Details

Polini Torque Spring + Evo Slider Piaggio NRG / Typhoon, diameter = 4.4mm. The spring comes with an "Evo Slider" spring seat.

Torque springs are quite important when it comes to adjusting your transmission. They put pressure on the rear pulley and influence belt tension and clutch performance. Softer springs mean less belt tension and are suited for lower rpm engines, stiffer springs mean more belt tension and are recommended for tuned engines with higher rpm range. Keep in mind that after changing the torque spring you'll likely have to change the variator weights as well to reestablish a balanced system.
