Variator-Kit -POLINI Speedcontrol Hi-Speed- Piaggio 125-150 cc Leader

The new Polini Maxi Hi Speed Variomatic has some new features. The roller tracks are now surface treated with a new process that improves the sliding of the variator rollers compared to the previous model.
The already known grease filling that is sealed by lateral shaft seals has also been revised. An internal spring ensures constant lubrication of the bush. The enclosed counter pressure spring is 7% harder than the original one and improves the contact pressure on the pulley halves. The variator pulleys have a new material mix of nylon and aramid fibres. This gives good sliding properties and a high protection against wear.
