Show original supplier description

The Polini Maxi Hi-Speed 9R variator represents a new approach in drive technology, utilizing 9 variator rollers instead of the typical 6. This larger surface area results in smoother gear changes and significantly quieter engine operation. Polini is known for its high standards in manufacturing quality and performance output, and this variator upholds that reputation. While it may be priced slightly higher than other Hi-Speed series variators, the innovative concept and noticeable performance difference justify the investment. The Maxi Hi-Speed 9R comes as a complete kit, including the variator assembly, a set of 9 variator rollers measuring 20x12mm and weighing 9.2g each, a 15% stronger counterpressure spring, a variator sleeve, a set of sliders, and a tube of grease for the sleeve. Installation instructions and a mounting aid for the bushing are also provided, ensuring a comprehensive package for an upgraded drivetrain.
