is achieved, which contributes to greater operational stability in high-displacement builds.

Among its technical advantages, its structure lightened at strategic points stands out to reduce weight without losing mechanical strength. In addition, it features an extension toward the wheel nut end that facilitates the installation of the Polini Torsen TWD swingarm, maintaining perfect system alignment at all times.
